Bug #15711 Updated: addslashes does not always add slashes

ID: 15711 Updated by: sander@php.net Reported By: michielu@gimo.dhs.org -Status: Closed +Status: Bogus Bug Type: Unknown/Other Function Operating System: Linux PHP Version: 4.0.6 New Comment: For the stats: both addslashes and stripslashes behave as expected. This is your problem: echo "' \' \\' \\\'"; is evaluated by PHP and becomes ' \' \' \\' which is expected behaviour as \\ means \. Previous Comments: ------------------------------------------------------------------------ [2002-02-26 05:37:10] michielu@gimo.dhs.org I checked the code and the output/input for cgi and module versions and the actual problem I am running into does not seem to be in the addslashes routine, so I am closing this bug report. Apologies to anyone that took the time to read this. ------------------------------------------------------------------------ [2002-02-25 07:01:09] michielu@gimo.dhs.org I've added verbose reports in case this report is influences by addslashes as well. the following simple test: <?php echo addslashes("' \' \\' \\\'\n"); echo stripslashes(addslashes("' \' \\' \\\'\n")); ?> (i.e.: quote, slash quote, double slash quote, triple slash quote) is expected to yield (escape each slash and each quote): \' \\\' \\\\\' \\\\\\\' ' \' \\' \\\' (ie addslashes should yield slash quote, triple slash quote, five times slash quote, seven times slash quote, stripslashes should yield quote, slash quote, double slash quote, triple slash quote). Instead, addslashes does not appear to quote properly and this is what I get: \' \\\' \\\' \\\\\' ' \' \' \\' (addslashes: slash quote, triple slash quote, triple slash quote, five times slash quote. stripslashes on this output: quote, slash quote, slash quote, double slash quote). Obviously, this makes addslashes kind-of useless if you get escaped input. Yes, my database queries will not fail and that would be the primary use of addslashes. It appears that the escaped quote of the second and third combination (double slash quote and triple slash quote) is not translated to the expected triple slash quote (i.e. an escaped slash plus an escaped quote). Here's the configure line if it is of any use: './configure' '--with-apache=../apache' '--with-mysql=/usr' '--with-openssl' '--with-zlib' '--enable-debug=no' '--enable-safe-mode=no' '--enable-discard-path=no' '--with-gd' '--with-ttf' '--enable-gd-imgstrttf' '--enable-gd-native-ttf' '--with-png-dir=/usr/lib' '--with-jpeg-dir=/usr/lib' '--enable-magic-quotes' '--enable-ftp' '--enable-memory-limit' and I disabled magic_quotes_gpc in a local .htaccess ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=15711&edit=1
