PHP ZipArchive 是PHP自带的扩展类,可以轻松实现ZIP文件的压缩和解压,使用前首先要确保PHP ZIP 扩展已经开启,具体开启方法就不说了,不同的平台开启PHP扩增的方法网上都有,如有疑问欢迎交流。这里整理一下常用的示例供参考。
一、解压缩zip文件
$zip = new ZipArchive;//新建一个ZipArchive的对象/*通过ZipArchive的对象处理zip文件$zip->open这个方法的参数表示处理的zip文件名。如果对zip文件对象操作成功,$zip->open这个方法会返回TRUE*/if ($zip->open('test.zip') === TRUE){$zip->extractTo('images');//假设解压缩到在当前路径下images文件夹的子文件夹php$zip->close();//关闭处理的zip文件}
二、将文件压缩成zip文件
$zip = new ZipArchive;/*$zip->open这个方法第一个参数表示处理的zip文件名。第二个参数表示处理模式,ZipArchive::OVERWRITE表示如果zip文件存在,就覆盖掉原来的zip文件。如果参数使用ZIPARCHIVE::CREATE,系统就会往原来的zip文件里添加内容。如果不是为了多次添加内容到zip文件,建议使用ZipArchive::OVERWRITE。使用这两个参数,如果zip文件不存在,系统都会自动新建。如果对zip文件对象操作成功,$zip->open这个方法会返回TRUE*/if ($zip->open('test.zip', ZipArchive::OVERWRITE) === TRUE){$zip->addFile('image.txt');//假设加入的文件名是image.txt,在当前路径下$zip->close();}
三、文件追加内容添加到zip文件
$zip = new ZipArchive;$res = $zip->open('test.zip', ZipArchive::CREATE);if ($res === TRUE) {$zip->addFromString('test.txt', 'file content goes here');$zip->close();echo 'ok';} else {echo 'failed';}
四、将文件夹打包成zip文件
function addFileToZip($path, $zip) {$handler = opendir($path); //打开当前文件夹由$path指定。/*循环的读取文件夹下的所有文件和文件夹其中$filename = readdir($handler)是每次循环的时候将读取的文件名赋值给$filename,为了不陷于死循环,所以还要让$filename !== false。一定要用!==,因为如果某个文件名如果叫'0',或者某些被系统认为是代表false,用!=就会停止循环*/while (($filename = readdir($handler)) !== false) {if ($filename != "." && $filename != "..") {//文件夹文件名字为'.'和‘..’,不要对他们进行操作if (is_dir($path . "/" . $filename)) {// 如果读取的某个对象是文件夹,则递归addFileToZip($path . "/" . $filename, $zip);} else { //将文件加入zip对象$zip->addFile($path . "/" . $filename);}}}@closedir($path);}$zip = new ZipArchive();if ($zip->open('images.zip', ZipArchive::OVERWRITE) === TRUE) {addFileToZip('images/', $zip); //调用方法,对要打包的根目录进行操作,并将ZipArchive的对象传递给方法$zip->close(); //关闭处理的zip文件}
ZipArchive方法如下:
ZipArchive::addEmptyDir — Add a new directory
ZipArchive::addFile — Adds a file to a ZIP archive from the given path
ZipArchive::addFromString — Add a file to a ZIP archive using its contents
ZipArchive::close — Close the active archive (opened or newly created)
ZipArchive::deleteIndex — delete an entry in the archive using its index
ZipArchive::deleteName — delete an entry in the archive using its name
ZipArchive::extractTo — Extract the archive contents
ZipArchive::getArchiveComment — Returns the Zip archive comment
ZipArchive::getCommentIndex — Returns the comment of an entry using the entry index
ZipArchive::getCommentName — Returns the comment of an entry using the entry name
ZipArchive::getFromIndex — Returns the entry contents using its index
ZipArchive::getFromName — Returns the entry contents using its name
ZipArchive::getNameIndex — Returns the name of an entry using its index
ZipArchive::getStatusString — Returns the status error message, system and/or zip messages
ZipArchive::getStream — Get a file handler to the entry defined by its name (read only).
ZipArchive::locateName — Returns the index of the entry in the archive
ZipArchive::open — Open a ZIP file archive
ZipArchive::renameIndex — Renames an entry defined by its index
ZipArchive::renameName — Renames an entry defined by its name
ZipArchive::setArchiveComment — Set the comment of a ZIP archive
ZipArchive::setCommentIndex — Set the comment of an entry defined by its index
ZipArchive::setCommentName — Set the comment of an entry defined by its name
ZipArchive::statIndex — Get the details of an entry defined by its index.
ZipArchive::statName — Get the details of an entry defined by its name.
ZipArchive::unchangeAll — Undo6来源gaodaimacom搞#^代%!码网搞gaodaima代码 all changes done in the archive
ZipArchive::unchangeArchive — Revert all global changes done in the archive.
ZipArchive::unchangeIndex — Revert all changes done to an entry at the given index
ZipArchive::unchangeName — Revert all changes done to an entry with the given name.
