PHP compresses files into zip files

PHP ziparchive is a PHP extension class, you can easily achieve the zip file compression and decompression, before using the first to ensure that the PHP ZIP extension is open. /* Description: A function that compresses multiple files into a single zip file * @param $files Array type * @param the path to the destination target file * @param $overwrite whether to overwrite the same file as the target file */ function Create_zip ($files = Array (), $destination = ", $overwrite = False) { Returns False if the zip file already exists and is set to No Override if (file_exists ($destination) &&! $overwrite) {return false;} $valid _files = Array (); Get to a real valid file name if (Is_array ($files)) { foreach ($files as $file) { if (file_exists ($file)) { $valid _files[] = $file; } } } If there is a real valid file if (count ($valid _files)) { $zip = new Ziparchive (); Open file Overwrite if file already exists, if not, create if ($zip->open ($destination, $overwrite? Ziparchive::overwrite:ziparchive::create)!== true) {return false;} To add a file to a compressed file foreach ($valid _files as $file) { $zip->addfile ($file, $file); } Close File $zip->close (); Detects if a file exists return file_exists ($destination); }else{ return false; } } $files = Array (' tg.php '); Create_zip ($files, ' Tg.zip ', true); ?> Copy Code
