PHP PHP 8.1.0 GA Stable Release!

PHP 8.1.0 GA stable release is available now. Official announcement will be coming soon but I can see it's already released on PHP official Github release page at Release php-8.1.0 · php/php-src and that is where Centmin Mod's PHP-FPM installs get their PHP versions from. I've posted PHP 8.1.0 vs 8.0.13 vs 7.4.26 vs 7.3.33 vs 7.2.34 benchmarks as well.

This means Centmin Mod 123.09beta01 and higher users can upgrade and test PHP 8.1.0 GA stable release right now. All you need to do is run cmupdate command within SSH for your Centmin Mod server to update it to support PHP 8.1.0 GA stable release and then run centmin.sh menu option 5 to update PHP by specifying the PHP version = 8.1.0.

If you don't do cmupdate, then specifying PHP version 8.1.0 actually will pull the master branch of PHP via Git instead which is not what you want. So make sure to run cmupdate before centmin.sh menu option 5

Detected PHP 8.1 branch.
You can compile Zend OPcache (Zend Optimizer Plus+) support
as an alternative to using APC Cache or Xcache cache.
But Zend OPcache only provides PHP opcode cache and
DOESN'T do data caching, so if your web apps such as Wordpress,
Drupal or vBulletin require data caching to APC or Xcache,
it won't work with Zend OPcache.

Do you want to use Zend OPcache [y/n] ? y

 

When you log into your Centmin Mod installs, you may see this if you have set in persistent config file /etc/centminmod/custom_config.inc the variable to enable PHP version checks. This isn't enabled by default right now though.

You can also check latest PHP version for each PHP branch using getphpver command

Code (Text):

getphpver 81
8.1.0

getphpver 74
7.4.26

getphpver 73
7.3.33

Or get all latest PHP versions for each branch!

Code (Text):

getphpver

7.3.33
7.2.34
7.1.33

5.6.40
5.5.38

 

Indeed.

I've posted PHP 8.1.0 vs 8.0.13 vs 7.4.26 vs 7.3.33 vs 7.2.34 benchmarks as well

 

Also here's the PHP 8.1 branch bug tracker to check what bugs are being reported.

If you're testing your PHP apps for PHP 8.1 compatibility, with Centmin Mod LEMP stack, you can check the PHP error logs for clues too at /var/log/php-fpm/www-php.error.log. I updated my test server to PHP 8.1.0 and with some Wordpress sites on there, I see a lot of PHP Deprecated errors for Wordpress at least in /var/log/php-fpm/www-php.error.log

You can use a command line below to check last 100 lines of the PHP error log and print out a unique list of errors from the 4th field onwards (removing date/timestamp from 1st to 3rd fields)

Code (Text):

tail -100 /var/log/php-fpm/www-php.error.log | awk '{print substr($0, index($0, $4))}' | sort -u

If that is empty, then try the below extended inspection commands to take into account www-php.error.log logrotation which rotates out the logs and empties out the www-php.error.log and saves previous with date timestamp and may use gzip or zstd compression.

For gzip compression based logrotation, you can view all PHP errors with date and timestamp. Remember this will include all errors even previous fixed instead of just current log at /var/log/php-fpm/www-php.error.log. If you have more than 1 CPU thread on server, Centmin Mod will also setup multi-threaded zcat for faster processing - so replace zcat command with pzcat.

Code (Text):

zcat -f $(find /var/log/php-fpm/ -type f -name "www-php.error.log*" -exec ls -1rt "{}" +;)

For gzip compression based logroation, you can view all unique PHP errors without date and timestamp. Remember this will include all errors even previous fixed instead of just current log at /var/log/php-fpm/www-php.error.log. If you have more than 1 CPU thread on server, Centmin Mod will also setup multi-threaded zcat for faster processing - so replace zcat command with pzcat.

Code (Text):

zcat -f $(find /var/log/php-fpm/ -type f -name "www-php.error.log*" -exec ls -1rt "{}" +;) | awk '{print substr($0, index($0, $4))}' | sort -u

You can also narrow down to last 168hrs of logs with find option = -newermt "-168 hours" - just be aware the command will hang if you have no logs newer than 168hrs or whatever hours you set as awk and sort won't have anything to process. So just hit CTRL+C to abort.

Code (Text):

zcat -f $(find /var/log/php-fpm/ -type f -name "www-php.error.log*" -newermt "-168 hours" -exec ls -1rt "{}" +;) | awk '{print substr($0, index($0, $4))}' | sort -u

For zstd compression based logrotation, you can view all PHP errors with date and timestamp. Remember this will include all errors even previous fixed instead of just current log at /var/log/php-fpm/www-php.error.log

Code (Text):

zstdcat -f $(find /var/log/php-fpm/ -type f -name "www-php.error.log*" -exec ls -1rt "{}" +;)

For zstd compression based logroation, you can view all unique PHP errors without date and timestamp. Remember this will include all errors even previous fixed instead of just current log at /var/log/php-fpm/www-php.error.log

Code (Text):

zstdcat -f $(find /var/log/php-fpm/ -type f -name "www-php.error.log*" -exec ls -1rt "{}" +;) | awk '{print substr($0, index($0, $4))}'| sort -u

You can also narrow down to last 168hrs of logs with find option = -newermt "-168 hours" - just be aware the command will hang if you have no logs newer than 168hrs or whatever hours you set as awk and sort won't have anything to process. So just hit CTRL+C to abort.

Code (Text):

zstdcat -f $(find /var/log/php-fpm/ -type f -name "www-php.error.log*" -newermt "-168 hours" -exec ls -1rt "{}" +;) | awk '{print substr($0, index($0, $4))}'| sort -u

 

Means your PHP apps are perfect and compatible with whatever PHP version you're using so you have no errors maybe. Usually, you won't have PHP errors if all is working well. With PHP 8.1, I got heaps related to Wordpress heh

ls -lAhrt /var/log/php-fpm/ | grep 'www-php.error.log'

FYI, looks like PHP Composer isn't working well with PHP 8.1 either PHP 8.1 composer update fails with Segmentation fault (core dumped) · Issue #10317 · composer/composer
