PHP Bug Type: Reflection related
Bug description: preg_replace 'subject' parameter listed as optional
Description:
------------
According to reflection the third parameter to preg_replace (subject) is
optional. Calling preg_replace without a third argument, however, issues a
warning.
This bug is similar to #45909 (filed for PHP 5.2.6 in 2008, closed), but
the output has changed since (when most of the reflection bugs were fixed
for 5.3.0).
Reproduce code:
---------------
1)
php --rf preg_replace
2)
$fn = new ReflectionFunction("preg_replace");
printf("Total: %d\nRequired: %d\n",
$fn->getNumberOfParameters(),
$fn->getNumberOfRequiredParameters()
);
Expected result:
----------------
1)
>php --rf preg_replace
Function [ <internal:pcre> function preg_replace ] {
- Parameters [5] {
Parameter #0 [ <required> $regex ]
Parameter #1 [ <required> $replace ]
Parameter #2 [ <required> $subject ]
Parameter #3 [ <optional> $limit ]
Parameter #4 [ <optional> &$count ]
}
}
2)
Total: 5
Required: 3
Actual result:
--------------
1)
>php --rf preg_replace
Function [ <internal:pcre> function preg_replace ] {
- Parameters [5] {
Parameter #0 [ <required> $regex ]
Parameter #1 [ <required> $replace ]
Parameter #2 [ <optional> $subject ]
Parameter #3 [ <optional> $limit ]
Parameter #4 [ <optional> &$count ]
}
}
2)
Total: 5
Required: 2
