Bug Type: Scripting Engine problem
Operating System: All
PHP Version: 4CVS-2004-01-14 (stable)
New Comment:
As PHP is a typeless language, this behaviour is expected. Please take
a look at this extended version of your script:
var_dump((string)'foo', strlen('foo')); // 3
var_dump((string)true, strlen(true)); // 1
var_dump((string)false, strlen(false)); // 0
var_dump((string)array('foo', 'bar'), strlen(array('foo', 'bar'))); //
5

Description:
------------
strlen will return a value for boolean types as well as a consitent
value of 5 for an array.
Reproduce code:
---------------
<?php
var_dump(strlen('foo')); // 3
var_dump(strlen(true)); // 1
var_dump(strlen(false)); // 0
var_dump(strlen(array('foo', 'bar'))); // 5
?>
Expected result:
----------------
string foo = int(3)
bool true = int(-1)
bool false = int(-1)
array('foo', 'bar') = int(-1)
Actual result:
--------------
string foo = int(3)
bool true = int(1)
bool false = int(0)
array('foo', 'bar') = int(5)
