Question

While debugging, it would help if I could exit() and use a foreach to print individual elements of an array. Any ideas?

Answer 1

If you want to easily print the contents of an array or any other PHP value, use var_dump. Calling exit() is orthogonal to this, and I think it’s quite clear to write:

var_dump($arr);
exit(1);

Another technique is to log your output, which is potentially more useful if you don’t want to sift through your output HTML to look for the output of var_dump:

error_log(var_export($arr));
exit(1);
