TalkPHP - View Single Post - how to delete an element from an array without knowing its index position

I prefer that way using array_diff. It is a handy function. Otherwise either array_keys or array_search works just as well as one another.

Was it coincidence that your array outputs as ABBA?

One thing somebody might want though is to rebuild the indexes once some items have been removed. Therefore all the indexes now increment nicely again.

php Code:

$array  = array('a', 'b', 'c', 'd', 'c', 'b', 'a');
$remove = array('c', 'd', 'f', 'Bleh'); // or just, 'c'
$array  = array_diff($array, (array) $remove);
$array = array_values($array); // restores the indexes
print_r($array);
