array_map() with multiple callback functions

[George Langley <george.langley@xxxxxxx>]

Hi all. I want to apply strtolower() AND trim() to all items in an array. But I don't see a way to call multiple callbacks with the array_map() function.
Are my two choices the following:

// 1) nesting two array_map() calls
$cleanData = array_map('trim',(array_map('strtolower',$rawData)));


// 2) call my own function with array_walk()
$cleanData = array_walk('myCleaner',$rawData);

function myCleaner($passedData){
	$cleanData = array_map('strtolower',$passedData);
	$cleanData = array_map('trim',$cleanData);
}
//(Of course, wouldn't bother with a function, just to call array_map twice...)

Just seeing if there's a better way than having to go through the array twice to apply each callback separately. Thanks,
