Question

How do you replace values in a string which match an entry in array with the same value but with a \ in front of it ?

$test = "Mike (D)";
$array('(',')','@','-');

As ( ) are in the array $test should equal "Mike \(D\)";

So basically replacing the item with item same item prefixed with \

Answer 1

$test      = "Mike (D)";
$find      = array('(',')','@','-');
$repalce   = array('\(','\)','\@','\-');

$newphrase = str_replace($find, $repalce, $test);
