Sometimes it is helpful to check for the existance of a file
which might be found by using the include_path like in
<?php
include("file_from_include_path.php");
?>
A simple function iterates the include_path and tries all
possibilites, returns translated_local_path on success or false
if not found.
<?php
function mappath($path_to_translate){
$IncludePath=explode(PATH_SEPARATOR,get_include_path());
foreach($IncludePath as $prefix){
if(substr($prefix,-1)==DIRECTORY_SEPARATOR)
$prefix=substr($prefix,0,-1);
$try_path=sprintf("%s%s%s"
,$prefix,DIRECTORY_SEPARATOR,$path_to_translate);
if(file_exists($try_path))return($try_path);
}
return false;
}
?>
