a simple question

[Phil]

i am writing a script for php (duh), but i need to know if a command is needed for a space (not a normal space)

the line is:

$tablename = divinglog_$name;

the question is:

does there need to be any command between the _ and the variable or will that work as it is?

[Phil]

also can someone tell me what to use as a seperator?

so if the field says london-liverpool

it can be split into
london
liverpool?
