## 1.5. Zend::isReadable()

Returns `TRUE` if a file is readable, FALSE otherwise.

    <?php

    isReadable($filename)

    ?>

The `$filename` argument specifies the filename to check, which 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::isReadable()` does.
