The static method Zend_Loader::isReadable($pathname)
returns TRUE if a file at the specified pathname exists
and is readable, FALSE otherwise.
Example 517. Example of isReadable() method
<?php
if (Zend_Loader::isReadable($filename)) {
// do something with $filename
}
The $filename argument specifies the filename to
check. This may contain path information.
This method is a wrapper for the PHP function
is_readable().
The PHP function does not search the
include_path, while
Zend_Loader::isReadable() does.
