Diagnostic PHP: Get All User Functions

Last updated October 10th, 2018 at 08:04 am

Sometimes I want to see all the user-defined functions that are in memory when a page loads. Maybe the page doesn’t need certain functions and I can realize performance improvements by removing them. And sometimes — I’m being candid here — I copy functions from one application into a library file for another and don’t need any of them for the current application. This function, offering some diagnostic PHP, helps.

function diag_defined_user_fuctions( $sort = true, $echo = true ) {
	$funcs = get_defined_functions();
	$u_funcs = $funcs['user'];
	if ( $sort ) {
		sort($u_funcs);
	}
	if ( $echo ) {
		echo 'User Functions:<pre>' . print_r($u_funcs, true) . '</pre>';
	} else {
		return $u_funcs;
	}
}

The native PHP function get_defined_functions returns a multidimensional array consisting of all defined functions, including internal functions and user-defined functions.

By calling my function with the default arguments (

$sort = true and $echo = true)…

diag_defined_user_fuctions();

… I get a result that looks like this:

User Functions:

Array
(
	[0] => all_session_elements
	[1] => arrigate_disallowed_email_chars
	[2] => arrigate_disallowed_href_chars
	[3] => calendar_date
	[4] => callout_box
	[5] => check_convert_date_entry
	[6] => cmp
	[7] => convert_any_datestring_for_mysql
	[8] => convert_date_ymd
	[9] => convert_date_ymd_to_serial
	[10] => convert_datetime
	[11] => convert_time
	[12] => crm_browse_contacts
	[13] => crm_common_subjects
	[14] => crm_get_clients
	[15] => crm_get_contact
	[16] => crm_get_contacts
	[17] => crm_get_history
	[18] => crm_get_history_record
	[19] => crm_get_latest_balance
	[20] => crm_get_projects
	[21] => crm_get_recent_activity
	[22] => crm_get_res_uses
	[23] => crm_get_result_code_data
	[...] => etc....

If you have questions or comments about this snippet of diagnostic PHP — or if you have some of your own diagnostic PHP to share — feel free to leave a comment.
