In this PHP tutorial you are going to learn how the famous post slugs
are created and how you can create your own post-slug function for your
web applications.
By default your publishing system (ie Wordpress) is creating URLs like http://example.com/?p=13. For Search Engine Optimization (SEO) sake one would prefer URLs like http://example.com/hello-world that would dramatically increase your odds of making a lot more sense to search engines (SE).
Here is an actual working example:
Post slug converter
Here's the actual code of the slug converter:
<?
function makeslug($title, $id, $ext=".html") {
$pslug = preg_replace("/[^a-zA-Z0-9 ]/", "", $title);
$pslug = str_replace(" ", "-", $pslug);
$pslug = strtolower($pslug);
$pslug = $id."_".$pslug.$ext;
return $pslug;
}
if(isset($_POST['title']) && isset($_POST['id'])) {
$id = $_POST['id'];
$title = $_POST['title'];
$url = makeslug($title, $id);
echo "From <strong>" .$title. "</strong> our script created <strong>" .$url. "</strong><br /><br />";
echo "<a href=" .$url. ">".$title."</a><br /><br />";
echo "Notice the generated URL of the above link.";
}
else {
?>
<strong>Post slug converter</strong><br />
<form action=<?=$_SERVER['PHP_SELF'];?> method=post name="conv">
<input type="text" name="title" value="Enter title to convert" onfocus="if (this.value == 'Enter title to convert') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Enter title to convert';}" ><br /><br />
<input type="text" name="id" value="Enter ID" onfocus="if (this.value == 'Enter ID') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Enter ID';}" /><br />
<input type=submit name="conv" value="Convert">
</form>
<? } ?>
By reading our PHP Forms and Input form text switch using JavaScript tutorials, you will get a general ideea of the techniques used here.
The new PHP code we are using is the makeslug function. This is a basic user defined php function with two required parameters ($title and $id) and an optional parameter $ext.
By using PHP's preg_replace this function removes any non a-zA-Z0-9 characters from our string. Then by using str_replace, it replaces all white spaces with a dash "-".
Then by using strtolower it converts all of our strings characters to lowercase and then returns our final converted string (post slug, friendlyurl).
- Install Photoshop on Ubuntu Linux
Believe it or not Photoshop CS2 is now fully supported on Ubuntu Linux using Wine. For a long period of time I was eager in switching to Ubuntu but the incompatibility of my most used Windows based applications always made me switch back to Linux. No more Windows based Photoshop skills, now you can powerup Photoshop on Ubuntu.

 Every AdSense Publisher had nightmares when hearing of all the horror stories where people get banned from AdSense because someone else used their AdSense code on malicious sites, breaking the Google AdSense TOS.
This all ended when Google decided to listen to the community and build the Allowed Sites feature.
