How to check error 404 in php

Hello guys, will you please give me a sample code on how to check if the specified url return 404 error..

thanks in advance

 

You can use a .htaccess rule to redirect to a php script when a page doesn't exist on your site:

ErrorDocument 404 http://www.yoursite.com/custom_page.php

 

Try this:

<?php
$site = "http://site.com";
$get = file_get_contents($site);
if(preg_match('#404#', $get)){
echo "This site has 404 Error";
}else{
echo "This site doesn't have 404 Error";
}
?>

PHP:

 

Creating rule @ .htaccess is best...........here.

I think he asked for a checking, not for a redirecting rule...

 

If using php5 try this:
<?php
echo '<pre>'; print_r(get_headers('http://www.google.com')); echo '</pre>';
?>

Yes, but it all depends on what he means with a 'specified url'. If it's a url inserted by the user in a form, then you can use PHP to check it. But if it's a url to your site that the user wants to visit (inserted in the address bar of the browser), then you'll have to use .htaccess.
