Script to check if website resolves, then return result

[David Nelson]

Hey,

 

On my site there are a lot of php-generated links, and sometimes they are broken. I've seen it before, but I was wondering if someone could point me in the right direction of a script that you could define a link to and have it check to see if the page exists/resolves, then return a result either "Working" or "Down" to the user.

 

Thanks everyone.

Well, you could go with the fopen() and if it returns a result it means the page is there..

You could use cURL and check the HTTP response code:

 

<?php
$url = 'http://www.google.co.uk';
$ch = curl_init($url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);
curl_exec($ch);
echo curl_getinfo($ch,CURLINFO_HTTP_CODE);
?>

Okay Sweet! 

 

How would I return a result? I'm real new to PHP so I don't know how to take that code and make it return "Working" or "Down" based off of what it finds. 

 

Thanks for all your help guys. This forum rules!

With my method:

 

<?php
function checkurl($url){
    $ch = curl_init($url);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);
    curl_setopt($ch,CURLOPT_FAILONERROR,TRUE);
    if(curl_exec($ch) !== FALSE){
        return 'URL ok';
    }else{
        return 'Could not connect to site';
    }
    
}
echo checkurl('http://www.google.co.uk');
echo '<br />';
echo checkurl('http://www.madeupurl.com');
?>
