php - Parse error on double quotes (but there's no error on local server)

Question

So I have the following function on my code:

/* returns a random string */
function randStr($length = 32, $chars = "abcdefghijklmnopqrstuxyvwzABCDEFGHIJKLMNOPQRSTUXYVWZ!@#$%&*()_-+=") {
//function randStr($length, $chars) {
    $validCharNumber = strlen($chars);
    for ($i = 0; $i < $length; $i++) {
        $str .= $chars[rand(0, $validCharNumber - 1)];
    }
    return $str;
}

it was working ok on my local server and some other development server that we used. But on the final server, I keep getting the following message: Parse error: syntax error, unexpected '"'

I searched on google but I couldnt get precise results because I can't use quotes to be more accurate when I'm searching about quotes.

I'm also getting the same error message on this block of code

"last_update" => Array("display" => "return toDate('$1', 'd/m/Y H:i:s');")

Where's the error? Did I miss any kind of configuration for double quotes or something?

It's php version issue. You could check your code for php versions compatibilities with online tools which allow to run code on different versions.

For example: http://3v4l.org/60NfG

Deal in '$' inside double quoted string in function argument.

I only got this error:

Notice: Undefined variable: str in D:\wamp\www\index.php on line 7

Fixed it by adding $str =''; before for loop. Everything else works fine.

My PHP Version is 5.4.12
