Thx Psycho! and sorry to have posted in the wrong forum earlier...

Hi guys Since I'm not that good with regex I'm doing this quite the lame way ... <?php $string="[0:1]={1967,1968}"; $regex="#([[](.*)[]]=)#e"; $output=preg_replace($regex, '', $string); print ( $output . "<br/>" ); $search=array('{', '}'); $output=str_replace($search, "", $output); print ( $output ); ?> How can I do this in one pass using regex only? Thx in advance!

Hi MadTechie Thanks for replying! Actually I've solved my problem of outputting the data with: for ($n=0; $n < strlen($buf); $n++) { printf("%02X\r\n", bin2hex($buf[$n])); } Now I'm having what seems to be an alignment problem... :-\ This code: $header ="\x01\x00\x00\x00"; // header $datalength ="\x00\x00\x00\x08"; // data length $codecid ="\x0A"; // codec ID $nrecs ="\x01"; // # of recs // garmin avl data $DLE ="\x10"; // DLE $packetid ="\xA1"; // packet id (161) $size_app_payload ="\x02"; // size_app_payload $fmi_packet_id = reverse_endianess_short (0x0001); // fmi packet id $checksum= $packetid+$size_app_payload+$fmi_packet_id; $checksum = -$checksum; $checksum &= 0xff; $ETX="\x03"; $buf=""; $buf=$header.$datalength.$codecid.$nrecs.$DLE.$packetid.$size_app_payload.$fmi_packet_id.$checksum.$DLE.$ETX.$nrecs; // crc16 $crc16=0; $garminAVLData=array(); $garminAVLData[]=$DLE; $garminAVLData[]=$packetid; $garminAVLData[]=$size_app_payload; $garminAVLData[]=$fmi_packet_id; $garminAVLData[]=$checksum; $garminAVLData[]=$DLE; $garminAVLData[]=$ETX; foreach ($garminAVLData as $val) { $crc=crc16($val, $crc16); } //$crc16 = pack("N", bin2hex($crc16)); $buf.=$crc16; printf("Len: %d - IP: %s\r\n", strlen($buf), $ip); for ($n=0; $n < strlen($buf); $n++) { printf("%02X\r\n", bin2hex($buf[$n])); } Outputs this: 01 00 00 00 00 00 00 08 00 01 0A 00 02 01 00 1E 0A 03 01 1E One thing that pops to view is the wrong order for $codecid and $nrecs ... The other is what I think are alignment issues... What can I do to have a byte be a byte in $buf (IOW serialize the data)? Already thankful for any help you can spare, Best regards, Pedro Doria Meunier

Hi All, Coming from the C# world I'm in a bit of pickle here trying to handle binary data and sending it to a socket... Here's what I'm trying to do: $header ="\x01\x00\x00\x00"; // header $datalength ="\x08"; // data length $codecid ="\x0A"; // codec ID $nrecs ="\x01"; // # of recs // garmin avl data $DLE ="\x10"; // DLE $packetid ="\xA1"; // packet id (161) $size_app_payload ="\x02"; // size_app_payload $fmi_packet_id = reverse_endianess_short (0x0001); // fmi packet id $checksum= $packetid+$size_app_payload+$fmi_packet_id; $checksum = -$checksum; $checksum &= 0xff; $ETX="\x03"; $buf=""; $buf=$header.$datalength.$codecid.$nrecs.$DLE.$packetid.$size_app_payload.$fmi_packet_id.$checksum.$DLE.$ETX."\x01"; First question: Is this the right way to construct the buffer? First difficulty: print the $buf contents as to check it out... This for ($n=0; $n < strlen($buf); $n++) { printf("%02X\r\n", $buf[$n]); } Only outputs zeroes... Any pointers highly appreciated...
