PHP code to compress and decompress files

This article mainly introduces the code for php compression and decompression of files. It has certain reference value. Now I share it with everyone. Friends in need can refer to it

Note that the zip extension needs to be installed

/** * 压缩单个文件 * @method zip_file * @param string $filename 文件名 * @return boolean true|false */ function zip_file(string $filename){ if(!is_file($filename)){ return false; } $zip=new ZipArchive(); $zipName=basename($filename).'.zip'; //打开指定压缩包，不存在则创建，存在则覆盖 if($zip->open($zipName,ZipArchive::CREATE|ZipArchive::OVERWRITE)){ //将文件添加到压缩包中 if($zip->addFile($filename)){ $zip->close(); @unlink($filename); return true; }else{ return false; } }else{ return false; } } // var_dump(zip_file('22.txt')); // func_get_args // test1.zip /** * 多文件压缩 * @method zip_files * @param string $zipName 压缩包的名称，.zip结尾 * @param string $files 需要压缩文件名，可以是多个 * @return boolean true|false */ function zip_files(string $zipName,...$files){ //检测压缩包名称是否正确 $zipExt=strtolower(pathinfo($zipName,PATHINFO_EXTENSION)); if('zip'!==$zipExt){ return false; } $zip=new ZipArchive(); if($zip->open($zipName,ZipArchive::CREATE|ZipArchive::OVERWRITE)){ foreach($files as $file){ if(is_file($file)){ $zip->addFile($file); } } $zip->close(); return true; }else{ return false; } } // var_dump(zip_files('test1.zip','22.txt')); // var_dump(zip_files('test2.zip','doUpload.php','downLoad.html','upload.html')); /** * 解压缩 * @method unzip_file * @param string $zipName 压缩包名称 * @param string $dest 解压到指定目录 * @return boolean true|false */ function unzip_file(string $zipName,string $dest){ //检测要解压压缩包是否存在 if(!is_file($zipName)){ return false; } //检测目标路径是否存在 if(!is_dir($dest)){ mkdir($dest,0777,true); } $zip=new ZipArchive(); if($zip->open($zipName)){ $zip->extractTo($dest); $zip->close(); return true; }else{ return false; } }
