Bug description: Variable initialization in function happens after function
call
Description:
------------
If a variable is initialized inside a function call (e.g. foo($bar,
$baz=3) ) and that parameter is a reference, then the variable cannot be
altered by the function. It works ok if the variable is initialized
outside the function call.
This bug exists in PHP 5.1.2. It does not exist in 5.0.3. I checked the
changelogs and release notes for all versions inbetween, but I did not
find anything that indicated that the language changed in this way.
Reproduce code:
---------------
function foo(&$bar) {
echo "Parameter is $bar\n";
$bar = "baz";
}
foo($woz = "abc");
echo "Woz is $woz\n";
$bliz = "abc";
foo($bliz);
echo "Bliz is $bliz\n";
Expected result:
----------------
Parameter is abc
Woz is baz
Parameter is abc
Bliz is baz
Actual result:
--------------
Parameter is abc
Woz is abc
Parameter is abc
Bliz is baz
