A breakpoint is a flag in the source code that tells the debugger to stop execution of the program. When your program stops on a breakpoint, you can perform actions like examining the value of variables and single-stepping through your program.
Set a breakpoint for a line in your PHP code. To set a breakpoint, left-click the left margin or line number of the line. To remove the breakpoint, left-click the breakpoint icon.
The Source Editor indicates a line breakpoint by highlighting the line at which the breakpoint is set in red and placing an annotation in the left margin. The following table describes the debugging annotations.
| Annotation | Description |
|---|---|
| Breakpoint |
| Disabled breakpoint |
| Invalid breakpoint |

Program counter and one breakpoint |
| The call site or place in the source code from which the current call on the call stack was made |
| Suspended threads |
| Thread suspended by hitting a breakpoint |
You can view and organize all IDE breakpoints by choosing Windows > Debugging > Breakpoints (Alt-Shift-5).
The Breakpoints window lists all of the breakpoints defined for all of your IDE projects. If you have numerous breakpoints set in the IDE, it is useful to organize these breakpoints into groups. Once your breakpoints are placed into groups, you can enable, disable, and delete them as a single unit.
