Example

Let's get a list of all functions of the JSON extension:

<?php $res = get_extension_funcs('json'); print_r($res); ?>

Code execution result (example):

[ 'json_encode', 'json_decode', 'json_last_error', 'json_last_error_msg' ]

Example

Let's try to get functions of a non-existent extension:

<?php $res = get_extension_funcs('nonexistent'); var_dump($res); ?>

Code execution result:

bool(false)

Example

Let's get the functions of the standard extension (standard PHP functions):

<?php $res = get_extension_funcs('standard'); print_r(array_slice($res, 0, 5)); ?>
