Re: string size in bytes

i need to know how many bytes are in a string example: $string = "blah"; string == how many bytes

Well, if you're willing to ignore all the unicode stuff, you can use strlen() since 1 byte = 1 character. Check that manpage to see if there's a unicode safe version.

also i need to know how to find out how fast a page renders example; page rendered in 1.114 seconds

microtime(). Call it at the beginning of your script, then at the end, and substract the two values to see how long it took.
