How to use array_combine along with str_replace in PHP [duplicate]

Question

I am doing some array combine in php. But while combining/mapping the key of one array to value of another array i want to do some string replace in the value of the array which is going to be combined. How to use str_replace along with array_combine in php. Mostly without forloop.

Eg:

$a1 = array("35","37","43");
$a2 = array("Testing's", "testing's", "tessting's");

Normal combine is like below, (i.e) removing ' in those string while combine.

$a3 = array_combine($a1, $a2);

Output i want is like below,

array(
    35 => "Testing",
    37 => "testing",
    43 => "tessting"
)

str_replace() will happily receive an array.

Then after combining them, you could use array_map on the resultant array:

$a3 = array_map(function($e){
    return str_replace("'s", '', $e);
}, array_combine($a1, $a2)); // anonymous function PHP 5.4 or greater

You can do that :

function cust_replace($n)
    {
        return  str_replace("'s","",$n);
    }
    $a1 = array("35","37","43");
    $a2 = array("Testing's", "testing's", "tessting's");
    $a3 = array_map("cust_replace",array_combine($a1, $a2));
    print_r($a3);

If you want to make it more generic, you can add another parameter to cust_replace - the "needle" you want to replace.
