Bug #14819 Updated: str_replace used with serialize

ID: 14819 User updated by: voltaic@thcnet.net Reported By: voltaic@thcnet.net Old Status: Feedback Status: Open Bug Type: Strings related Operating System: Linux PHP Version: 4.0.5 New Comment: I'm truly sorry. I found that the error was in the database library I was using to take the serialized string and save it in a database, although I'm not clear on why changing the order of operations fixed it (but that's not your job to fix!). Please cancel/close this faulty bug report and chastise me thoroughly.

Does this example work for you? If it does could you please provide a complete example that produces incorrect output. ------------------------------------------------------------------------ [2002-01-04 20:55:32] voltaic@thcnet.net Here are my configuration options: './configure' '--prefix=/usr/local' '--with-apache=/usr/local/src/Apachetoolbox-1.5.19/apache_1.3.19' '--enable-exif' '--enable-memory-limit=yes' '--enable-track-vars' '--with-calendar=shared' '--enable-safe-mode' '--enable-magic-quotes' '--enable-trans-sid' '--enable-wddx' '--enable-ftp' '--with-mysql' '--with-mysql=/usr/local/mysql' '--with-openssl' ------------------------------------------------------------------------ [2002-01-03 03:56:56] sander@php.net Status -> feedback ------------------------------------------------------------------------ [2002-01-03 01:28:09] georg@php.net Just tested it with 4.0.6 and 4.1.0 All seems to be ok. Can you send me your configuration options? ------------------------------------------------------------------------ [2002-01-02 23:49:09] voltaic@thcnet.net Two lines like this: $myarray[ 2 ] = str_replace( "'", "", $mystring ); $myserial = serialize( $myarray ); produce a serialized array in $myserial but it contains the wrong length or sometimes the wrong value for the string I inserted. It sometimes deletes the "'" and the following character, sometimes deletes just the "'" but has the wrong length of the string encoded in the serialized variable. An example of $myserial would be: a:3:{i:0;s:2:"s1";i:1;s:2:"s2";i:2;s:5:"dont";} Which encodes the wrong length for the final string. It works correctly when I break it into three lines: $mystring = str_replace( "'", "", $mystring ); $myarray[ 2 ] = $mystring; $myserial = serialize( $myarray ); An example of $myserial would be: a:3:{i:0;s:2:"s1";i:1;s:2:"s2";i:2;s:4:"dont";} Which encodes the correct length for the final string. This only appears to happen if there is a str_replace match in the string. If there is no match for the str_replace function, the glitch doesn't seem to appear. Thanks. ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=14819&edit=1
