If you want to decode GSM-7 bit encoding in PDU from modem, you can use this code. <?php function gsm_decode($hex){ for($i = 0; $i < intdiv(strlen($hex), 2); $i += 2){ list($hex[$i], $hex[$i + 1], $hex[strlen($hex) - $i - 2], $hex[strlen($hex) - $i - 1]) = [ $hex[strlen($hex) - $i - 2], $hex[strlen($hex) - $i - 1], $hex[$i], $hex[$i + 1] ]; } $texts = ''; $bits = gmp_strval(gmp_init($hex, 16), 2); $len = strlen($bits); if($len % 7 != 0){ $bits = str_pad($bits, $len + 7 - ($len % 7), '0', STR_PAD_LEFT); } foreach(str_split($bits, 7) as $part){ $texts = hex2bin(str_pad(dechex(bindec($part)), 2, '0', STR_PAD_LEFT)) . $texts; } return $texts; } ?> ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 109.110.67.149) ---- Manual Page -- https://php.net/manual/en/function.base-convert.php Edit -- https://main.php.net/note/edit/129538 Del: integrated -- https://main.php.net/note/delete/129538/integrated Del: useless -- https://main.php.net/note/delete/129538/useless Del: bad code -- https://main.php.net/note/delete/129538/bad+code Del: spam -- https://main.php.net/note/delete/129538/spam Del: non-english -- https://main.php.net/note/delete/129538/non-english Del: in docs -- https://main.php.net/note/delete/129538/in+docs Del: other reasons-- https://main.php.net/note/delete/129538 Reject -- https://main.php.net/note/reject/129538 Search -- https://main.php.net/manage/user-notes.php
