替换无效字符

Question

I would like to replace some invalid characters, I have an array that contains the correspondences:

$map = array(
    "à" => "a",
    "è" => "e",
    "ì" => "i",
    "ò" => "o",
    "ù" => "u"
);

I wanted to use the function str_replace($pattern, $replacement, $string) but I can't come to a conclusion. How can I proceed?

Answer 1

The solution I've found is to use the function strtr(string $str, array $arr).

Having an array, like the one mentioned above:

$map = array(
    "à" => "a",
    "è" => "e",
    "ì" => "i",
    "ò" => "o",
    "ù" => "u"
);

I just do this:

$string = "àaaaàèììkkekeou";
$new_string = strtr($string, $map);

With the result: $new_string -> "aaaaaeiikkekeou"

For details on the function: strtr()
