I am making use of simplehtmldom which has this funciton:

// get html dom form file
function file_get_html() {
    $dom = new simple_html_dom;
    $args = func_get_args();
    $dom->load(call_user_func_array('file_get_contents', $args), true);
    return $dom;
}

I use it like so:

$html3 = file_get_html(urlencode(trim("$link")));

Sometimes, a URL may just not be valid and I want to handle this. I thought I could use a try and catch but this hasn't worked since it doesn't throw an exception, it just gives a php warning like this:

[06-Aug-2010 19:59:42] PHP Warning:  file_get_contents(http://new.mysite.com/ghs 1/) [<a href='function.file-get-contents'>function.file-get-contents</a>]: failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found  in /home/example/public_html/other/simple_html_dom.php on line 39

Line 39 is in the above code.

How can i correctly handle this error, can I just use a plain ifcondition, it doesn't look like it returns a boolean.

Thanks all for any help

Update

Is this a good solution?

if(fopen(urlencode(trim("$next_url")), 'r')){

    $html3 = file_get_html(urlencode(trim("$next_url")));

}else{
    //do other stuff, error_logging
    return false;

}
