Operating system: Win32/Linux/OpenBSD
PHP version: 4.3.1
PHP Bug Type: Unknown/Other Function
Bug description: Differences between string escaping
Description:
------------
I write and test PHP scripts on WinXP with Apache 1.3.x and pre-compiled
PHP 4.3.2. Sites where I host my pages are Linux and OpenBSD running
Apache 1.3.x and PHP 4.3.1. In both cases I use MySQL. Both PHP
installations have the same configuration except for the file paths.
Program I wrote stores HTML pages in database so the text in SQL statement
has to be escaped. Under WinXP I have to write code like this:
$string = "'".addslashes($string)."'";
Under Linux and OpenBSD installations when I run the same code I get the
string escaped TWICE. I presume that the string is escaped again during
concantenation.
Reproduce code:
---------------
$string = '<IMG SRC="http://example.com/Arrow.gif">';
$string = "'".addslashes($string)."'";
// Under WinXP I get:
// <IMG SRC=\"http://example.com/Arrow.gif\">
// Under Linux & OpenBSD I get
// <IMG SRC=\\\"http://example.com/Arrow.gif\\\">
