Doc #76411 [NEW]: Should state that function arguments are passed by reference if objects
From: teo8976 at gmail dot com
Operating system:
PHP version: Irrelevant
Package: Documentation problem
Bug Type: Documentation Problem
Bug description:Should state that function arguments are passed by reference if objects
Description:
------------
---
From manual page: http://www.php.net/functions.arguments
---
Where it says:
"""
By default, function arguments are passed by value (so that if the value
of the argument within the function is changed, it does not get changed
outside of the function).
"""
it should say that an exception to this are objects, which are passed by
reference.
For comparison, the documentation for the assignment operator does
specify that:
http://docs.php.net/manual/en/language.operators.assignment.php
"""
Note that the assignment copies the original variable to the new one
(assignment by value), [...]
An exception to the usual assignment by value behaviour within PHP
occurs with objects, which are assigned by reference
"""
So, the documentation for function arguments should be equally clear and
explicit.
