[RESOLVED] Subtract one array values from another

[zzz]

I have two arrays:

$allValues = array('a', 'b', 'c', 'd', 'e');
$usedValues = aarray('a', 'c', 'e');

How do I create third a that will include values from $allValues minus values in $usedValues?

[zzz]

I think array_diff should do...

[zzz]

Oops, my real life code is a bit more complicated and I always get lost in arrays...

Here's how my array against ($usedValues) which I need to compare against look:

print_R($usedValues); 

//WILL RETURN
//Array ( [0] => Array ( [name] => a [size] => 20136) [1] => Array ( [name] => c [size] => 15447)  [2] => Array ( [name] => e [size] => 15447))

Clearly

$arrayDiff = array_diff($allValues, $usedValues);

won't work... Tried but without success

$arrayDiff = array_diff($allValues, $usedValues[$key]['name']);

Not sure if this is your problem but...

$usedValues = aarray('a', 'c', 'e');

Has a typo on array.

$usedValues = array('a', 'c', 'e');

oops, sorry... I was just typing and made a typo.

My main problem is that I don't know how to get the difference when the arrays that are so different formatted?

Found this...

<?php
   $array1 = array("OH" => "Ohio", "CA" => "California", "HI" => "Hawaii");
   $array2 = array("50" => "Hawaii", "CA" => "California", "OH" => "Ohio");
   $array3 = array("TX" => "Texas", "MD" => "Maryland", "KS" => "Kansas");
   $diff = array_diff_assoc($array1, $array2, $array3);
   print_r($diff);
?>

I've see this but I can't seem to be able to get it to work. My array that I generate is in the following format:

print_r($usedValues);

//WILL RETURN
//Array ( [0] => Array ( [name] => a [size] => 20136) [1] => Array ( [name] => c [size] => 15447)  [2] => Array ( [name] => e [size] => 15447)) 

[zzz]

still stuck, need help with syntax

I think I've got it. I had to create a simple array for $usedValues.
