[PHP] Problems with Linux PHP

[Liam Gibbs]

I'm having a couple of problems while porting some software from Lynx OS to Linux. 
Here they are:

1. The encryption method seems to be different. Does anyone know the salt to use in 
the crypt() function in Linux?

2. Also, I seem to not be able to popen() in Linux. I get a file pointer which is 
blank. Does anybody know why?

Thanks in advance,

Liam
