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. Previous Comments: ------------------------------------------------------------------------ [2004-12-28 21:57:50] phpbug at tore dot cc 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. ------------------------------------------------------------------------ [2004-12-28 19:19:36] [EMAIL PROTECTED] I don't understand what your script is doing, please come up with a trivial script instead of those loops. ------------------------------------------------------------------------ [2004-12-28 18:38:55] phpbug at tore dot cc My configuration: ./configure --with-apxs=/opt/csw/apache/bin/apxs --with-mod_charset --with-openssl=/opt/csw --enable-ftp --with-imap-ssl --with-jpeg=/usr/csw/lib --with-mysql=/opt/sfw/mysql --with-pgsql --enable-mbstr-enc-trans --enable-mbstring --enable-mbregex --with-tiff=/usr/sfc/lib --enable-inline-optimization --with-imap=/mnt/slask/src/imap-2002 --with-java=/usr/j2se --with-ming=/usr/local --with-orc8=/opt/oracle --with-gettext --with-xml --with-dom --with-zlib --enable-cli --enable-zend-multibyte --with-mod_charset --enable-gd-jis-conv --disable-libxml ------------------------------------------------------------------------ [2004-12-28 18:36:13] phpbug at tore dot cc Description: ------------ I have discoverd that a large amount of the php-scripts are using 'strlen' to count length of arbitrary strings. strlen can not cope with arbitrary strings! Code like will only show garbage values: $a = fread($binaryfile,$count); print strlen($a) . " number of bytes is read from the binary file"; Reproduce code: --------------- <?php $s=''; print "<html>\n"; for($i=142;$i<256;$i++){ $s.=pack("C",$i); $result = count_chars($s, 0); $l=0; for ($j=0; $j < 256; $j++) { $l+=$result[$j]; } print "<br>The variable s has the length: " . strlen($s) . " (actual length) " . $l . "</br>\n"; } print "</html>\n"; ?> Expected result: ---------------- The variable s has the length: 1 (actual length) 1 The variable s has the length: 1 (actual length) 2 The variable s has the length: 2 (actual length) 3 The variable s has the length: 3 (actual length) 4 The variable s has the length: 4 (actual length) 5 The variable s has the length: 5 (actual length) 6 The variable s has the length: 6 (actual length) 7 The variable s has the length: 7 (actual length) 8 The variable s has the length: 8 (actual length) 9 The variable s has the length: 9 (actual length) 10 The variable s has the length: 10 (actual length) 11 The variable s has the length: 11 (actual length) 12 . . . The variable s has the length: 64 (actual length) 111 The variable s has the length: 65 (actual length) 112 The variable s has the length: 65 (actual length) 113 The variable s has the length: 66 (actual length) 114 Actual result: -------------- The variable s has the length: 1 (actual length) 1 The variable s has the length: 2 (actual length) 2 The variable s has the length: 3 (actual length) 3 The variable s has the length: 4 (actual length) 4 The variable s has the length: 5 (actual length) 5 The variable s has the length: 6 (actual length) 6 The variable s has the length: 7 (actual length) 7 The variable s has the length: 8 (actual length) 8 The variable s has the length: 9 (actual length) 9 The variable s has the length: 10 (actual length) 10 The variable s has the length: 11 (actual length) 11 The variable s has the length: 12 (actual length) 12 . . .
