Functions of the ziparchive function in PHP

This article mainly introduces the function of the ziparchive function in PHP, the interested friend's reference, hope to be helpful to everybody.

First, unzip the zip file

$zip =new ziparchive;//Create a new Ziparchive object   if ($zip->open (' Test.zip ') ===true) {   $zip->extractto (' Images ');//Assume that the extract is within the current path under the Images folder   $zip->close ();//close processed zip file}

Compress the file into a zip file

$zip =new ziparchive; if ($zip->open (' Test.zip ', ziparchive::overwrite) ===true) {   $zip->addfile (' image.txt ');// Assume that the file name is Image.txt, under the current path   $zip->close ();}

Third, file append content to zip file

$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 ';}

Iv. Package a folder into a zip file

function Addfiletozip ($path, $zip) {   $handler =opendir ($path);//Open the current folder is specified by $path. While   (($filename =readdir ($handler))!==false) {     if ($filename! = "." && $filename! = "...") {//Folder file name is '. ' and '. ', do not operate on them       if (Is_dir ($path. ") /". $filename)) {//If an object being read is a folder, the recursive         addfiletozip ($path." /". $filename, $zip);       } else{//Add files 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 method, operate on the root directory to be packaged and pass the Ziparchive object to the method   $zip->close ();//Close the processed zip file}
