How to rename and save unzip file in php?

@brenda_prosacco 

You can rename and save an unzip file in PHP using the following steps:

1. Use the zip_open() function to open the ZIP file and extract its contents. For example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

$zip = zip_open('myzipfile.zip');
if ($zip) {
    while ($zip_entry = zip_read($zip)) {
        // extract each file in the ZIP archive
        $entry_name = zip_entry_name($zip_entry);
        $entry_size = zip_entry_filesize($zip_entry);
        $entry_content = zip_entry_read($zip_entry, $entry_size);
        // ...
    }
    zip_close($zip);
}

1. Use the file_put_contents() function to save the extracted file with a new name. For example:

1
2
3

$extracted_file_path = '/path/to/extracted/file';
$new_file_name = 'newfilename.txt';
file_put_contents($extracted_file_path . '/' . $new_file_name, $entry_content);

The file_put_contents() function takes two arguments: the first argument is the file path where you want to save the file, and the second argument is the contents of the file you want to save.

So, in summary, you can extract the contents of the ZIP file using zip_open(), then loop through the extracted files and use file_put_contents() to save each file with a new name.

Please note that the zip functions used in the above code are available in PHP versions before 8.0.0. In PHP 8.0.0 and later, the ext-zip extension is required to work with ZIP files.

Here is an updated version of the code using the ext-zip extension:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14

$zip = new ZipArchive;
if ($zip->open('myzipfile.zip') === TRUE) {
    for ($i = 0; $i < $zip->numFiles; $i++) {
        $entry_name = $zip->getNameIndex($i);
        $entry_content = $zip->getFromIndex($i);
        
        // Specify the new file name
        $new_file_name = 'newfilename.txt';

        // Save the extracted file with a new name
        file_put_contents($new_file_name, $entry_content);
    }
    $zip->close();
}

In this updated version, we use the ZipArchive class to open the ZIP file and extract its contents. We iterate over each file using a for loop and retrieve the file contents using the getFromIndex() method. We then use file_put_contents() to save the extracted file with a new name.

Remember to replace 'myzipfile.zip' with the path to your actual ZIP file and 'newfilename.txt' with the desired new file name.

Make sure the necessary permissions are set to read and write the files.
