PHP associates with arrays to delete elements based on element values. php Arrays

The example in this article describes how to delete elements based on element values in PHP associated array. Share it with you for your reference. The details are as follows:

<? Php $ array1 = array ("a" => "green", "red", "blue", "red "); $ array2 = array ("B" => "green"); $ result = array_diff ($ array1, $ array2 ); // This is equivalent to deleting the element whose value is "green" in $ array1. Print_r ($ result);?>

There is another method that is more complex than the above, but the effect is the same:

Function removeArrayElement (& $ ar, $ val) {$ tmp = array (); foreach ($ ar as $ k =>$ arc) {if ($ arc! = $ Val) {$ tmp [$ k] = $ arc; }}$ ar = $ tmp; unset ($ tmp );}
