spyder Posted August 17, 2006 Share Posted August 17, 2006 Hello, I adminstrate a site which offers mp3 albums to a community.I am pretty new with php and I needed a small code which would convert all mp3 files in a directory to a .zip archive and display a download link to the archive. Also, once downloaded it deletes the zip archive. Quote Link to comment Share on other sites More sharing options...

spyder Posted August 17, 2006 Author Share Posted August 17, 2006 Thanks for the script but there is a little bug in it. As I run the test.php in my browser it gives me the following error..Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home/punjabio/public_html/music/a/zip.php on line 11I didn't modify the zip.php at all. It's just the way the author wrote it from the link that you had given me.[code]<?php/** * Class to dynamically create a zip file (archive) * * @author Rochak Chauhan */class createZip { public $compressedData = array(); public $centralDirectory = array(); // central directory public $endOfCentralDirectory = "\x50\x4b\x05\x06\x00\x00\x00\x00"; //end of Central directory record public $oldOffset = 0; /** * Function to create the directory where the file(s) will be unzipped * * @param $directoryName string * */ public function addDirectory($directoryName) { $directoryName = str_replace("\\", "/", $directoryName); $feedArrayRow = "\x50\x4b\x03\x04"; $feedArrayRow .= "\x0a\x00"; $feedArrayRow .= "\x00\x00"; $feedArrayRow .= "\x00\x00"; $feedArrayRow .= "\x00\x00\x00\x00"; $feedArrayRow .= pack("V",0); $feedArrayRow .= pack("V",0); $feedArrayRow .= pack("V",0); $feedArrayRow .= pack("v", strlen($directoryName) ); $feedArrayRow .= pack("v", 0 ); $feedArrayRow .= $directoryName; $feedArrayRow .= pack("V",0); $feedArrayRow .= pack("V",0); $feedArrayRow .= pack("V",0); $this -> compressedData[] = $feedArrayRow; $newOffset = strlen(implode("", $this->compressedData)); $addCentralRecord = "\x50\x4b\x01\x02"; $addCentralRecord .="\x00\x00"; $addCentralRecord .="\x0a\x00"; $addCentralRecord .="\x00\x00"; $addCentralRecord .="\x00\x00"; $addCentralRecord .="\x00\x00\x00\x00"; $addCentralRecord .= pack("V",0); $addCentralRecord .= pack("V",0); $addCentralRecord .= pack("V",0); $addCentralRecord .= pack("v", strlen($directoryName) ); $addCentralRecord .= pack("v", 0 ); $addCentralRecord .= pack("v", 0 ); $addCentralRecord .= pack("v", 0 ); $addCentralRecord .= pack("v", 0 ); $ext = "\x00\x00\x10\x00"; $ext = "\xff\xff\xff\xff"; $addCentralRecord .= pack("V", 16 ); $addCentralRecord .= pack("V", $this -> oldOffset ); $this -> oldOffset = $newOffset; $addCentralRecord .= $directoryName; $this -> centralDirectory[] = $addCentralRecord; } /** * Function to add file(s) to the specified directory in the archive * * @param $directoryName string * */ public function addFile($data, $directoryName) { $directoryName = str_replace("\\", "/", $directoryName); $feedArrayRow = "\x50\x4b\x03\x04"; $feedArrayRow .= "\x14\x00"; $feedArrayRow .= "\x00\x00"; $feedArrayRow .= "\x08\x00"; $feedArrayRow .= "\x00\x00\x00\x00"; $uncompressedLength = strlen($data); $compression = crc32($data); $gzCompressedData = gzcompress($data); $gzCompressedData = substr( substr($gzCompressedData, 0, strlen($gzCompressedData) - 4), 2); $compressedLength = strlen($gzCompressedData); $feedArrayRow .= pack("V",$compression); $feedArrayRow .= pack("V",$compressedLength); $feedArrayRow .= pack("V",$uncompressedLength); $feedArrayRow .= pack("v", strlen($directoryName) ); $feedArrayRow .= pack("v", 0 ); $feedArrayRow .= $directoryName; $feedArrayRow .= $gzCompressedData; $feedArrayRow .= pack("V",$compression); $feedArrayRow .= pack("V",$compressedLength); $feedArrayRow .= pack("V",$uncompressedLength); $this -> compressedData[] = $feedArrayRow; $newOffset = strlen(implode("", $this->compressedData)); $addCentralRecord = "\x50\x4b\x01\x02"; $addCentralRecord .="\x00\x00"; $addCentralRecord .="\x14\x00"; $addCentralRecord .="\x00\x00"; $addCentralRecord .="\x08\x00"; $addCentralRecord .="\x00\x00\x00\x00"; $addCentralRecord .= pack("V",$compression); $addCentralRecord .= pack("V",$compressedLength); $addCentralRecord .= pack("V",$uncompressedLength); $addCentralRecord .= pack("v", strlen($directoryName) ); $addCentralRecord .= pack("v", 0 ); $addCentralRecord .= pack("v", 0 ); $addCentralRecord .= pack("v", 0 ); $addCentralRecord .= pack("v", 0 ); $addCentralRecord .= pack("V", 32 ); $addCentralRecord .= pack("V", $this -> oldOffset ); $this -> oldOffset = $newOffset; $addCentralRecord .= $directoryName; $this -> centralDirectory[] = $addCentralRecord; } /** * Fucntion to return the zip file * * @return zipfile (archive) */ public function getZippedfile() { $data = implode("", $this -> compressedData); $controlDirectory = implode("", $this -> centralDirectory); return $data. $controlDirectory. $this -> endOfCentralDirectory. pack("v", sizeof($this -> centralDirectory)). pack("v", sizeof($this -> centralDirectory)). pack("V", strlen($controlDirectory)). pack("V", strlen($data)).
