开发PHP应用程序时的错误处理

When I have a runtime error during PHP development instead of getting a line number (like in Java) I simply get a HTTP 500 internal server error.

In order to get an idea of what line the error is happening I have to comment out each line of code until the application runs. Is this normal practice for a PHP developer or am I missing something.

I have tried the following with no success:

error_reporting(E_ERROR | E_WARNING | E_PARSE);

I am developing locally on Mac OS 10.7 Apache Web server.

Not sure why the downvotes, but here is the solution. Thanks ceejayoz.

ini_set('display_errors', true);
