New Comment:
Here is the entire mbstring section of my php.ini file, I haven't
changed it from the default that comes when you download PHP.
[mbstring]
; language for internal character representation.
;mbstring.language = Japanese
; internal/script encoding.
; Some encoding cannot work as internal encoding.
; (e.g. SJIS, BIG5, ISO-2022-*)
;mbstring.internal_encoding = EUC-JP
; http input encoding.
;mbstring.http_input = auto
; http output encoding. mb_output_handler must be
; registered as output buffer to function
;mbstring.http_output = SJIS
; enable automatic encoding translation according to
; mbstring.internal_encoding setting. Input chars are
; converted to internal encoding by setting this to On.
; Note: Do _not_ use automatic encoding translation for
; portable libs/applications.
;mbstring.encoding_translation = Off
; automatic encoding detection order.
; auto means
;mbstring.detect_order = auto
; substitute_character used when character cannot be converted
; one from another
;mbstring.substitute_character = none;
; overload(replace) single byte functions by mbstring functions.
; mail(), ereg(), etc are overloaded by mb_send_mail(), mb_ereg(),
; etc. Possible values are 0,1,2,4 or combination of them.
; For example, 7 for overload everything.
; 0: No overload
; 1: Overload mail() function
; 2: Overload str*() functions
; 4: Overload ereg*() functions
;mbstring.func_overload = 0
Thanks

Could you show me the mbstring related setting (mbstring.*)
in your php.ini ?

Description:
------------
The bounds check for the offest argument in mb_strpos appears to be a
byte count rather than a character count.
In the example below, $string_ascii is 21 characters long and
$string_mb is 21 characters (53 bytes) long. In both cases the needle
appears twice, first at position 9 and secondly at position 20.
With the multibyte string example, when the offset is past the
character count of the string it would be expected to return a warning
but instead a warning is returned when offest is past the byte count.
Reproduce code:
---------------
<?php
$offsets = array(20, 21, 22, 53, 54);
$string_mb =
base64_decode('5pel5pys6Kqe44OG44Kt44K544OI44Gn44GZ44CCMDEyMzTvvJXvvJbvvJfvvJjvvJnjgII=');
$needle = base64_decode('44CC');
foreach($offsets as $i) {
echo "\n-- Offset is $i --\n";
echo "--Multibyte String:--\n";
var_dump( mb_strpos($string_mb, $needle, $i, 'UTF-8') );
echo"--ASCII String:--\n";
var_dump(mb_strpos('This is na English ta', 'a', $i));
}
?>
Expected result:
----------------
-- Offset is 20 --
--Multibyte String:--
int(20)
--ASCII String:--
int(20)
-- Offset is 21 --
--Multibyte String:--
bool(false)
--ASCII String:--
bool(false)
-- Offset is 22 --
--Multibyte String:--
Warning: mb_strpos(): Offset not contained in string. in
...\mb_strpos.php on line 9
bool(false)
--ASCII String:--
Warning: mb_strpos(): Offset not contained in string. in
...\mb_strpos.php on line 11
bool(false)
-- Offset is 53 --
--Multibyte String:--
Warning: mb_strpos(): Offset not contained in string. in
...\mb_strpos.php on line 9
bool(false)
--ASCII String:--
Warning: mb_strpos(): Offset not contained in string. in
...\mb_strpos.php on line 11
bool(false)
-- Offset is 54 --
--Multibyte String:--
Warning: mb_strpos(): Offset not contained in string. in
...\mb_strpos.php on line 9
bool(false)
--ASCII String:--
Warning: mb_strpos(): Offset not contained in string. in
...\mb_strpos.php on line 11
bool(false)
Actual result:
--------------
-- Offset is 20 --
--Multibyte String:--
int(20)
--ASCII String:--
int(20)
-- Offset is 21 --
--Multibyte String:--
bool(false)
--ASCII String:--
bool(false)
-- Offset is 22 --
--Multibyte String:--
bool(false)
--ASCII String:--
Warning: mb_strpos(): Offset not contained in string. in
...\mb_strpos.php on line 11
bool(false)
-- Offset is 53 --
--Multibyte String:--
bool(false)
--ASCII String:--

...\mb_strpos.php on line 11
bool(false)
-- Offset is 54 --
