PHP Version Gotcha

Just copied some code from a PHP 7.3+ development environment to the server running PHP 7.2

On the server I am getting this

On PHP 7.3 it runs fine

Because the line number is not listed this is how I find the problem

Find which controller is being called when you see the error
Run php -l on the PHP 7.2 against the app/Controller/PalletController.php file
Systematically go through the files. From Controller to Model to View

php -l CartonsController.php
No syntax errors detected in CartonsController.php
php -l edit_pallet_cartons.ctp
No syntax errors detected in edit_pallet_cartons.ctp
php -l ../../Model/Carton.php
PHP Parse error:  syntax error, unexpected ')' in ../../Model/Carton.php on line 85
Errors parsing ../../Model/Carton.php

Once you see the error open the file and find the line. Here the error is a trailing comma in the function call which is supported by 7.3 but not 7.2

# speed up the checking in a directory
cd app/Controller
for i in `ls *.php` ; do php -l $i ; done
