PHP officially released PHP 7.1.27, PHP 7.2.16, PHP 7.3.3, these three versions of PHP can be downloaded from the PHP official website.
According to the official update log, PHP 7.2 and 7.3 mainly fix database connection problems, while PHP 7.1 fixes several null pointers, memory overflows and uninitialization problems.
It is worth noting that PHP has previously issued a message reminding users who are still using PHP 7.1 to upgrade as soon as possible because the following versions of PHP 7.1 have been discontinued in January this year if the site continues to use these old versions of PHP is likely to be attacked.
Currently, PHP officially supports three versions, namely PHP 7.1, PHP 7.2 and PHP 7.3, and PHP 7.1 will stop supporting on December 1, 2019. Therefore, the official currently recommends users to migrate to PHP 7.2 or higher.
However, at this stage, PHP 7.0 and below still occupy more than 3/4 of the PHP website, so for this part of the user, it is necessary to upgrade PHP 7.2 or higher as soon as possible.
