How to Extract the Zip file with PHP
You don’t need to require any other extra plugin for working with Zip files.
PHP has a ZipArchive class that allows us to create a zip file or extract the existing file.
ZipArchive class extractTo() method is used to extract the zip file that takes the destination absolute path as an argument.
Contents
1. On the same directory
I am assuming the Zip file is stored in the project root directory.
Create an object of the ZipArchive class and open the given zip file using $zip->open() method.
If it returns TRUE then extract the file to the specified path ($path) with extractTo() method by passing path value as an argument in it.
Here, I am extracting the file in project files directory.
Completed Code
// Get Project path define(‘_PATH’, dirname(__FILE__)); // Zip file name $filename = ‘zipfile.zip’; $zip = new ZipArchive; $res = $zip->open($filename); if ($res === TRUE) < // Unzip path $path = _PATH."/files/"; // Extract file $zip->extractTo($path); $zip->close(); echo ‘Unzip!’; > else
2. Specific file
With file element, you can select the zip file that you want to extract.
If a selected file is valid then pass $_FILES[‘file’][‘tmp_name’] to open() method and extract it to specified path using extractTo() method.
Completed Code
open($tmp_name); if ($res === TRUE) < // Unzip path $path = _PATH."/files/"; // Extract file $zip->extractTo($path); $zip->close(); echo 'Unzip!'; > else < echo 'failed!'; >>else < echo 'Invalid file'; >> ?>
3. Conclusion
Using the above PHP script you can extract the existing zip files at the specified location. For this, you need to pass the absolute path in extractTo() method of ZipArchive Class.
