Zip_entry_filesize()

The zip_entry_filesize() function is a built-in function in PHP that is used to get the uncompressed size of a file in a zip archive. The uncompressed size is the size of the file before it was compressed using the zip compression algorithm.

Syntax

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

int zip_entry_filesize(resource $zip_entry)

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_filesize() in PHP.

Example: Getting the Uncompressed Size of a File in a Zip Archive

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

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

// get the uncompressed size of the file
$uncompressed_size = zip_entry_filesize($zip_entry);

echo "The uncompressed size of the file is: " . $uncompressed_size . " bytes.";

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 uncompressed size using zip_entry_filesize(). Finally, the uncompressed size is outputted to the user.
