array size in bytes

Hi,

Exists in PHP function returning array size in bytes ?
(For saving array into shared memory without serialize.)

Thnx. Roman

No.

And you could maybe write one, if it was all strings in the array, but
you're gonna be screwed when PHP 6 with Unicode comes out, cuz the
number of bytes "depends" on where you're gonna store it, in which
charset, and several other factors...

There was a thread on PHP-internals last month about the the strlen()
function should or shouldn't do for that -- and if sizeof() should or
shouldn't do something different.

You probably shouldn't be poking it into shared memory without
serializing it anyway, I don't think...

How about saving the array as a file and then do a filesize()?

Wouldn't this work?

$arraySize = strlen( implode( '', $array ));

Though, additional work would need to be done for nested arrays.

thnx,
