PHP, validate user submitted URL with particular domain

I'm trying to validate a URL using a Regex with PHP. I need a pattern that considers valid:

Any other is not valid, so you can't have ssh://, a .com domain, etc.

I tried the following pattern:

/(((http|ftp|https):\/{2})+(([0-9a-z_-]+\.)+(pf)(:[0-9]+)?((\/([~0-9a-zA-Z\#\+\%@\.\/_-]+))?(\?[0-9a-zA-Z\+\%@\/&\[\];=_-]+)?)?))\b/imuS

but I've lost many hours (and hairs) trying to make it work the way I need it to work.

Any suggestion is appreciated.

^((http|ftp)[s]?://)?([\w-/.]+)(.pf)([\w-/.\&\%\$+\?]+)?$

Handles everything requested, unless I interpret the question wrong. Test here: http://www.cuneytyilmaz.com/prog/jrx/ Please, do tick case insensitive.

to implement in php use /^((http|ftp)[s]?://)?([\w-/.]+)(.pf)([\w-/.\&\%\$+\?]+)?$/i

This is a better way of doing what you want, granted it doesn't use regular expressions, but it is easier to maintain and uses native php functions for that reason:

<?php
function isValidPFurl($url) {
    if (strpos($url, "://" ) === false) {
        $url = 'http://' . $url;
    }
    $valid = filter_var($url, FILTER_VALIDATE_URL);
    if ($valid !== false) {
        $parsed = parse_url($valid);
        $host = $parsed['host'];
        $scheme = $parsed['scheme'];
        $valid = false;
        switch($scheme) {
            case 'ftp':
            case 'http':
            case 'https':
                $p = explode(".", $host);
                if ($p[sizeof($p) - 1] == 'pf') {
                    $valid = true;
                }
                break;
            default:
                $valid = false;
        }
    }
    return $valid;
}

$testUrls = array(
"http://example.pf/",
"example.pf",
"www.example.pf",
"ftp://example.pf",
"https://example.pf",
"ssl://example.pf"
);
foreach ($testUrls as $url) {
    echo "is $url valid? ", (int) isValidPFurl($url), "\n";
}

Try this

/((https?|ftp):\/\/.)?(www\.)?[a-zA-Z0-9]+(\.[a-zA-Z0-9]+)*\.pf/i

I am not sure whether this is the best solution.

As per your need, you have to try this

 <?php
        $regex = "((https?|ftp)\:\/\/)?"; // SCHEME
        $regex .= "([a-z0-9+!*(),;?&=\$_.-]+(\:[a-z0-9+!*(),;?&=\$_.-]+)?@)?"; // User and Pass
        $regex .= "([a-z0-9-.]*)\.([a-z]{2,4})"; // Host or IP
        $regex .= "(\:[0-9]{2,5})?"; // Port
        $regex .= "(\/([a-z0-9+\$_-]\.?)+)*\/?"; // Path
        $regex .= "(\?[a-z+&\$_.-][a-z0-9;:@&%=+\/\$_.-]*)?"; // GET Query
        $regex .= "(#[a-z_.-][a-z0-9+\$_.-]*)?"; // Anchor
    ?>

There is parse_url function in php.

Then it will be much easier to validate the scheme and host of the result of parse_url.
