Deleting an element from an array in PHP

Question

Is there an easy way to delete an element from an array using PHP, such that foreach ($array) no longer includes that element?

I thought that setting it

Answer 1

If the index is specified:

$arr = ['a', 'b', 'c'];
$index = 0;    
unset($arr[$index]);  // $arr = ['b', 'c']

If the index is NOT specified:

$arr = ['a', 'b', 'c'];
$index = array_search('a', $arr); // search the value to find index
if($index !== false){
   unset($arr[$index]);  // $arr = ['b', 'c']
}

The if condition is necessary because if index is not found, unset() will automatically delete the first element of the array which is not what we want.
