Description:
------------
The function opcache_is_script_cached is meant to return true if a script is already cached and present in OPCache. This is failing when running in the fpm-cgi in 5.6.7.


It works when:
* called from the CLI sapi.
* in the fpm-cgi sapi in 5.6.2


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

var_dump(opcache_is_script_cached(__FILE__));
var_dump(opcache_is_script_cached(realpath(__FILE__)));

//The current file should always be present, as it is compiled and cached before being run.

Expected result:
----------------
bool(true) bool(true)

Actual result:
--------------
bool(false) bool(false)

I can not reproduce this with php-fpm (5.6 branch)

It's possible I'm doing something dumb, but I've tested this against freshly compiled versions of 5.6.2 and 5.6.7 and there does seem to be different behaviour.

File /etc/php.ini
=================

zend_extension=opcache.so

opcache.validate_timestamps=off
opcache.enable=1
memory_limit=127M


test.php
=========
<?php

var_dump(opcache_is_script_cached(__FILE__));





Configure script
================
./configure  \

I'm using the builtin webserver to test `php -S 127.0.0.1:80` and then `wget -O php5.6.2.test 127.0.0.1/test.php` and the same command with a different output filename for 5.6.7 

I'm still seeing that the file is cached according to 5.6.2 and isn't according to 5.6.7

The bug is in two parts, first the timestamp is only set if the opcache.validate_timestamps is enabled:

http://lxr.php.net/xref/PHP_TRUNK/ext/opcache/ZendAccelerator.c#1449


But then OPCache is assuming that the file is only cached if the timestamp is set to not zero.
