how to get directory path only without file name in PHP by web hosting
if you want to know how you can get your file directory path only without the file name you can use this handy function i use often.



<?
function GetFileDir($php_self){
$filename = explode("/", $php_self); // THIS WILL BREAK DOWN THE PATH INTO AN ARRAY
for( $i = 0; $i < (count($filename) - 1); ++$i ) {
$filename2 .= $filename[$i].'/';
}
return $filename2;
}
echo GetFileDir($_SERVER['PHP_SELF']);
?>


so for example when i do this:

echo $_SERVER['PHP_SELF'];

OUTPUT:
/var/www/myfile.php


but i dont want the myfile.php part of it, i only need /var/www/ part. so to do this you can use the function above and it will return this:

OUTPUT:
/var/www/
