Hi, I am doing an URL validator. It needs to be the best URL validator I ever made – and it is already quite functional.

Validating URLs with PHP

I’d be very happy if you’d go there and try to break it and tell me what went wrong if you do break it.

In return you are free to copy the code for your own use.

Usage is very simple, you construct an array with some key/value pairs – look in the source for which value pairs you can use.

Here’s an example from my testapp

    /* Make the options */
    $options['AssumeProtocol'] = @ $slcAssumeProt;

    $options['AllowBracks'] = isset($chkAllowBracks);

    @ $chkProthttp ?  $options['AllowedProtocols'][] = 'http' : '';
    @ $chkProthttps ? $options['AllowedProtocols'][] = 'https' : '';
    @ $chkProtmailto ? $options['AllowedProtocols'][] = 'mailto' : '';
    @ $chkProtnews ? $options['AllowedProtocols'][] = 'news' : '';
    @ $chkProtnntp ? $options['AllowedProtocols'][] = 'nntp' : '';
    @ $chkProtgopher ? $options['AllowedProtocols'][] = 'gopher' : '';
    @ $chkProttelnet ? $options['AllowedProtocols'][] = 'telnet' : '';
    @ $chkProtfile ? $options['AllowedProtocols'][] = 'file' : '';

    $options['Require']['Protocol'] = $chkReqProtocol ? true : false;
    $options['Require']['User'] = $chkReqUser ? true : false;
    $options['Require']['Password'] = $chkReqPassword ? true : false;
    $options['Require']['Server'] = $chkReqServer ? true : false;
    $options['Require']['Resource'] = $chkReqResource ? true : false;
    $options['Require']['TLD'] = $chkReqTLD ? true : false;
    $options['Require']['Port'] = $chkReqPort ? true : false;
    $options['Require']['QueryString'] = $chkReqQueryString ? true : false;
    $options['Require']['Anchor'] = $chkReqAnchor ? true : false;
