PHP 4.0 Bug #5889: pack() does not take arrays

From: tomwk@audiogalaxy.com Operating system: Redhat Linux PHP version: 4.0.1pl2 PHP Bug Type: Feature/Change Request Bug description: pack() does not take arrays 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
