    Hi,

    I want to be able to put a simple if statement or something to stop broken images looking crap!

    I wan't a page to show an image of my choice if the img src isn't there.


    Basically - I'm adding the favicon.ico of others websites to my website... but if they havn't got a favicon I don't want it to show a placeholder - I want it to display a default icon.


    Something along the lines of

    if img src broken then display default.ico
    PHP:

    If anyone has any ideas, I'd be very appreciative.

function remote_file_exists($url)
{
    $headers = @get_headers($url);
    return preg_match('/^HTTP\/1\.\d\s+200/i', $headers[0]);
}

// Example:

if (remote_file_exists('http://example.com/favicon.ico'))
{
    // Exists
}
else
{
    // Doesn't exist
}
    PHP:

    Untested but should work. (PHP 5 is needed though)
