How to tell how many lines of code PHP read?

[acidbox]

I would like to know if there is a way to output the number of lines of code that php interpreted while compiling a page for output.

Is this possible?

Well you've got the magic constant LINE which tells you what line you're on.

Not the most efficient way of doing things, but should suffice if you are doing some debugging/profiling and not worried about performance:

// in PHP5 this also includes the original file
$files = get_included_files();
if (version_compare(phpversion(), '5.0.0') == -1) {
   // PHP4 does not include the original file (so add it!!)
   $files[] = $_SERVER['SCRIPT_FILENAME'];
}

$lines_of_code = 0;
foreach ($files as $file) {
   // should be safe to assume that the files exist and
   // are readable since they have been included!!
   $lines_of_code += count(file($file));
}

echo 'Total lines of code = '.$lines_of_code."<br />\n";

Maybe you should strip all non-php blocks (everything not between <?php and ?>) before counting

Thanks for the post bloodwine, that is a great script.
