PhpStorm 2024.1 Help

Editor basics

The PhpStorm editor is the main part of the IDE that you use to create, read, and modify code.

The editor consists of the following areas:

Editor details
  1. The scrollbar shows errors and warnings in the current file.

  2. Breadcrumbs help you navigate inside the code in the current file.

  3. The gutter shows line numbers, annotations, and context-dependent action icons.

  4. Tabs show the names of the currently opened files.


You can use various shortcuts to switch between the editor and different tool windows, change the editor size, switch focus, or return to the original layout.

Maximize editor pane

  • In the editor, press Ctrl+Shift+F12. PhpStorm hides all windows except the active editor.

    You can maximize a split screen as well. In this case, the active screen is maximized, and other screens are moved aside.

Switch the focus from a window to the editor

  • Press Escape. PhpStorm moves the focus from any window to the active editor.

Return to the editor from the command-line terminal

  • Press Alt+F12. PhpStorm closes the terminal window.

  • If you need to keep the terminal window open when you switch back to the active editor, press Ctrl+Tab.

Jump to the last active window

  • Press F12.

Use the switcher for navigation

  1. To jump between the opened files and tool windows with the switcher, press Ctrl+Tab.

  2. Keep Ctrl pressed to leave the switcher popup open.

  3. Press Tab to move between elements. Press Backspace to remove the selected file from the list and close it in the editor.

Change the IDE appearance

You can switch between schemes, keymaps, and viewing modes.

  1. Press Ctrl+`.

  2. In the Switch menu, select the option you need and press Enter. Use the same shortcut Ctrl+` to undo your changes.

You can adjust the color scheme settings, including the High contrast color scheme for people with eyesight deficiency, in Settings | Editor | Color Scheme. To adjust the keymap settings, go to Settings | Keymap.

  • Press Alt+Home.


When you work with code in the editor, PhpStorm displays code analysis results that include errors and warnings on the scrollbar. You can check whether your code has issues and quickly navigate to them.

The top of the scrollbar has the Inspections widget that gives you a brief summary of the code problems. Click the widget to get more information on each detected problem in the Problems tool window.

Code analysis summary

For more information, refer to Instant analysis of the current file.

The stripes on the scrollbar indicate places where PhpStorm found a problem. Hover over a stripe to see a tooltip describing the problem, or click the stripe for quick navigation.

It is normal to see many stripes while you are working on a file. Many of these errors, warnings, and suggestions are eventually resolved as you complete the code. Should any errors remain when you feel your code is complete, we recommend that you explore and resolve them before compiling your project.

The different colors of stripes indicate the severity of the problems from an error marked in red to a TODO comment marked in blue, but you can change the displayed colors if you need. For more information, refer to Change inspection severity.

Sticky lines

The sticky lines (or sticky scroll) feature enhances your coding experience by maintaining the visibility of parent elements as you scroll through the file, offering immediate context to your code.

You can also click any of the sticky lines to scroll the editor to the corresponding declaration.

PhpStorm: Sticky lines in the editor

By default, the maximum number of sticky lines is set to 5.

Configure number of sticky lines

  • Press Ctrl+Alt+S to open settings and then select Editor | General | Appearance.

Editor tabs

You can close, hide, and detach editor tabs. Every time you open a file for editing, a tab with its name is added next to the active editor tab.

To configure the settings for editor tabs, use the Settings | Editor | General | Editor Tabs page. Alternatively, right-click a tab and select Configure Editor Tabs from the list of options.

Open or close tabs

Pin or unpin a tab

You can pin an active editor tab so that it stays open when the tab limit is reached or when you use the Close Other Tabs command.

  • To pin or unpin an active tab, right-click it and select Pin Tab or Unpin Tab from the context menu.

  • To assign a keyboard shortcut for the Pin Tab action, in the Settings dialog (Ctrl+Alt+S) , go to Keymap, find the Pin Active Tab action, right-click it, select Add Keyboard Shortcut, and press the key combination you want to use.

  • To keep pinned tabs on the left side, in the Settings dialog (Ctrl+Alt+S) , go to Advanced Settings, locate the Editor Tabs section, and select the Keep pinned tabs on the left option.

Detach a tab

When you detach a tab, the tab opens in a separate window, and the window becomes reserved for the detached tab.

If you try to detach another tab from the main frame, it will be opened in the window with the already detached tab. You can position the newly detached tab anywhere you like (on the left, right, bottom, or top). You can also drag different tool windows to that frame.

  • Drag the tab you need outside the main window. If you want to re-attach the tab, drag it back over the main window.

  • To detach an active tab, press Shift+F4.

  • You can also use Alt+mouse for the same action.

Switch between tabs

  • To move between tabs, press Alt+Right or Alt+Left.

  • You can also switch between recently viewed tabs or files.

    In the editor, press Ctrl+Tab and keep holding Ctrl to keep the Switcher window open. Use Tab to select the necessary tab or file.

Assign a shortcut for the opened tab

  1. In the Settings dialog (Ctrl+Alt+S) , go to Keymap.

  2. In the list of directories, click Other and select the directory for which you want to add a shortcut. The maximum number of tabs to which you can assign shortcuts is 9.

  1. In the Settings dialog (Ctrl+Alt+S) , go to Editor | General | Editor Tabs.

  2. In the Closing Policy section, adjust the settings according to your preferences and click OK.

Open files in the preview tab

The preview tab allows you to view files in a single tab one by one without opening each file in a new tab. This is helpful if you need to look through several files without exceeding the tab limit.

  1. In the Project tool window Alt+1, click and select Enable Preview Tab.

    You can also enable the preview tab in Settings | General | Editor Tabs | Opening Policy.

  2. In the Project tool window, select a file that is not already open in any other tab.

    The name of the file is written in italics to indicate preview mode. Any other file that you select will replace the previous one in the preview tab.

    Start editing the file or double-click the file's tab to exit preview mode and convert the preview tab into a regular tab.

    Note that when the preview tab is enabled, the Open Files with Single Click option is ignored. Double-click a file to open it in a regular tab.

Hide tabs if there is no more space

  1. Press Ctrl+Alt+S to open settings and then select Editor | General | Editor Tabs.

  2. Select the Hide tabs if there is no space option. Extra tabs will be placed in the drop-down list (Show Hidden Tabs) located in the upper right part of the editor.

      • Squeeze tabs: shrink tabs to fit them on the screen.

    • Multiple rows: place tabs in several rows.

    Scroll tabs
    Squeeze tabs
    Multiple rows

Change the font size in tabs

  1. In the Settings dialog (Ctrl+Alt+S) , go to Appearance & Behavior | Appearance.

  2. In the Size field, specify the font size and click OK to save the changes.

    Keep in mind that the font size will change not only for the tabs but for tool windows as well.

Split screen

PhpStorm offers various actions that you can invoke from the main or context menu, the editor, or the Project tool window to split the editor screen.

  • In the editor, right-click the desired editor tab and select how you want to split the editor window (Split Right or Split Down). PhpStorm creates a split view of the editor and places it according to your selection.

  • As an alternative, go to Window | Editor Tabs and the Split and Move Right or Split and Move Down option.

  • You can drag a tab vertically or horizontally in order to split the editor, and drag the tab back to unsplit the screen.

    Drag-and-drop tab
  • You can open a file in the editor in the split on the right.

    In the Project tool window, right-click the file and select Open in Right Split from the context menu. PhpStorm will open the file in the split on the right of the editor.

    Open in Right Split

    If there are two splits and focus is in the left split, the file will be opened in the existing right split. If the focus is in the right split, the file will be opened in the next right split.

  • You can move files between split screens. Right-click the necessary file tab in the editor and select Move To Opposite Group or Open In Opposite Group from the context menu.

  • You can close all the open tool windows at once and thus enlarge the split screens. Place the caret in an editor tab and press Ctrl+Shift+F12 or just double-click the tab. PhpStorm hides all the open tool windows, so all the space is shared by split screens.

  • You can split the editor equally multiple times with the Equalize proportions in nested splits option.

  • To unsplit the screen, from the context menu, select Unsplit or Unsplit All to unsplit all the split frames.

Move the split screen

  1. Place the caret inside the desired split frame.

  2. In the main menu, go to Window | Editor Tabs.

  3. From the list of options, select one of the following options:

    • Stretch Editor to Top

    • Stretch Editor to Left

    • Stretch Editor to Bottom

    • Stretch Editor to Right

    You can assign a shortcut to each option and use the keyboard to stretch the split frame.

    To move between the split frames, go to Window | Editor Tabs. From the list of options, select Goto Next Splitter ⌥ ⇥ or Goto Previous Splitter ⌥ ⇧ ⇥, respectively.


You can configure and change the font, its size, and font ligatures. The font size change can be applied to one editor tab only or globally.

Configure the font and font ligatures

  1. In the Settings dialog (Ctrl+Alt+S) , go to Editor | Font.

  2. Select the desired font from the list, specify its Size and Line height. You can also enable ligatures and configure typography settings.

  3. Click OK to save the changes.

Change font size from the editor

  1. In the Settings dialog (Ctrl+Alt+S) , go to Editor | General (Mouse Control section).

  2. Select the Change font size with Ctrl+Mouse Wheel in option.

  3. Return to the editor, press and hold Ctrl, and adjust the font size using the mouse wheel.

Increase or decrease font size in all tabs

  • In the editor, press Alt+Shift+. to increase the font size globally, and Alt+Shift+Comma to decrease it.

    PhpStorm displays a zoom indicator on the bottom of the editor that shows the current font size and the default one, which you can roll back.

  • The zoom indicator is enabled by default. To disable it, open the Settings dialog (Ctrl+Alt+S) , go to Advanced Settings, and clear the Show zoom indicator option in the Editor section.
