The following example demonstrates how to use zip_entry_close() to properly close a zip entry after reading it ?

<?php
    $zip = zip_open("new.zip");
    
    if ($zip) {
        $zip_entry = zip_read($zip);
        
        if ($zip_entry) {
            // Open the zip entry for reading
            zip_entry_open($zip, $zip_entry, "rb");
            
            // Get the name of the entry
            $myfile = zip_entry_name($zip_entry);
            
            // Close the zip entry
            $res = zip_entry_close($zip_entry);
            
            if ($res == true) {
                echo "$myfile closed successfully!";
            } else {
                echo "$myfile cannot be closed!";
            }
        }
        
        zip_close($zip);
    }
?>

Key Points

• Always call zip_entry_close() after working with a zip entry to free up resources

• This function should be used in conjunction with zip_entry_open()

• The Zip extension functions are deprecated as of PHP 8.0.0

• For new projects, consider using the ZipArchive class instead

Conclusion

The zip_entry_close() function provides a way to properly close zip entries and free resources. While functional, modern PHP development should use the ZipArchive class for better functionality and future compatibility.
