Checking a url format

[graham23s]

Hi Guys,

 

i was wondering if there was a better way to check a url format than the one i made:

 

<?php
  // check the url format 
  if (!preg_match("/^http:/", "$var_url"))
  {  
   $errors[] = "Your URL looks invalid, does it start with http://"; 
  }
?>

 

as you can see its basic lol

 

thanks guys

<?php
$check = substr($url, 0, 7);

if($check != 'http://')
{
$errors[] = "Your URL looks invalid, does it start with http://"; 
}

?>

An easier way would be to use:

checkdnsrr($domain, "ANY")

if you want to check if a domain exists or not.
