Cannot convert string to int in PHP -

i'm having tough time converting value read socket connection integer. it's value tells me how many bytes going received next.

$ar = fread($client, 4); $binaryint = unpack('n', $ar); debug_to_console($binaryint); //displays 16 (as expected) $bred = fread($client, intval($binaryint)); //intval returns 1 

for reason intval evaluates 1 , can't figure out why. btw $ar variable sent integer java server have running via code sample

dout.writeint(data.length); 

thanks

edit

i got it. user2587326 below helped instead of using intval(binaryint[1]) binaryint[1].

i think reading 4-byte integer sent java program on dataoutputstream php program on socket.

first, fread($client, 4) call reads 4 bytes string, convert them array unpack(), taking 4-bytes @ time (format specifier 'n') resulting array 1 element, use:

intval($binaryint[1]) instead of intval($binaryint) obtain number.

edit: works intval too, won't hurt it.
