CHAPTER 15 – Testing the Extension

You are now ready to write a test script to check that the extension works. Here's a sample script that opens a file test.txt, prints its contents to the standard output, and creates a copy of the file as test.txt.new: <?php $fp_in = file_open("test.txt", "r") or die("Unable to open input filen"); $fp_out = file_open("test.txt.new", "w") or die("Unable to open output filen"); while (!file_eof($fp_in)) { $str = file_read($fp_in, 1024); print($str); file_write($fp_out, $str); } file_close($fp_in); file_close($fp_out); ?>
