WAMP哈希不生成

Question

The following code is not generating an output in WAMP on windows.

Works fine on MAMP.

Guessing it's a missing module or something.

$reportHash = str_replace(
        array('+','/','='),
        array('-','_',''),
        base64_encode(file_get_contents('/dev/urandom', null, null, -1, 16)));

Answer 1

There is no /dev/urandom on Windows.

Use uniqid() for a portable random string generator or mt_rand() for a portable random number generator.
