The static method Zend_Loader::loadFile() loads a
PHP file. The file loaded may contain any PHP
code. The method is a wrapper for the PHP function
include().
This method returns boolean FALSE on failure, for example
if the specified file does not exist.
Example 515. Example of the loadFile() Method
<?php
Zend_Loader::loadFile($filename, $dirs=null, $once=false);
The $filename argument specifies the filename to load,
which must not contain any path information.
A security check is performed on $filename.
The $filename may only contain alphanumeric characters,
dashes ("-"), underscores ("_"), or periods (".").
No such restriction is placed on the $dirs argument.
The $dirs argument specifies which directories to search for the
file in. If the value is NULL, only the include_path
is searched; if the value is a string or an array, the directory or directories
specified will be searched, followed by the include_path.
The $once argument is a boolean. If TRUE,
Zend_Loader::loadFile() uses the PHP
function include_once()
for loading the file, otherwise the PHP function
include()
is used.
