The zip_open() function is a built-in function in PHP that is used to open a zip archive file. The function returns a zip archive resource that can be used to read and manipulate the contents of the archive.


The syntax of the zip_open() function is as follows:

resource zip_open(string $filename [, int $flags [, string &$error ]])

Where $filename is the name of the zip archive file, $flags are the flags to use when opening the archive, and $error is a variable that will be set to an error message if an error occurs.

Usage Examples

Let's take a look at a practical example of using zip_open() in PHP.

Example: Opening a Zip Archive File

Suppose you have a zip archive file "" and want to open it in PHP. You can use the zip_open() function to do this, like this:

$zip = zip_open("");
if ($zip) {
    echo "Archive opened successfully.";
} else {
    echo "Failed to open archive.";

This code opens a zip archive file "" using zip_open(). If the file is opened successfully, it outputs "Archive opened successfully." and then closes the zip archive resource using zip_close(). If the file fails to open, it outputs "Failed to open archive."


In this article, we've discussed the PHP zip_open() function and how it can be used to open a zip archive file in PHP. We've explained what the function does, its syntax, and provided an example of how it can be used in a practical scenario.
