Syntax: kernel_getCaller([int $depth])

Get the function name that called the current function

Parameters

Optional depth
Specify how much we should go deeper. For example, if we want to get the parent of the function that called the current one, we can use 1. We could also get the parent of the parent by using 2.

Return values

Examples:

Show the caller function name

function test() {
test2();
}
function test2() {
echo kernel_getCaller(); // Will show 'test'
}

Get and show the parent function name

function parent() {
test();
}
function test() {
test2();
}
function test2() {
$parent = kernel_getCaller(1);
echo $parent; // Will show "parent"
}
