Use this page to configure behavior of the Debugger and customize its view.
Focus application on breakpoint
If this check box is selected, on hitting a breakpoint, PhpStorm will show the location of this breakpoint in the editor and will attempt to bring its frame to the front.
Show debug window on breakpoint
Is this check box is selected, PhpStorm activates the Debug Tool Window on hitting a breakpoint.
Hide debug window on process termination
Automatically hide the Debug window when the debugged program terminates.
Scroll execution point to center
If this check box is selected, the line with the current execution point will be kept in the middle of the screen.
Use this spin box to specify the port on which the built-in web server runs. By default this port is set to the default PhpStorm port 63342 through which PhpStorm accepts connections from services. You can set the port number to any other value starting with 1024 and higher.
Can accept external connections
If this check box is selected, then the files on the built-in server running on the specified port are accessible from another computer. If this check box is cleared (by default), then the debugger listens only to local connections.
Allow unsigned requests
For security reasons, any request to a page on the built-in server from outside PhpStorm is by default rejected and the following authorization pop-up window is displayed: To access the requested page, click Copy authorization URL to clipboard and paste the generated token in the address bar of the browser.
However this behaviour may be annoying, for example, it may block your debugging session if manual intervention is impossible. To suppress displaying the authorization pop-up window, select the Allow unsigned requests check box.
