ID: 5889 Comment by: joshua at gmail dot com Reported by: tomwk at audiogalaxy dot com Summary: pack() does not take arrays Status: Wont fix Type: Feature/Change Request Package: Feature/Change Request Operating System: Redhat Linux PHP Version: 4.0.1pl2 Block user comment: N Private report: N New Comment: Yes, it WILL be implemented Previous Comments: ------------------------------------------------------------------------ [2004-06-14 10:49:20] [email protected] This will not be implemented. ------------------------------------------------------------------------ [2000-08-01 10:22:25] [email protected] Well, functions args work differently in perl and PHP. Maybe we need some "array" type of pack modifier, because PHP does not convert function arguments to array. Though, you can write a wrapper function using func_get_args() and func_num_args() for this. ------------------------------------------------------------------------ [2000-08-01 09:51:18] tomwk at audiogalaxy dot com I have an application that writes data across our network to another program. Most of the data consists of integer arrays. I'm currently doing this in a very simple manner, using something like this: for( $i = 0; $i < $numInts; $i++ ) { fwrite( $fd, pack( "N", $ints[ $i ] ) ); } However, this results in a very large number of calls to fwrite, which is bad for performance. I made the routine about 3 times faster by doing something like this: fwrite( $fd, pack( "N10" $ints[ $i + 0 ], $ints[ $i + 1 ], $ints[ $i + 2 ], ///.. and so on, However, it would be really great if pack could take an array as one of it's arguments. I believe this is the way Perl behaves, but when I try: $data = array( 10, 123 ); $buf = pack( "N*", $data ); $valArray = unpack( "N*", $buf ); while( list( $key, $val ) = each( $valArray ) ) { echo "$key -> $val\n"; } the only output I get is: 1 -> 1 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=5889&edit=1
