+; Enable Zend OPcache extension module
+; Determines if Zend OPCache is enabled
+; Determines if Zend OPCache is enabled for the CLI version of PHP
+; The OPcache shared memory storage size.
+; The amount of memory for interned strings in Mbytes.
+; The maximum number of keys (scripts) in the OPcache hash table.
+; Only numbers between 200 and 100000 are allowed.
+; The maximum percentage of "wasted" memory until a restart is scheduled.
+; 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.
+; When disabled, you must reset the OPcache manually or restart the
+; webserver for changes to the filesystem to take effect.
+; 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)
+; Enables or disables file search in include_path optimization
+; If disabled, all PHPDoc comments are dropped from the code to reduce the
+; size of the optimized code.
+; If enabled, a fast shutdown sequence is used for the accelerated code
+; Allow file existence override (file_exists, etc.) performance feature.
+; A bitmask, where each bit enables or disables the appropriate OPcache
+; passes
+; The location of the OPcache blacklist file (wildcards allowed).
+; Each OPcache blacklist file is a text file that holds the names of files
+; that should not be accelerated.
+; Allows exclusion of large files from being cached. By default all files
+; are cached.
+; Check the cache checksum each N requests.
+; The default value of "0" means that the checks are disabled.
+; How long to wait (in seconds) for a scheduled restart to begin if the cache
+; is not being accessed.
+; OPcache error_log file name. Empty string assumes "stderr".
+; 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).
+; Preferred Shared Memory back-end. Leave empty and let the system decide.
+; Protect the shared memory from unexpected writing during script execution.
+; Useful for internal debugging only.
+; Allows calling OPcache API functions only from PHP scripts which path is
+; started from specified string. The default "" means no restriction
+; Enables and sets the second level cache directory.
+; It should improve performance when SHM memory is full, at server restart or
+; SHM reset. The default "" disables file based caching.
+; RPM note : file cache directory must be owned by process owner
+; for mod_php, see /etc/httpd/conf.d/php.conf
+; for php-fpm, see /etc/php-fpm.d/*conf
+; Enables or disables opcode caching in shared memory.
+; Enables or disables checksum validation when script loaded from file cache.
+; Implies opcache.file_cache_only=1 for a certain process that failed to
+; reattach to the shared memory (for Windows only). Explicitly enabled file
+; cache is required.
+; Validate cached file permissions.
+; Leads OPcache to check file readability on each access to cached file.
+; This directive should be enabled in shared hosting environment, when few
+; users (PHP-FPM pools) reuse the common OPcache shared memory.
+; Prevent name collisions in chroot'ed environment.
+; This directive prevents file name collisions in different "chroot"
+; environments. It should be enabled for sites that may serve requests in
+; different "chroot" environments.
