changing type of variable

[Anon]

How could I change a strin into a number?

I have avariable set to 10 from a file and I want to use it in an equation, butI don't know if I can use a string in an equation. I am not in a place to test it out, therefore, I must come here.

Thank you,
Fahhem

Go ahead: if you use a string like "10" in a place where PHP expects an integer, it will convert it into an integer "54"+"10" equals 64, not "5410" - that's "54"."10".

There's a section in the manual on this called "Type Juggling".

If you want to be certain that the value of $var is treated as an integer, you can insist on it by referring to it as (integer)$var. Often this is more for documentary purposes than any requirement by the language.
