SEO URLs with PHP

SEO URLs with PHP: "SEO URLs with PHP"

Do you want to implement your own search friendly url engine? Limeware has its own URL rewrite engine which is not dependent on Apache mod_rewrite. It is relatively easy to implement in other systems or to adapt to your specs.This is an evil url: www.notfriendly.com/index.php?menuID=28&type=articleThis is a good url: www.friendly.com/index/menuID_28-type_articleMy solution in Limeware CMS is to do the URL processing in PHP. If you follow these steps you will have your own Apache compatible URL rewrite engine in no time.Step 1.In your .htaccess file (If you don't have one, then create a new one in the folder where your index.php resides) add the following:
ForceType application/x-httpd-phpThis simply tells your apache server to treat "index" in the url as "index.php". If you are using a server other than apache, then you will need to configure it to do this.Step 2.Implement the class below so that an instance is create each time index.php is executed. What this does is it takes the special url www.friendly.com/index/menuID_28-type_article andsplits it into www.friendly.com/index/ and menuID_28-type_article strings, then it creates an array:array['menuID'] = 28array['type'] = articleYou cannot use $_GET['paramName'], instead call getItem($key) method in UrlFilter passing the name of the parameter you want, for exaple: $this->urlFilter -> getItem("menuID").You can use any number of parameters, and name them as you wish, all you have to do is use the getItem() method and you got yourself nice URLs. Ofcourse you will need to build your links correctly for this to work, use getOriginalUrl() for this, then add your parameters to it: /param_value-param2_value2-param3_value3 and so on...
