I’m putting out a call for those who want to help with community effort toward making FreePBX 15 work with PHP 7.3. A story ticket with sub-tasks containing specific fixes can be found at https://issues.freepbx.org/browse/FREEPBX-20203
PHP 7.3 is the standard version released in the new Debian 10 “buster” and also in the latest OS for Raspberry Pi.
Please help test the proposed patches, which should also be fully backward compatible with PHP 7.x and PHP 5.6. Please also contribute any other fixes you find and link to that ticket for easy tracking.
