Operating System: Solaris 10
PHP Version: 5.0.2
New Comment:
I have used gcc2 and gcc3 to compile.
The machine is a sparc.
The problem occurs on solaris 9 and solaris 10.
If you suspect that this is a solaris problem, can you extract the code
for 'strlen' in php. I could make some tests in C....

It still works fine for me on Linux. Which compiler did you use to
compile PHP (gcc or sun workshop), and what kind of platform do you
use? intel (32/64), sparc...

Sorry, my mistake!
It seems to work on one char long strings.
I made a better script (still avoiding loops...).
<?php
$s=pack("C*",0x8e,0x8f);
$t=pack("C*",0x8e);
$u=pack("C*",0x8e,0x8f,0x90);
print "The variable s has the length: " . strlen($s) . "\n";
print "The variable t has the length: " . strlen($t) . "\n";
print "The variable u has the length: " . strlen($u) . "\n";
?>
Result:
The variable s has the length: 1
The variable t has the length: 1
The variable u has the length: 2
The result should be:
The variable s has the length: 2
The variable t has the length: 1
The variable u has the length: 3
Since s=2 chars, t=1 char and u 3 chars long.
Lets try another test with 7 bit chars.
<?php
$s=pack("C*",0x30,0x31);
$t=pack("C*",0x30);
$u=pack("C*",0x30,0x31,0x32);
print "The variable s has the length: " . strlen($s) . "\n";
print "The variable t has the length: " . strlen($t) . "\n";
print "The variable u has the length: " . strlen($u) . "\n";
?>
Result:
The variable s has the length: 2
The variable t has the length: 1
The variable u has the length: 3
As expected. No problem with low values on the chars.

Please try using this CVS snapshot:
http://snaps.php.net/php5-STABLE-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php5.0-win32-latest.zip
Both in 4.3.10RC2, 5.0.3-dev, and 5.1.0-dev it prints as expected:
The variable s has the length: 1 (actual length) 1
So please try a snapshot.

How about:
<?php
$s=pack("C",143);
$result = count_chars($s, 0);
print "The variable s has the length: " .
strlen($s) . " (actual length) " . $result[143] .
"\n";
?>
Gives printout:
The variable s has the length: 0 (actual length) 1
The 'pack' creates a bit-string with a length of 1 char.
The 'strlen' should should recognize it as a char with length 1. As you
can see below 'strlen' does not only miscalculates the string length for
the char 143.

I don't understand what your script is doing, please come up with a
trivial script instead of those loops.
