php – Creating .zip file

Posted by: admin April 23, 2020 Leave a comment

Questions:

I am trying to save files from one folder to another. zip folder placed in different directory. And I have written the following codes:

archive.php

<?php
    $zip = new ZipArchive();
    $zip->open('example.zip',  ZipArchive::CREATE);
    $srcDir = "/home/sam/uploads/";
    $files= scandir($srcDir);
    //var_dump($files);
    unset($files[0],$files[1]);
    foreach ($files as $file) {
        $zip->addFile("{$file}");    
    }
    $zip->close();
?>

But sadly I am not able to create the .zip folder. Is there any step I missed?

How to&Answers:
$zip = new ZipArchive();

$DelFilePath="first.zip";

if(file_exists($_SERVER['DOCUMENT_ROOT']."/TEST/".$DelFilePath)) {

        unlink ($_SERVER['DOCUMENT_ROOT']."/TEST/".$DelFilePath); 

}
if ($zip->open($_SERVER['DOCUMENT_ROOT']."/TEST/".$DelFilePath, ZIPARCHIVE::CREATE) != TRUE) {
        die ("Could not open archive");
}
    $zip->addFile("file_path","file_name");

// close and save archive

$zip->close(); 

Here TEST is your project folder name.

You can define path as you want.

Answer:

Yes I have solved my problem .

Here I have just replaced the code

$zip->addFile("{$file}");

with the code

$zip->addFromString(basename($file),  file_get_contents($file));

and get my work done. 🙂

Answer:

Try this code:

<?php
    $zip = new ZipArchive;
    if ($zip->open(getcwd() . '/test.zip', ZipArchive::CREATE) === TRUE) {
        $zip->addFile(getcwd() . '/file.txt', 'newname.txt');
        $zip->close();
        echo 'ok';
    } else {
        echo 'failed';
    }
    ?>

Answer:

Please see this below example:

<?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/>";
    }
