I have a problem; I am generating php files on the fly and storing them on the server; in case the server is out of disk space or for some other bazaar reason the generated files may get corrupted. So when loading next time will result in a parse error. In this case I simply want to be able to catch the parse error and delete the file so that it can be re-generated next time. I tried exec('php -l my_file.php'); but this takes over 5 seconds to run.

Loading 10's of include files with 1000s of lines of code to generate a page is a lot faster then checking whether a single file has parse errors. There must be a better way?

Reproduce code:
$time_start = microtime(true);
exec('php -l c:/web/temp/my_file_with_parse_errors.php');
$time_end = microtime(true);
$time = $time_end - $time_start;
echo "took $time seconds to check for parse errors :(\n";

Expected result:
took 0.0001 seconds to check for parse errors :(

Actual result:
took 5.345 seconds to check for parse errors :(
