+; Enable zendopcache zend extension module
+zend_extension=@extensiondir@/opcache.so
+
+; OPcache On/Off switch. When set to Off, code is not optimized.
+; (default "1")
+opcache.enable = 1
+
+; The OPcache shared memory storage size.
+; The amount of memory for storing precompiled PHP code in Mbytes.
+; (default "64")
+opcache.memory_consumption = 64
+
+; The amount of memory for interned strings in Mbytes.
+; (default "4")
+opcache.interned_strings_buffer = 4
+
+; The maximum number of keys (scripts) in the OPcache hash table.
+; The number is actually the first one in the following set of prime numbers
+; that is bigger than the one supplied: { 223, 463, 983, 1979, 3907, 7963,
+; 16229, 32531, 65407, 130987 }. Only numbers between 200 and 100000 are
+; allowed.
+; (default "2000")
+opcache.max_accelerated_files = 2000
+
+; The maximum percentage of "wasted" memory until a restart is scheduled.
+; (default "5")
+opcache.max_wasted_percentage = 5
+
+; When this directive is enabled, the OPcache appends the current working
+; directory to the script key, thus eliminating possible collisions between
+; files with the same name (basename). Disabling the directive improves
+; performance, but may break existing applications.
+; (default "1")
+opcache.use_cwd = 1
+
+; When disabled, you must reset the OPcache manually or restart the webserver
+; for changes to the filesystem to take effect. The frequency of the check is
+; controlled by the directive "opcache.revalidate_freq".
+; (default "1")
+opcache.validate_timestamps = 1
+
+; How often (in seconds) to check file timestamps for changes to the shared
+; memory storage allocation. ("1" means validate once per second, but only once
+; per request. "0" means always validate)
+; (default "2")
+opcache.revalidate_freq = 2
+
+; Enables or disables file search in include_path optimization.
+; If the file search is disabled and a cached file is found that uses the same
+; include_path, the file is not searched again. Thus, if a file with the same
+; name appears somewhere else in include_path, it won't be found. Enable this
+; directive if this optimization has an effect on your applications. The
+; default for this directive is disabled, which means that optimization is
+; active.
+; (default "0")
+opcache.revalidate_path = 0
+
+; If disabled, all PHPDoc comments are dropped from the code to reduce the size
+; of the optimized code. Disabling "Doc Comments" may break some existing
+; applications and frameworks (e.g. Doctrine, ZF2, PHPUnit)
+; (default "1")
+opcache.save_comments = 1
+
+; If disabled, PHPDoc comments are not loaded from SHM, so "Doc Comments" may
+; be always stored (save_comments=1), but not loaded by applications that don't
+; need them anyway.
+; (default "1")
+opcache.load_comments = 1
+
+; If enabled, a fast shutdown sequence is used for the accelerated code. The
+; fast shutdown sequence doesn't free each allocated block, but lets the Zend
+; Engine Memory Manager do the work.
+; (default "0")
+opcache.fast_shutdown = 0
+
+; Allow file existence override (file_exists, etc.) performance feature.
+; (default "0")
+opcache.enable_file_override = 0
+
+; A bitmask, where each bit enables or disables the appropriate OPcache passes
+; (default "0xffffffff")
+opcache.optimization_level = 0xffffffff
+
+; Enable this hack as a workaround for "can't redeclare class" errors.
+; The OPcache stores the places where DECLARE_CLASS opcodes use inheritance
+; (These are the only opcodes that can be executed by PHP, but which may not be
+; executed because the parent class is missing due to optimization). When the
+; file is loaded, OPcache tries to bind the inherited classes by using the
+; current environment. The problem with this scenario is that, while the
+; DECLARE_CLASS opcode may not be needed for the current script, if the script
+; requires that the opcode at least be defined, it may not run. The default for
+; this directive is disabled, which means that optimization is active. In
+; php-5.3 and above this hack is not needed anymore and this setting has no
+; effect.
+; (default "1")
+opcache.inherited_hack = 1
+
+; The location of the OPcache blacklist file.
+; The OPcache blacklist file is a text file that holds the names of files that
+; should not be accelerated. The file format is to add each filename to a new
+; line. The filename may be a full path or just a file prefix (i.e., /var/www/x
+; blacklists all the files and directories in /var/www that start with 'x').
+; Files are usually triggered by one of the following three reasons:
+; 1) Directories that contain auto generated code, like Smarty or ZFW cache.
+; 2) Code that does not work well when accelerated, due to some delayed compile
+; time evaluation.
+; 3) Code that triggers an OPcache bug.
+; (default "")
+opcache.blacklist_filename = ""
+
+; Allows exclusion of large files from being cached. By default all files are
+; cached.
+; (default "0")
+opcache.max_file_size = 0
+
+; Check the cache checksum each N requests.
+; The default value of "0" means that the checks are disabled. Because
+; calculating the checksum impairs performance, this directive should be
+; enabled only as part of a debugging process.
+; (default "0")
+opcache.consistency_checks = 0
+
+; How long to wait (in seconds) for a scheduled restart to begin if the cache
+; is not being accessed. The OPcache uses this directive to identify a
+; situation where there may be a problem with a process. After this time period
+; has passed, the OPcache assumes that something has happened and starts
+; killing the processes that still hold the locks that are preventing a
+; restart. If the log level is 3 or above, a "killed locker" error is recorded
+; in the Apache logs when this happens.
+; (default "180")
+opcache.force_restart_timeout = 180
+
+; OPcache error_log file name. Empty string assumes "stderr".
+; (default "" which means stderr)
+opcache.error_log = ""
+
+; All OPcache errors go to the Web server log.
+; By default, only fatal errors (level 0) or errors (level 1) are logged. You
+; can also enable warnings (level 2), info messages (level 3) or debug messages
+; (level 4).
+; (default "1")
+opcache.log_verbosity_level = 1
+
+; Preferred Shared Memory back-end. Leave empty and let the system decide.
+; (default "")
+opcache.preferred_memory_model = ""
+
+; Protect the shared memory from unexpected writing during script execution.
+; Useful for internal debugging only.
+; (default "0")
+opcache.protect_memory = 0
+
+; Mapping base of shared memory segments (for Windows only). All the PHP
+; processes have to map shared memory into the same address space. This
+; directive allows to manually fix the "Unable to reattach to base address"
+; errors.
