Doc #80482 [NEW]: Undocumented behavior of array_walk with objects

From: php4fan at gmail dot com Operating system: all PHP version: Irrelevant Package: Documentation problem Bug Type: Documentation Problem Bug description:Undocumented behavior of array_walk with objects Description: ------------ --- From manual page: https://php.net/function.array-walk --- The documentation says that the first parameter of array_walk must be an array, but in reality it also works when passed an object, and it iterates over the properties. Also, when used on ArrayObject (which, again, is undocumented in itself), this function is affected by a dramatic bc-breaking change in 7.4 that is described in the migration guide: https://www.php.net/manual/en/migration74.incompatible.php#migration74.incompatible.spl (there's no specific mention of array_walk but I guess it falls under "etc." and "potentially others") Namely, when calling array_walk() on an array object, prior to 7.4 it would iterate over the wrapped array/object, while starting from 7.4 it iterates over the properties of the ArrayObject itself. This should be documented in From manual page: https://php.net/function.array-walk Test script: --------------- . Expected result: ---------------- .
