Check if url

[dreamwest]

Im trying to filter out url from going into the database

 

$search = "http://www.site.com";

if ($search is url ){
echo "search is a url";
	}else{
mysql_query("INSERT INTO tags (tag) VALUES('".$search."' ) ") or die(mysql_error());
}

Your going to want to use some regex (regular expression)..

<?php
  $search = "http://www.site.com";
   $pattern ='/<a href=\"([^\"]*)\">(.*)<\/a>/iU';
   preg_match($pattern, $search, $matches);
  if(count($matches) > 0){
     echo 'URL found'; 
  }
?>

 

This is a basic example... take a look at the link I gave for a more complicated example.
