Description:

Hi!

Compiling files through opcache_compile_file fails with the notice even if opcache is enabled: 

PHP Notice:  Zend OPcache seems to be disabled, can't compile file in compile.php on line 8

The following lines of the zend_accelerator_module.c file seems to be the cause of the notice if I'm not mistaken.

	if (!ZCG(enabled) || !accel_startup_ok || !ZCSG(accelerator_enabled)) {
		zend_error(E_NOTICE, ACCELERATOR_PRODUCT_NAME " seems to be disabled, can't compile file");
		RETURN_FALSE;
	}

Based on my configuration, ZCG(enabled) should return true. Therefore, my guess is that either accel_startup_ok or ZCSG(accelerator_enabled) is the issue here. 

Test script:
---------------
// compile.php
<?php
  var_dump(opcache_get_status());
  var_dump(opcache_get_configuration());
  opcache_compile_file("myfile.php");
?>

I'm calling this script in command line : php -c php.ini compile.php

Actual result:
--------------
Running var_dump(opcache_get_status()) returns :

  ["opcache_enabled"]=>
  bool(false)
  ["file_cache"]=>
  string(63) "/hunt_opcache"
  ["file_cache_only"]=>
  bool(true)

Here we can see opcache_enabled is false.

Running var_dump(opcache_get_configuration()) returns the following relevant lines :

  ["directives"]=>
  array(28) {
    ["opcache.enable"]=>
    bool(true)
    ["opcache.enable_cli"]=>
    bool(true)
    ["opcache.use_cwd"]=>
    bool(true)
    ...
  }
  ["version"]=>
  array(2) {
    ["version"]=>
    string(9) "7.0.6-dev"
    ["opcache_product_name"]=>
    string(12) "Zend OPcache"
  }
}

... Here, OPcache configuration shows that OPcache is enabled.
