How use php to manipulate files inside zip files?

Question

If I have some text files inside zip files, is it possible to manipulate this text files and change information inside this zip file?

For example, if I have the file test.txt inside test.zip, is it possible to open this text file and change the content and put other, the same as if I use fopen, fputs and fclose but all inside the zip?

Yes, you can! :)

Like this:

$zip = new ZipArchive();
$zip->open('test.zip');

// Read from file
$contents = $zip->getFromName('test.txt');
var_dump($contents);

// Write to file
$zip->addFromString('test.txt', 'foo bar');

// Close (and re-pack) zip file. Don't miss that!
$zip->close();

Check the documentation of the ZipArchive class.
