PHP script throwing internal server error 500, fixed when turning on display_errors

I came across an issue today, that my PHP script would send a server error 500 upon finishing (on apache). The code was something like: 

//many stuff here that work
echo "It reached here";
exit;

and I was always reaching the point before the exit; command. Doing a google search, I came across this post, which suggested turning on display_errors. I did it and the 500 error went away.

So I wanted to ask, does anyone have an explanation on why this happens? This SO post describes a similar case, but there are no explanations.

As always, thanks in advance

It appears that the code generated a parse error inside an eval() function in a loop. This kind of error does not break code execution but does produce a 500 error

It's pretty likely you get a 500 status code as well, but because PHP echoes something to the browser apache won't jump in and display it's standard status 500 error page.

You would need to verify the actual status code to verify that you won't still get a 500 error.

In case of a fatal error, PHP normally sends a 500 status code. As often the process has failed at that time (hence causing the fatal) and sometime no output is generated since then, the webserver jumps in and gives the user the standard 500-internal-server-error-page.
