Re: [PHP] Size of array in bytes
Hm, I thought about that way - technically it was indeed a way to go since I don't want to perform this action everytime but only for testing purposes (so time doesn't matter). But aren't arrays in PHP internally stored in a hash-like system which's size doesn't have to be equal to the sum of it's content? I'm more interested in how many kbytes of RAM my array is using than the size in bytes of it's content... But thank you anyway for helping me! best regards Stefan Rusterholz > Had the same problem not long ago and I didn't find a simple solution > either.

Re: [PHP] Size of array in bytes
Had the same problem not long ago and I didn't find a simple solution either. My solution at the time was the painfully slow one - walking the array and storing strlen for both key and value. Since you have a large array, this probably doesn't do for you. A faster but less accurate solution would be storing round(strlen(serialize($array))*$coefficient), where you should approximate $coefficient for your average array (the less the average array element size, the smaller the coefficient). I know, these are both rudimentary and ugly solutions but I didn't find any better - these are the solutions I considered when I had the same problem.

[PHP] Size of array in bytes
Hi I have a rather large array in my script and I was interested how much memory it uses. Is there a way to get the size of an array in bytes? BTW: I did RTFM and didn't find an accomidating function, so if there is one, please point me to it...
