| 2 | Notes about the required PHP Version |
||
| 3 | ==================================== |
||
| 4 | |||
| 5 | OIDplus supports PHP 7.x and 8.x. |
||
| 6 | |||
| 867 | daniel-mar | 7 | Reasons why we currently require at least PHP 7.0: |
| 791 | daniel-mar | 8 | - Return values (e.g. "function foo(): array") (added 2020-04-06 at the database classes) |
| 9 | Note: By removing these return values (e.g. removing ": array"), you *might* be |
||
| 10 | able to run OIDplus with PHP lower than version 7.0 (not tested) |
||
| 11 | |||
| 12 | Currently we do NOT require 7.1, because some (old-)stable distros are still using PHP 7.0 |
||
| 13 | (e.g. Debian 9 which has LTS support till May 2022). |
||
| 874 | daniel-mar | 14 | |
| 15 | Therefore, we commented out following features which would require PHP >=7.1: |
||
| 791 | daniel-mar | 16 | - Nullable return values (e.g. "function foo(): ?array") |
| 17 | - void return value (e.g. "function foo(): void") |
||
| 18 | - private/protected/public consts |
||
| 19 | - In composer we cannot use the latest version of polyfill-mbstring, |
||
| 20 | because this would require PHP 7.1 |
||
| 21 | Therefore in composer.json we write: |
||
| 22 | "symfony/polyfill-mbstring": "<=1.19", |
||
| 874 | daniel-mar | 23 | the same thing with phpseclib which also now requires PHP 7.1: |
| 24 | "phpseclib/phpseclib": "<=3.0.14" |
||
| 25 | Once PHP 7.1 is OK, we can go with the latest versions again. |
||
| 26 | - In dev/vendor_update.sh we patch composer packages pulled from GitHub |
||
| 27 | to achieve PHP 7.0 compat |
