Description:
------------
Setting "auto_detect_line_endings" to "on" with "ini_set" doesn't enable it, because the value's parsed as a long.

This bug has a pull request.

Test script:
---------------
<?php

ini_set("auto_detect_line_endings", "on");
var_dump(ini_get("auto_detect_line_endings"));

$filePath = __DIR__ . DIRECTORY_SEPARATOR . "auto_detect_line_endings_2.txt";
file_put_contents($filePath, "fooBar1\rfooBar2\rfooBar3");

$stdin = fopen($filePath, "r");
var_dump(fgets($stdin));

Expected result:
----------------
string(2) "on"
string(8) "fooBar1"

Actual result:
--------------
string(2) "on"
string(23) "fooBar1fooBar2fooBar3"
