How To Create ZIP files Using PHP
Previously, we posted a feature on a pretty neat script that allows you to unzip files (on a server) using PHP. This time, allow me to present you with a snippet that does the exact opposite: compress files into a zip file.
Now, there are a handful of ways you can actually do this with PHP but I thought some of you guys might want to give this one submitted by Vamsi Krishna from CatsWhoCode a try.
For this to work properly you’ll have to create a folder in which this file is going to run in and a files folder to create the files you intend to zip.
<?php $error = ""; //error holder if(isset($_POST['createpdf'])){ $post = $_POST; $file_folder = "files/"; // folder to load files if(extension_loaded('zip')){ // Checking ZIP extension is available if(isset($post['files']) and count($post['files']) > 0){ // Checking files are selected $zip = new ZipArchive(); // Load zip library $zip_name = time().".zip"; // Zip name if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE){ // Opening zip file to load files $error .= "* Sorry ZIP creation failed at this time<br/>"; } foreach($post['files'] as $file){ $zip->addFile($file_folder.$file); // Adding files into zip } $zip->close(); if(file_exists($zip_name)){ // push to download the zip header('Content-type: application/zip'); header('Content-Disposition: attachment; filename="'.$zip_name.'"'); readfile($zip_name); // remove zip file is exists in temp path unlink($zip_name); } }else $error .= "* Please select file to zip <br/>"; }else $error .= "* You dont have ZIP extension<br/>"; } ?> <!DOCTYPE html> <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Download As Zip</title> </head> <body> <center><h1>Create Zip</h1></center> <form name="zips" method="post"> <?php if(!empty($error)) { ?> <p style=" border:#C10000 1px solid; background-color:#FFA8A8; color:#B00000;padding:8px; width:588px; margin:0 auto 10px;"><?php echo $error; ?></p> <?php } ?> <table width="600" border="1" align="center" cellpadding="10" cellspacing="0" style="border-collapse:collapse; border:#ccc 1px solid;"> <tr> <td width="33" align="center">*</td> <td width="117" align="center">File Type</td> <td width="382">File Name</td> </tr> <tr> <td align="center"><input type="checkbox" name="files[]" value="flowers.jpg" /></td> <td align="center"><img src="files/image.png" title="Image" width="16" height="16" /></td> <td>flowers.jpg</td> </tr> <tr> <td align="center"><input type="checkbox" name="files[]" value="fun.jpg" /></td> <td align="center"><img src="files/image.png" title="Image" width="16" height="16" /></td> <td>fun.jpg</td> </tr> <tr> <td align="center"><input type="checkbox" name="files[]" value="uvamsi.docx" /></td> <td align="center"><img src="files/doc.png" title="Document" width="16" height="16" /></td> <td>uvamsi.docx</td> </tr> <tr> <td align="center"><input type="checkbox" name="files[]" value="abc.pdf" /></td> <td align="center"><img src="files/pdf.png" title="pdf" width="16" height="16" /></td> <td>abc.pdf</td> </tr> <tr> <td colspan="3" align="center"> <input type="submit" name="createpdf" style="border:0px; background-color:#800040; color:#FFF; padding:10px; cursor:pointer; font-weight:bold; border-radius:5px;" value="Download as ZIP" /> <input type="reset" name="reset" style="border:0px; background-color:#D3D3D3; color:#000; font-weight:bold; padding:10px; cursor:pointer; border-radius:5px;" value="Reset" /> </td> </tr> </table> </form> </body> </html>
