Still many people using query string / get method for their URL to getting the value from the user , but these query strings are not Search engine friendly , To create a searchengine friendly url you can make use of URI segments

asvignesh.in/blog_post?title=post_name Instead we can use like asvignesh.in/blog_post/post_name

I explain you how to fetch the URI segments

Here is a set of two php functions that I use regularly to quickly get a specific URI segment or return all segments available.

These are very helpful if you have written or are writing your own custom SEF urls

<?php
function getUriSegments() {
   return explode(“/”, parse_url($_SERVER[‘REQUEST_URI’], PHP_URL_PATH));
}
function getUriSegment($n) {
   $segs = getUriSegments();
   return count($segs)>0&&count($segs)>=($n-1)?$segs[$n]:”; //if uri segment us available then return uri else return ‘null’
}
?>
<?php
// if the url is http://asvignesh.in/foo/bar/wow
echo getUriSegment(1); //returns foo
echo getUriSegment(2); //returns bar
var_dump(getUriSegments()); //returns array(0=>’foo’, 1=>’bar’, 2=>’wow’)
?>
