Remove Values from Array

If you need to remove elements from an array that have a particular value(s) here’s a neat way of doing it without any looping:

    // our initial array
    $arr = Array("blue", "green", "red", "yellow", "green", "orange", "yellow", "indigo", "red");
    print_r($arr);
     
    // remove the elements who's values are yellow or red
    $arr = array_diff($arr, array("yellow", "red"));
    print_r($arr);
     
    // optionally you could reindex the array
    $arr = array_values($arr);
    print_r($arr);

This is the output from the code above:

Array ( [0] => blue [1] => green [2] => red [3] => yellow [4] => green [5] => orange [6] => yellow [7] => indigo [8] => red ) Array ( [0] => blue [1] => green [4] => green [5] => orange [7] => indigo ) Array ( [0] => blue [1] => green [2] => green [3] => orange [4] => indigo ) Thank you
