Version Difference

Hi all, With the following in one page: <input type=text name=document_title>"; and this in the page called: echo "$document_title"; I am receiving two different results from two different environments under some circumstances, which is causing me a massive headache. My development environment is PHP 4.0.3pl1 running on Windows 95. My live environment is 4.0.1pl2 running on a Cobalt Raq. All is well in both the above until the user enters an apostrophe, upon which the development environment nicely adds a backslash prior to it, allowing it to be saved in Mysql with no additional effort. The live environment, however, does not. I am trying to build quite an advanced system using PHP and I'm finding a number of issues with quotes and double-quotes which makes building dependable code extremely difficult and time consuming. Has anyone else had trouble getting their applications to be 100% water tight regarding user entry? Any help would be greatly appreciated - I've now spent more than one week just messing around with apostrophes in one form or another - this is only the latest of my worries - and I'm sure there are more quote related issues to come :O) Gareth Davies Progressive Business Services Ltd +44 (0) 1274 889592 Office +44 (0) 1274 889656 Fax +44 (0) 7970 733851 Mobile (24 Hour)
