Dedicated software can make socket MySQL connections to your MySQL server, rather than the HTTP connections you would be making through the browser. I have imported fairly large files with this method using SequelPro (MacOS, free). kevin.thackorie on "Upload a large SQL file" http://forum.wddmportfolios.com/topic/upload-a-large-sql-file#post-624 Fri, 14 Jan 2011 10:15:05 +0000 kevin.thackorie 624@http://forum.wddmportfolios.com/ I'm not sure if this is what you mean, but when trying to import a large .sql file, you may encounter failures due to the sheer size of certain records/tables. Try playing with the configuration settings for MySQL (ex. the file on your web server or "my.ini" if using XAMPP locally at ...xampp\mysql\bin), specifically the "max_allowed_packet" parameter. For instance, I once had to change it from the default 2M to 25M to get a file import to work - the file was nowhere near 600MB, though.

There was a question from the back regarding how to actually put together a decent web design (practical tips on how to mock it up and come up with something successful, etc.). That's obviously a broad question, but one I've asked myself. Here are a few links to resources that will walk you through the process. <a href="http://astore.amazon.com/simplebits-20/detail/0321643380" rel="nofollow">http://astore.amazon.com/simplebits-20/detail/0321643380</a> <-- Dan Cederholm knows CSS inside and out and his books have very current and easy to follow information.

Working from a grid is very important. It'll add an overall sense of consistency and order to your layout which will tie it all together. Don't be afraid to break your grid in some areas.

Someone else asked about how to express your personality if you're applying to an interesting design/development shop and I suggested adding your voice and style to your website.

Especially since we take so much effort to optimize our images, etc. as well. What this does is compresses all your linked css files by flattening all the white spaces and anything else not needed that is stored as memory. <pre><code>01.header('Content-type: text/css'); 02.ob_start("compress"); 03.function compress($buffer) { 04. /* remove comments */ 05. $buffer = preg_replace('!/\*[^*]*\*+([^/][^*]*\*+)*/!', '', $buffer); 06. /* remove tabs, spaces, newlines, etc. */ 07. $buffer = str_replace(array("\r\n", "\r", "\n", "\t", ' ', ' ', ' '), '', $buffer); 08. return $buffer; 09.} 10. 11./* your css files */ 12.include('master.css'); 13.include('typography.css'); 14.include('grid.css'); 15.include('print.css'); 16.include('handheld.css'); 17. 18.ob_end_flush();</code></pre> Follow this link to check out other ways to do this, as well as more info on the one above. <a href="http://www.phpsnippets.info/compress-css-files-using-php" rel="nofollow">http://www.phpsnippets.info/compress-css-files-using-php</a> alexander.nikolov on "Human Readable String - Captchas" http://forum.wddmportfolios.com/topic/human-readable-string-captchas#post-611 Wed, 10 Nov 2010 11:33:28 +0000 alexander.nikolov 611@http://forum.wddmportfolios.com/ This script allows you to create what is known as a "Captcha."

There are two parts necessary to implement this script. The following code will go in a file called "switcher.php": <pre><code><?php setcookie ('sitestyle', $set, time()+31536000, '/', 'yourdomain.com', '0'); header("Location: $HTTP_REFERER"); ?></code></pre> When the user selects an alternate stylesheet, this code will write a cookie that will keep the selected 'sitestyle' (the alternate stylesheet) in memory for a year. The second part that allows this script to work occurs on the PHP content page. In the <head> section, write your stylesheet link as follows: <pre><code><link rel="stylesheet" type="text/css" media="screen" title="User Defined Style" href="<?php echo (!$sitestyle)?'defaultstyle':$sitestyle ?>.css" /></code></pre> Then make a link somewhere in the <body> section that allows them to switch to an alternate style, such as this: <pre><code><a href="./switcher.php?set=red"> click here to change to RED style!</a></code></pre> What this does is calls on switcher.php to set the $sitestyle variable in the link tag to the name specified in the link. If they haven't selected an alternate style, the stylesheet called "defaultstyle.css" will be used by default. shannon.maguire on "Making Thumbnails for a directory of jpegs" http://forum.wddmportfolios.com/topic/making-thumbnails-for-a-directory-of-jpegs#post-602 Wed, 10 Nov 2010 09:21:41 +0000 shannon.maguire 602@http://forum.wddmportfolios.com/ This will make thumbnails for an entire directory of jpeg images. <code> <?php $images = new Imagick(glob('images/*.JPG')); foreach($images as $image) { // Providing 0 forces thumbnailImage to maintain aspect ratio $image->thumbnailImage(1024,0); } $images->writeImages(); ?> </code> mark.pancorvo on "Seconds to string" http://forum.wddmportfolios.com/topic/seconds-to-string#post-601 Wed, 10 Nov 2010 09:18:57 +0000 mark.pancorvo 601@http://forum.wddmportfolios.com/ This function will return the duration of the given time period in days, hours, minutes and seconds. e.g. secsToStr(1234567) would return "14 days, 6 hours, 56 minutes, 7 seconds" <code> function secsToStr($secs) { if($secs>=86400){$days=floor($secs/86400);$secs=$secs%86400;$r=$days.' day';if($days<>1){$r.='s';}if($secs>0){$r.=', ';}} if($secs>=3600){$hours=floor($secs/3600);$secs=$secs%3600;$r.=$hours.' hour';if($hours<>1){$r.='s';}if($secs>0){$r.=', ';}} if($secs>=60){$minutes=floor($secs/60);$secs=$secs%60;$r.=$minutes.' minute';if($minutes<>1){$r.='s';}if($secs>0){$r.=', ';}} $r.=$secs.' second';if($secs<>1){$r.='s';} return $r; } </code> ryan.casey on "Say Hello and Write a Test Post" http://forum.wddmportfolios.com/topic/say-hello-and-write-a-test-post/page/3#post-600 Wed, 10 Nov 2010 09:18:12 +0000 ryan.casey 600@http://forum.wddmportfolios.com/ function checkDateFormat($date) 02 { 03 //match the format of the date 04 if (preg_match ("/^([0-9]{4})-([0-9]{2})-([0-9]{2})$/", $date, $parts)) 05 { 06 //check weather the date is valid of not 07 if(checkdate($parts[2],$parts[3],$parts[1])) 08 return true; 09 else 10 return false; 11 } 12 else 13 return false; 14 } This script makes sure that first, the date is in the correct format.

If you have WHM, go to the Apache Build page, and just build apache with the "Zip" checkbox checked. Unzip File PHP Code <pre><code><?php $zip = zip_open("zip.zip"); if ($zip) { while ($zip_entry = zip_read($zip)) { $fp = fopen("zip/".zip_entry_name($zip_entry), "w"); if (zip_entry_open($zip, $zip_entry, "r")) { $buf = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry)); fwrite($fp,"$buf"); zip_entry_close($zip_entry); fclose($fp); } } zip_close($zip); } ?></code></pre> Zip files more often than not have more than one file inside them, when you open a zip file you need to go through each file. That is what the zip_read and zip_entry_read functions are doing. zip_read is getting all the info for each file, and zip_entry_read is getting the file contents from the info returned by zip_read. zip_entry_name returns the path of the file within the zip. If the file is in a folder inside the zip, you'll need to create the directory before trying to write the file.

If the search is successful, the function returns a value of 1 whereas if the search string is not found, a value of 0 is returned. To clarify: VB’s Instr function will actually return either a 0 or the position of the search string if it is successful. For example: searching the string “Get eggs and milk from the store” for the string ‘milk’ would return a value of 1 in PHP and a value of 14 in VB. Here is some sample PHP code featuring the Preg_Match function in action: <pre><code><? php $sentence = "Paul’s Flash lesson last week gave Dennis a severe migraine.”; If (preg_match("/migraine/", $sentence)) { echo "Prescription: Tylenol 3."; } else { echo "Prescription: Regular Strength Tylenol."; } ?></code></pre> The above code looks for the string ‘migraine’ within $sentence and echo’s a message based on whether it returns a result of ‘true’ (1) or ‘false’ (0). mark.daguilar on "The Mail Function" http://forum.wddmportfolios.com/topic/the-mail-function#post-597 Wed, 10 Nov 2010 09:11:35 +0000 mark.daguilar 597@http://forum.wddmportfolios.com/ Having a form, rather than just listing your contact email on a website can be useful because you can make sure that the person sending the message provides the information that you require (i.e. First Name, Last Name etc.) Providing a form also saves you from having your email address farmed by bots which would mean you could have your inbox flooded with SPAM. The mail function is phrased as: mail (to, subject, body, headers) An example is: mail ( "me@mysite.com", "Contact Us Form", "This is an email from your site", "From: <a href="mailto:you@yoursite.com">you@yoursite.com</a>" ) After the user has provided their information via the form they will receive a reply (either "Your mail was sent successfully" or "We encountered an error sending your mail". <pre><code><?php $to = "you@yoursite.com"; $subject = "Contact Us"; $email = $_REQUEST['email'] ; $message = $_REQUEST['message'] ; $headers = "From: $email"; $sent = mail($to, $subject, $message, $headers) ; if($sent) {print "Your mail was sent successfully"; } else {print "We encountered an error sending your mail"; } ?></code></pre> Save the above code as contact.php What this code does is: 1. Define who you want the mail sent to. We have used <a href="mailto:you@yoursite.com">you@yoursite.com</a> but you should replace this with your email address. 2. Define the default subject for your mail. 3. Collect the message and email fields from the form and assign them to variables 4. Create a 'from' email header 5.

PHP language has an array_intersect function. <pre> <code> <?php $a = array( 1, 3 ); $b = array( 1, 3, 5 ); $c = array_intersect( $a, $b ); print_r( $c ); // result : array( 1, 3 ) ?> </code> </pre> And there's a array_merge function. But, if I want to merge two different arrays, there's a little problem. <pre> <code> <?php // using array_merge(); $a = array( 1, 3 ); $b = array( 5, 4, 3 ); $c = array_merge( $a, $b ); print_r( $c ); // result : array(1, 3, 5, 4, 3); ?> </code> </pre> Obviously, I don't want to merge like that. I want to get rid of that repeated values. In this case, I can use array_unique function. <pre> <code> <?php $a = array( 1, 3, 5, 4, 3 ); $b = array_unique( $a ); print_r( $b ); // result : array( 1, 3, 5, 4 ); ?> </code> </pre> Now, I can put this together in a new function. <pre> <code> <?php // define new function function array_union($a, $b) { return array_unique( array_merge( $a, $b) ); } // Usage of this function. $a = array( 1, 3 ); $b = array( 5, 4, 3 ); $c = array_union( $a, $b ); print_r( $c ); // result : array( 1, 3, 5, 4 ); ?> </code> </pre> Maybe I could put sort function to correct order. :) caroline.mcgregor on "Single-quotes versus double-quotes in a string" http://forum.wddmportfolios.com/topic/single-quotes-versus-double-quotes-in-a-string#post-595 Wed, 10 Nov 2010 08:57:00 +0000 caroline.mcgregor 595@http://forum.wddmportfolios.com/ For us new PHPers, if you have been unsure at times of which to use, single-quotes or double-quotes for your strings, hopefully this will clear up any confusion. In PHP, single-quoted strings and double-quoted strings are not the same. Single-quoted strings are stored as a literal translation - meaning what you see is what you get. Variables enclosed in double-quotes will be have their value used. Example: <pre><code>$year = 2010; $answer1 = "$year"; $answer2 = '$year'; echo $answer1; echo $answer2;</code></pre> The result would be: <pre><code>2010 '$year'</code></pre> The same is true when you have quotes that enclose an entire string - the outer quotes determine how the string is treated, even if you have other quotes inside that string. Example: <pre><code>$year = 2010; $statement1 = "The year is '$year '."; $statement2 = 'The year is " $year".'; echo $statement1; echo $statement2;</code></pre> The result would be: <pre><code>The year is '2010'. The year is "$year".</code></pre> Remember - the exception to the quote rule in strings is the use of the backslash in front of the quote \' or \" (which we all ready know means to ignore the succeeding quote). graine.wightman on "Using the glob() function to find files" http://forum.wddmportfolios.com/topic/using-the-glob-function-to-find-files#post-594 Tue, 09 Nov 2010 23:08:17 +0000 graine.wightman 594@http://forum.wddmportfolios.com/ Somewhat similar to the scandir() function, the glob() function allows you to search for files matching a specified pattern and returns an array of filenames or directories: <pre><code><?php $files=glob(‘*.txt’); print_r($files); ?> /*Output looks like: Array ( [0] => apples.txt [1] => bread.txt [2] => elephants.txt [3] => sailboats.txt ) */</code></pre> Files can also be returned with a path if directions are specified in the query: <pre><code><?php $files = glob(‘../images/a*.jpg’); print_r($files); ?> /*Output looks like: Array ( [0] => ../images/alligator.jpg’ [1] => ../images/amazon.jpg’ [2] => ../images/anaconda.jpg’ ) */</code></pre> The full path to each file can be requested by using the realpath() function on the returned values: <pre><code><?php $files = glob(‘../images/a*.jpg’); /*using this applies the function to each array map*/ $files = array_map('realpath',$files); print_r($files); ?> /*Output looks like: Array ( [0] => C:\wamp\www\images/alligator.jpg’ [1] => C:\wamp\www\images/amazon.jpg’ [2] => C:\wamp\www\images/anaconda.jpg’ ) */</code></pre> Please note: This function does not work on remote files. The files being searched must be accessible on the server's file system.
