PHPStorm: Break on all PHP errors

Note: I think this will only break on errors like bad types or missing semi-colons. It won’t break on exceptions thrown by frameworks / libraries.

• Run -> View Breakpoints
• Click on the + icon
• Choose PHP Exception Breakpoints
• Type Error as the Exception name.
• Click on the + icon
• Choose PHP Exception Breakpoints
• Type RuntimeException as the Exception name.

Now, do something to throw an error (e.g., call an undefined method foobar()) and PHPStorm should break when it encounters that error.

You can view the error by opening the Debugger tab and examining the exception / error thrown.
