Check if link exists

[wadie Wadie]

Function I have (in includes/functions_posting.php):

Code: Select all

function url_exists($url) {
$handle = @fopen($url, "r");
if ($handle === false){
return false;
fclose($handle);
}
else{
return true;
fclose($handle);
}
}

Usage (In posting.php):

Code: Select all

$your_url = "http://www.somewhere.com/index.php";

$your_url = preg_replace(array('#&\#46;#','#&\#58;#','/\[(.*?)\]/'), array('.',':',''), $your_url);

if (url_exists($your_url))
{
echo 'yeah, its reachable';
}
else
{
echo 'what da hell..';
}

I think it works just fine. I get the text echoed on header with an error saying headers already sent.
Instead of echo I now use trigger_error('error message);
Now I get the error the way I want it to be,except that no matter what the url I have in $your_url I keep getting the same error that the URL exists even when it's not!

Also,I'd like to make the function work after I click submit topic and not when I click create new topic.

Thanks.

A: your code will not work if the page "exists" but the server returns HTTP 404 or another "invalid page" status message.

B: use the template system.

So what code changes should I make ? :O

I figured that part out. now I'm having a different issue..

It doesn't matter what's the full URL. it's enough to assign http://www. to the variable

Code: Select all

$post_data['your_url']

and then it will always show that the url exists no matter what's the url I'm trying to post.

I'd really appreciate some help!

Did you get this one figured out?
