zip_entry_name(): Returns the name of a ZIP entry (file or directory).
zip_entry_filesize(): Returns the size of a ZIP entry in bytes.
zip_entry_compressedsize(): Returns the compressed size of a ZIP entry in bytes.
zip_entry_get_name(): Returns the name of a ZIP entry.

Extracting a Zip File in PHP 💡

Let's start with a practical example. In this section, we'll write a PHP script that extracts a zip file.

php

// Open the zip file
$zip = zip_open('example.zip');

// Loop through each entry in the zip file
while ($zip_entry = zip_read($zip)) {
    // Get the name, size, and type of the current entry
    $name = zip_entry_name($zip_entry);
    $size = zip_entry_filesize($zip_entry);
    $type = zip_entry_type($zip_entry);

    // If the entry is a file, extract it
    if (ZIP_FILE === $type) {
        // Create the destination directory if it doesn't exist
        $dir = dirname($name);
        if (!file_exists($dir)) {
            mkdir($dir, 0755, true);
        }

        // Open the destination file
        $fp = fopen($name, 'w');

        // Read and write the data from the zip entry to the destination file
        while ($data = zip_entry_read($zip_entry, ZIP_MEMORY, $maxlen)) {
            fwrite($fp, $data);
        }

        // Close the destination file
        fclose($fp);
    }
}

// Close the zip file
zip_close($zip);

📝 Note: The ZIP_FILE constant is used to check if the current entry is a file.

Extracting a Zip File to a Specific Directory 💡

To extract a zip file to a specific directory, simply modify the destination file path in the script above.
