<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>General: Ensure the arguments passed to `implode()` are in the correct order.
The `implode()` function accepts two. parameters, `$glue` and `$pieces`. For historical reasons, these parameters have been accepted in any order, though it was recommended that the documented order of `$glue, $pieces` be used.
Starting in PHP 7.4, specifying the parameters in the reverse order will trigger a deprecation notice with the plan to remove this tolerance in PHP 8.0.
This change fixes the occurrences of reversed arguments in Core with the exception of those contained in included external libraries. These will be handled separately.
Props jrf, jorbin.
