//Extracting a zip file
$zip = new ZipArchive;
//Open a zip file, just set it to a zip file that you want to extract
//It can be a relative path or absolute path
$res = $zip->open(’sample.zip’);
if ($res === true) {
//Zip file is exist and readable
//Start extracting the zip file
//Just specify the target location
$zip->extractTo(’path/somwhere’);
$zip->close();
//Extract success
}else{
//Zip file is not readable or not exist
echo ‘Error: ‘.$res;
}
//Creating or Overwriting a zip file
$zip = new ZipArchive;
//Specify a new zip file name and the mode
//To create a new zip file use ZipArchive::CREATE
//To overwrite an existing zip file use ZIPARCHIVE::OVERWRITE
$res = $zip->open(’sample.zip’, ZipArchive::CREATE);
if ($res === true) {
//Zip file is created
//Start adding files
//To add a string value to the zip file
//The first parameter is the file name for the zipped file
//The second parameter is the string
$zip->addFromString(’file1.txt’, ’some text or content’);
//To add a file to the zip file
//The first parameter is the file name that will be zipped
//The second parameter is the file name for the zipped file
$zip->addFile(’sample.xls’, ‘filenameinzip.xls’);
$zip->close();
