RE: [PHP] Self Destruct code

[snip] I have a funny request; I wrote a system for a client and am rather concerned that I am not going to receive payment for the work done. They want me to hand over the code before they are willing to pay, so basically I will be left at their mercy; if they don't pay, they will still have a working version of the system... So, is there any way I can inconspicuously code in some boo-boo's that are time related etc. Something that will bomb the mysql tables or break some code if it is not "unlocked" within a month etc. I'm not sure if people out tjere might have existing safeguard tools etc, so I'm open for suggestions. [/snip] You could try something like this; if(date == '30 days from now'){ if(unlock code <> 'the unlock code'){ Do stuff to disable code, set variables to odd values, drop tables, whatever; Do stuff to send e-mail to offending party; } } HTH!
