@plsnhat That's a nice function I tend to use three functions for getting files on the include
path this might be overKill but is works for me. I wished they had a file_exists($file,
$on_include_path = false);
here are the three function I use, they are located in a file that I only include once
<?php
function prep_include_path() {
static $path;
$include_path = ini_get('include_path');
if ($include_path !== $path) {
$include_path = str_replace('\\', '/', $include_path);
$include_path = explode(PATH_SEPARATOR, $include_path);
$key = array_keys($include_path);
$size = count($key);
for ($i = 0; $i < $size; $i++) {
if (substr($include_path[$key[$i]], -1) !== '/') {
$include_path[$key[$i]] .= '/';
}
}
$path = implode(PATH_SEPARATOR, $include_path);
ini_set('include_path', $path);
}
return;
}
prep_include_path();
function get_include_array() {
static $path_array;
static $path_string;
$include_path = ini_get('include_path');
if ($include_path !== $path_string) {
$path_array = explode(PATH_SEPARATOR, $include_path);
$path_string = $include_path;
}
return $path_array;
}
function on_include_path($file = null) {
if ($file === null) {
return false;
}
$include_path = get_include_array();
$key = array_keys($include_path);
$size = count($key);
for ($i = 0; $i < $size; $i++) {
$test = $include_path[$key[$i]] . $file;
if(file_exists($test)){
if($include_path[$key[$i]] === './'){
$test = realpath($test);
if(is_dir($test)){
$test .= '/';
}
}
return $test;
}
}
return false;
}
?>
It's not the prettiest and am sure it could be made more elegant on_include_path I would add a
backslash on the end of $file parameter for a directory. personally I think every entry on the
include path should have a closing DIRECTORY_SEPARATOR
