Question

I am trying to loop through an array and replace values that are in_array of a different array.

$array = array("username"=>"Bill", "email" => "Email Address");
$unset = array("Username","Email Address"); // Array of default values for inputs
foreach($array as $key => $value) {
    global $unset;
    if(in_array($value, $unset)) {
        $value = "-";
    }
}
print_r($array["email"]);

I want to replace the value in $array in which matches a default value to “-“. Not looking to unset and array_splice, hold the space.

Answer 1

Try this:

$array = array("username"=>"Bill", "email" => "Email Address");
$unset = array("Username","Email Address"); // Array of default values for inputs

foreach($array as &$value) {
    if(in_array($value, $unset)) {
        $value = "-";
    }
}
print_r($array["email"]);
