get_headers() alternative in php4

I want to check a file on my server root directory. I have to give a full URL in the path. The file_exists() do not work with this, get_headers() function is in php5. Can anyone suggest an alternative.

If you want to check whether file exist simply use


//file to check if exist
$file = 'File Name';
if (file_exists(dirname(__FILE__).'/'.$file))
{
//file exist do whatever you want
}


To work in your case just save that code somewhere in your root directory and run it

Thanks for helping me. I will try to figure it out.

Solution: Update to PHP5.

or simply use the appropriate PHP4 functions

<?
echo '<pre>';
print_r(apache_request_headers());
print_r(apache_response_headers());
?>

to check if a url exists you could use fsockopen() (http://www.php.net/fsockopen)
