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.
