How do you create a .gz file using PHP?

Question

I would like to gzip compress a file on my server using PHP. Does anyone have an example that would input a file and output a compressed file?

Answer 1

This code does the trick

// Name of the file we're compressing $file = "test.txt";  // Name of the gz file we're creating $gzfile = "test.gz";  // Open the gz file (w9 is the highest compression) $fp = gzopen ($gzfile, 'w9');  // Compress the file gzwrite ($fp, file_get_contents($file));  // Close the gz file and we're done gzclose($fp);
