If your calling method in a class has a callback function as a parameter such as usort() or array_walk() you need to call the callback function in the correct scope or php will not find it.
If your using array_walk() within a class method then you need to define the callback this way.
class SomeClass {
function doIt() {
array_walk($someArr,array($this,"someFunc"));
}
function someFunc() {
}
}
$this refers to the container SomeClass class.
If someFunc() is a static function in the class then do this way.
array_walk($someArr,array(__class__,"someFunc"));
