array keys matching function

[dadamssg]

Say i have two arrays with custom keys. What would be the easiest way to write a function that would determine if all the keys in arrayOne are in arrayTwo? The example below would return false because keys 3 and 4 are missing in arrayTwo. Any help would be much appreciate. thanks!

 

<?php

$arrayOne['1'] = "adg";
$arrayOne['2'] = "a4g";
$arrayOne['3'] = "346";
$arrayOne['4'] = "etwe";

$arrayTwo['1'] = "xcb";
$arrayTwo['2'] = "acbr";
$arrayTwo['6'] = "yiy";
$arrayTwo['7'] = "mmm";
?>

If you're trying to make sure both arrays have identical keys, array_diff_keys is what you need.

or

 

if (array_keys($arrayOne) == array_keys($arrayTwo)
