Security PHP 7.3.5, 7.2.18, 7.1.29 Security Updates & Backported fixes PHP 5.6/7.0

PHP has released security updates for PHP 7.1.29, 7.2.18 and 7.3.5 versions. They have also changed the php.net download mirroring system they had to using a HTTPS secured CDN system (details here). The change in php.net download system, means that Centmin Mod 123.08stable and 123.09beta01 users need to update their Centmin Mod local server code BEFORE they run centmin.sh menu option 5 to update their PHP versions.

PHP Releases

• PHP 7.3.5 - latest newest PHP major branch with best performance. Centmin Mod tests at PHP 7.3 vs 7.2 vs 7.1 vs 7.0 (PHP-FPM) Benchmarks. Centmin Mod 123.09beta01 and newer supported only.
  • PHP 7.3 Bug Tracker
  • PHP 7.2 PECL Extension Status
  • What’s New in PHP 7.3 (RC Now Available at Kinsta)
  • WordPress and PHP 7.3
• PHP 7.2.18 - latest fully supported maintenance + security updates in PHP 7.2 branch. Centmin Mod 123.09beta01 and newer supported only.
• PHP 7.1.29 - last maintenance release in PHP 7.1 branch, only security updates until December 2019. Centmin Mod 123.09beta01 and newer supported only. Centmin Mod 123.08stable may work but not all PHP extension routines may work so your mileage may vary.
• PHP 7.0.33 & 5.6.40 are EOL as security and maintenance updates have ended. However, I have backported the PHP 7.1.29 security fixes to PHP 7.0.33 and 5.6.40 for Centmin Mod 123.09beta01 and newer branches at least.

Updating PHP On Centmin Mod LEMP Stacks

Detected PHP 7.3 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

*************************************************
* Zend Optimizer Plus OPcache configured
*************************************************

PHP 7+ detected which uses newer mysqlnd
or PDO MySQL extensions and removed the
legacy mysql extension. You can optionally
re-add the removed legacy mysql extension
to PHP 7+ by answering yes to next question
Only answer yes if you know for sure you
have very old web scripts which need mysql
legacy extension re-added. Otherwise answer
no which is recommended for best stability

Re-add legacy mysql extension to PHP 7+ [y/n] ? n
