Question

I think questions like this are the reason why I don’t like working with PHP. The manual is good, if you can find what you are looking for. After reading through the Array Functions, I didn’t see one that provides the functionality I need.

I have an array (in my case, numerically indexed) that I want to scan for a particular value and, if it’s there, remove it. And then, when all instances of that value have been removed, I want to rearrange the array using array_values.

array_diff is what you want.

$array1 = array('a' => 'green', 'red', 'blue', 'red'); $array2 = array('b' => 'green', 'yellow', 'red'); $result = array_diff($array1, $array2); 

Result: 'blue'.
