Coding Standards: Replace alias PHP functions with the canonical names.

Browse Source 
Using the canonical function name for PHP functions is strongly recommended, as aliases may be deprecated or removed without (much) warning.

This replaces all uses of the following:
* `join()` with `implode()`
* `sizeof()` with `count()`
* `is_writeable()` with `is_writable()`
* `doubleval()` with a `(float)` cast

In part, this is a follow-up to #47746.

Props jrf.
See #50767.
