Ofcourse. you could use .htaccess
for a QSA
Query apending string. So in your given example this would be something like:
RewriteRule ^facility-search/(.*)$ index.php?search=$1 [QSA,L]
and you can than catch it in your php to perform actions strip them down or anything else so catch it as:
$pathArray = explode('/', $_GET['rt']);
Now you exploded it you can do anything you like with it. The url: www.abc.com/facility-search/school/california/los-angeles/
will give the following output
$pathArray[0]; // returns 'school'
$pathArray[1]; // returns 'california'
$pathArray[2]; // returns 'los-angeles'
I hope you understand the concept.
