Edit Question
Title
Body
There are 2 functions involved. Search array items for a given string unset() array item if string not found $array = array("first", "second", "third", "fourth"); foreach($array as $i=> $string) { if(stristr($string, "e")) { unset($array[$i]); } } second is the array item with the character 'e'. If its unset , $array[1] would be left empty: $array[0] = "first" $array[1] = "" $array[2] = "third" $array[3] = "fourth" I want $array[1] to be removed from the array (like in array_shift() ), so that third takes the place of second and fourth the place of third : $array[0] = "first" $array[1] = "third" $array[2] = "fourth"
