Question

On the php manual we can read:

fwrite() returns the number of bytes written

Ok… but what kind of thing is “number of bytes written”?

Binary string? Binary number? Stream? Int?

I’m a little bit lost here.

Regards

Answer 1

From the manual:

Description

int fwrite ( resource $handle , string $string [, int $length ] )

It returns an int on success, as indicated by the type name just before the function name. It returns FALSE on error:

fwrite() returns the number of bytes written, or FALSE on error.
