note

The PHP plugin is available only in IntelliJ IDEA Ultimate.

3. From the list, choose PHP Exception Breakpoints.

   

4. In the Add Exception Breakpoint dialog that opens, specify the errors or exceptions on which you want the debugger to suspend.

   • To break on PHP error conditions, choose one of the standard types from the list, the available options are Warning, Notice, or Deprecated.
