ReflectionExtension::getFunctions — Gets extension functions
Get defined functions from an extension.
This function has no parameters.
An associative array of ReflectionFunction objects, for each function defined in the extension with the keys being the function names. If no function are defined, an empty array is returned.
Example #1 ReflectionExtension::getFunctions example
<?php
$dom = new ReflectionExtension('SimpleXML');
print_r($dom->getFunctions());
?>
上例的输出类似于：
Array
(
[simplexml_load_file] => ReflectionFunction Object
(
[name] => simplexml_load_file
)
[simplexml_load_string] => ReflectionFunction Object
(
[name] => simplexml_load_string
)
[simplexml_import_dom] => ReflectionFunction Object
(
[name] => simplexml_import_dom
)
)
