#31324 [Opn->Bgs]: function strlen miscounts

ID: 31324 Updated by: iliaa@php.net Reported By: phpbug at tore dot cc -Status: Open +Status: Bogus Bug Type: Strings related Operating System: Solaris 10 PHP Version: 5.0.2 New Comment: Sounds like either a compiler or libc bug. I cannot replicate this on my systems either. Previous Comments: ------------------------------------------------------------------------ [2004-12-29 19:13:28] phpbug at tore dot cc I might add that I tried php-5.0.3 on an intel-based solaris 10 machine and there were no problems with the strlen. ------------------------------------------------------------------------ [2004-12-29 07:34:41] phpbug at tore dot cc 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.... ------------------------------------------------------------------------ [2004-12-28 23:59:37] derick@php.net 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... ------------------------------------------------------------------------ [2004-12-28 23:40:36] phpbug at tore dot cc 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. ------------------------------------------------------------------------ [2004-12-28 23:07:29] derick@php.net 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. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
