PHP OPcode caching on Drupal 9

Drupal is perfect and best CMS , i love it, but long time i not work with drupal bout i try and learn new generation CMS and static site generator like gatsby js, jekyll angular and more. Drupal one of my favorite for develope website project, i use drupal CMS @2012 - 2015, on 2016 i have stop to update another website, cause i'm very bussy with my job, and on 2019 i back again to learn another cms for develope website,and wow... I was very surprised by the development of technology. many significant changes and especially the emergence of the latest generation of flatfile cms to static sites generator , and for the first time I was shocked by Jekyll, how fast he was and this was a breakthrough that was really new to the generation of websites. After that, I was surprised again by the presence of Gatsby who was getting crazy in my opinion, this is really fast and even without loading. and in November 2019 I returned to learn more about the development of the website, including studying jekyll, gatsby js, angular , laravel to ionic and darts. for the beginning it was very difficult considering I had not run and made a project for a long time and in fact almost never touched with coding.and after learning it and falling asleep, I missed Drupal again. I visited the Drupal website and saw some changes from Drupal, because I missed this so I decided to install Drupal to the local host. I downloaded Drupal version 9 and installed it, but the installation did not run smoothly with the error appearing as follows:PHP OPcode caching. what to do in the initial installation of this error ?? The first step - first turn off your XAMPP engine including apache server and mysql, find and enter the php.ini file then add the following code. zend_extension=php_opcache.dll

[opcache]
; Determines if Zend OPCache is enabled
opcache.enable=1

; Determines if Zend OPCache is enabled for the CLI version of PHP
opcache.enable_cli=0

; The OPcache shared memory storage size.
opcache.memory_consumption=64

; The amount of memory for interned strings in Mbytes.
opcache.interned_strings_buffer=4

; The maximum number of keys (scripts) in the OPcache hash table.
Only numbers between 200 and 100000 are allowed.
;opcache.max_accelerated_files=2000

; The maximum percentage of "wasted" memory until a restart is scheduled.
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.
opcache.use_cwd=1

; When disabled, you must reset the OPcache manually or restart the
; webserver for changes to the filesystem to take effect.
;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)
;opcache.revalidate_freq=2

; Enables or disables file search in include_path optimization
;opcache.revalidate_path=0

; If disabled, all PHPDoc comments are dropped from the code to reduce the
; size of the optimized code.
;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.
;opcache.load_comments=1

; If enabled, a fast shutdown sequence is used for the accelerated code
;opcache.fast_shutdown=0

; Allow file existence override (file_exists, etc.) performance feature.
;opcache.enable_file_override=0

; A bitmask, where each bit enables or disables the appropriate OPcache
; passes
;opcache.optimization_level=0xffffffff

;opcache.inherited_hack=1
;opcache.dups_fix=0

; 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. 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'). Line starting with a ; are ignored (comments).
;opcache.blacklist_filename=

; Allows exclusion of large files from being cached. By default all files
; are cached.
;opcache.max_file_size=0

; Check the cache checksum each N requests.
; The default value of "0" means that the checks are disabled.
;opcache.consistency_checks=0

; How long to wait (in seconds) for a scheduled restart to begin if the cache
; is not being accessed.
;opcache.force_restart_timeout=180

; OPcache error_log file name. Empty string assumes "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).
;opcache.log_verbosity_level=1

; Preferred Shared Memory back-end. Leave empty and let the system decide.
;opcache.preferred_memory_model=

; Protect the shared memory from unexpected writing during script execution.
; Useful for internal debugging only.
;opcache.protect_memory=0


after that, update and save the php.ini file , then run your XAMPP machine again and access via localhost and Viola your Drupal installation is works , just shared about PHP OPcode caching Drupal 9 solved
