I. decompress the zip file

$ Zip = new ZipArchive; // Create a ZipArchive object
If ($ zip-> open('test.zip ') === TRUE ){
$ Zip-> extracloud ('images'); // assume that the file is decompressed to the images folder in the current path.
$ Zip-> close (); // close the processed zip file
}

While ($ filename = readdir ($ handler ))! = False ){
If ($ filename! = "." & $ Filename! = "..") {// The folder names are '.' and '..'. do not operate on them.
If (is_dir ($ path. "/". $ filename) {// recursion
AddFileToZip ($ path. "/". $ filename, $ zip );
} Else {// add the file to the zip object
$ Zip-> addFile ($ path. "/". $ filename );
}
}
}
@ Closedir ($ path );
}
$ Zip = new ZipArchive ();
If ($ zip-> open('images.zip ', ZipArchive: OVERWRITE) === TRUE ){
AddFileToZip ('images/', $ zip); // call a method to operate the root directory to be packaged, and pass the ZipArchive object to the method
$ Zip-> close (); // close the processed zip file
}
