Get Contents With 404

I am running a script that loops through various URL's and does a $content=file_get_contents($url);

How do I do an "If URL Not Found (404) Then Do Something, Else Run Rest Of Loop"

Right now when there is a 404 error, the script stops and outputs a php Warning saying that the file_get_contents returned a 404. A 404 error is ok for this script... I want to move on to the next URL without stopping the script.

Thanks

 

you can try;
$content=@file_get_contents($url);

@ prevents function to print errors on the page.

 

Won't if(!$content) work?

 

an exclamation point just means if something is not true. Basically

if($content)

PHP:

is the same as

if($content == true)

PHP:

and

if(!$content)

PHP:

is the same as

if($content != true)

PHP:

and also

if($content == false)

PHP:

(the operator "!=" means "not equal to")

 

if (!$content = @file_get_contents($url))
{
    continue;
}

PHP:
