PHP link checker

Hi All

I would like to design a page which takes the url as input and outputs the final url. It should follow any redirects. Any idea on how to get this done.

 

Thank you

Charan

Look into curl as I believe it can follow redirects.

This works for me (PHP5):

 

<?php

function getHeadersCurl($url) { 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL,            $url); 
    curl_setopt($ch, CURLOPT_HEADER,         true); 
    curl_setopt($ch, CURLOPT_NOBODY,         true); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($ch, CURLOPT_TIMEOUT,        15); 
    $r = curl_exec($ch); 
    $r = split("\n", $r); 
    return $r; 
} 

function getNextLocation($headers) { 
    $array = $headers; 
    $count = count($array); 
    for($i=0; $i < $count; $i++) { 
        if(strpos($array[$i], "ocation:")) { 
            $url = substr($array[$i], 10); 
        } 
    } 
    if($url) { 
        return $url; 
    } else { 
        return 0; 
    } 
} 

function getFinalPage($url) {
    $go = 1; 
    $i = 1; 
    while($go && $i < 6) { 
        $headers = getHeadersCurl($url); 
        $go = getNextLocation($headers); 
        if($go) { 
            $url = $go; 
        } 
        $i++;
    }
    return $url; 
} 

echo getFinalPage("http://wave.google.com/");

?>
