The zip_entry_compressionmethod() function is a built-in function in PHP that is used to get the compression method of a file in a zip archive. The compression method is the algorithm used to compress the file in the zip archive.

Where $zip_entry is the zip_entry handle for the file in the zip archive.

Usage Examples

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

Example: Getting the Compression Method of a File in a Zip Archive

Suppose you have opened a zip archive using the PHP zip functions and want to get the compression method of a file in the archive. You can use the zip_entry_compressionmethod() function to do this, like this:

$zip = zip_open("example.zip");
$zip_entry = zip_read($zip);

// get the compression method of the file
$compression_method = zip_entry_compressionmethod($zip_entry);

echo "The compression method of the file is: " . $compression_method;

This code opens a zip archive file "example.zip" using zip_open(). We then read a file in the archive using zip_read() and get its compression method using zip_entry_compressionmethod(). Finally, the compression method is outputted to the user.
