Documentation​

$warning() is an alias of $warn().

Use it for the same non-fatal warning behavior as $warn(): it records a warning diagnostic, can write to the configured logger, and allows evaluation to continue. This helper belongs to Diagnostics And Errors.

It emits the same warning diagnostic entry with code F5320, records the same executionId, uses the configured logger's warn() method when logging is enabled, and returns undefined. Choose whichever name reads better in your mapping; there is no behavioral difference between $warning() and $warn().
