Write and edit source code

When you work with code, PhpStorm ensures that your work is stress-free. It offers various shortcuts and features to help you add, select, copy, move, edit, fold, find occurrences, and save code.

For navigation inside the editor, refer to Editor basics.

Find action

If you do not remember a shortcut for the action you want to use, press Ctrl+Shift+A to find any action by name.

You can use the same dialog to find classes, files, or symbols. For more information, refer to Searching Everywhere.

Add a new class, file, package, or scratch file

In the editor, press Ctrl+Alt+Insert to add a class, file, or package.
If the focus is inside the Project tool window and you want to add a new element, press Alt+Insert.
To create a new Scratch file, press Ctrl+Alt+Shift+Insert.
PhpStorm creates a temporary file that you can run and debug. For more information, refer to Scratch files.

Toggle read-only attribute of a file

If a file is read-only, it is marked with the closed lock icon in the status bar, in its editor tab, or in the Project tool window. If a file is writable, it is marked with the open lock icon in the Status bar.

Open file in the editor or select it in the Project tool window.
Do one of the following:
- From the main menu, select File | File Properties | Make File Read-only or File | File Properties | Make File Writable.
- Click the lock icon in the status bar.

If a read-only status is set by a version control system, it's suggested that you use PhpStorm version control integration features. For more information, see Version control.

Select code constructs

In the editor, place the caret at the item you want to select and press Ctrl+W/ Ctrl+Shift+W to extend or shrink your selection.
For example, in a plain text file, the selection starts within the whole word then extends to the sentence, paragraph, and so on.
In a PHP file, if you start by selecting an argument in a method call, it will extend to all arguments, then to the whole method, then to the expression containing this method, then to a larger block of expressions, and so on.
If you need just to highlight your braces, place the caret immediately after the block closing brace/bracket or before the block opening brace/bracket.

Select code according to capitalization

In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | General | Smart Keys.
Select the Use "CamelHumps" words checkbox.

If you want to use double-click when selecting according to capitalization, make sure that the Honor CamelHumps words... checkbox is selected on the Editor | General page of the Settings/Preferences dialog Ctrl+Alt+S.

Configure tabs and indents

In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | Code Style.
Select a language for which you want to configure the indentation.
From the options on the right, on the Tabs and Indents, select the Use tab character for the editor to use tabs when you press Tab, indent, or reformat code. You can also configure the tab size if you need. If you don't select this option, PhpStorm will use spaces.

Copy and paste code

You can use the standard shortcuts to copy Ctrl+C and paste Ctrl+V any selected code fragment. If nothing is selected, PhpStorm automatically copies as is the whole line where the caret is located.

By default, when you paste anything in the editor, PhpStorm performs "smart" paste, for example, pasting multiple lines in comments will automatically add the appropriate markers to the lines you are pasting. If you need to paste just plain text, press Ctrl+Alt+Shift+V.

Place the caret at a line or a symbol, right-click to open the context menu, select Copy/Paste Special | Copy Reference. When you select the Copy Reference (Ctrl+Alt+Shift+C) option, PhpStorm creates a reference string that includes the line number of the selected line or symbol. You can press Ctrl+V to paste the copied reference anywhere.
PhpStorm keeps track of everything you copy to the clipboard. To paste from history, in the editor, from the context menu, select Copy/Paste Special | Paste from History (Ctrl+Shift+V). In the dialog that opens, select your entry and click Paste.
The default number of items stored in the clipboard history is 100.
When you copy and paste code to the editor, PhpStorm displays the hidden (special) characters represented by their Unicode name abbreviation.

In the PHP context, PhpStorm can also automatically remove the opening and closing <?php ?> tags when you paste PHP code snippets. To customize this behavior, in the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | General | Smart Keys page.

Lines of code

PhpStorm offers several useful shortcuts for manipulating code lines.

To add a line after the current one, press Shift+Enter. PhpStorm moves the caret to the next line.
To add a line before the current one, press Ctrl+Alt+Enter. PhpStorm moves the caret to the previous line.
To duplicate a line, press Ctrl+D.
To sort lines alphabetically in the whole file or in a code selection, from the main menu, select Edit | Sort Lines or Edit | Reverse Lines. These actions might be helpful when you work with property files, data sets, text files, log files, and so on. If you need to assign shortcuts to those actions, refer to Configure keyboard shortcuts for more information.
To delete a line, place the caret at the line you need and press Ctrl+Y.
To join lines, place the caret at the line to which you want to join the other lines and press Ctrl+Shift+J. Keep pressing the keys until all the needed elements are joined.
You can also join string literals, a field or variable declaration, and a statement. Note that PhpStorm checks the code style settings and eliminates unwanted spaces and redundant characters.
To split string literals into two parts, press Ctrl+Enter.
PhpStorm also offers a set of handy intention actions for manipulating string literals, such as splitting a string into two concatenated strings or converting it to a sprintf call. To view the available actions, position the caret inside the string literal and press Alt+Enter or click .
To comment a line of code, place the caret at the appropriate line and press Ctrl+/.
To move a line up or down, press Alt+Shift+Up or Alt+Shift+Down respectively.
To move (swap) an XML or HTML tag attribute to the left or to the right, place the caret at it, or select it and press Ctrl+Alt+Shift+Left for left or Ctrl+Alt+Shift+Right for right.

Code statements

Move statements

In the editor, place the caret at the needed statement and press Ctrl+Shift+Up to move a statement up or Ctrl+Shift+Down to move a statement down. PhpStorm moves the selected statement performing a syntax check.

Complete current statement

In the editor, press Ctrl+Shift+Enter or from the main menu select Code | Complete Current Statement. PhpStorm inserts the required trailing comma automatically in structs, slices, and other composite literals. The caret is moved to the position where you can start typing the next statement.

Unwrap or remove statement

Place the caret at the expression you want to remove or unwrap.
Press Ctrl+Shift+Delete.
PhpStorm shows a popup with all actions available in the current context. To make it easier to distinguish between statements to be extracted and statements to be removed, PhpStorm uses different background colors.
Select an action and press Enter.

Code fragments

Move and copy code fragments by dragging them in the editor.
- To move a code fragment, select it and drag the selection to the target location.
- To copy a code selection, keeping Ctrl pressed, drag it to the target location.
  The copy action might not be available in macOS since it can conflict with global OS shortcuts.
The drag functionality is enabled by default. To disable it, in the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | General and clear the Enable Drag'n'Drop functionality in editor checkbox in the Mouse section.
To toggle between the upper and lower case for the selected code fragment, press Ctrl+Shift+U.
Note that when you apply the toggle case action to the CamelCase name format, PhpStorm converts the name to the lower case.
To comment or uncomment a code fragment, select it and press Ctrl+Shift+/.
To configure settings for commenting behavior, use options in the Comment Code section, on the Code Generation tab located in the language-specific pages under Settings/Preferences | Editor | Code Style.

Code folding

Folded code fragments are shown as shaded ellipses (). If a folded code fragment contains errors, PhpStorm highlights the fragment in red.

To configure the default code folding behavior, in the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | General | Code Folding.

Expand or collapse code elements

To fold or unfold a code fragment, press Ctrl+NumPad -/ Ctrl+NumPad +. PhpStorm folds or unfolds the current code fragment, for example, a single method.
To collapse or expand all code fragments, press Ctrl+Shift+NumPad -/ Ctrl+Shift+NumPad +.
PhpStorm collapses or expands all fragments within the selection, or, if nothing is selected, all fragments in the current file, for example, all methods in a file.
To collapse or expand code recursively, press Ctrl+Alt+NumPad -/ Ctrl+Alt+NumPad +. PhpStorm collapses or expands the current fragment and all its subordinate regions within that fragment.
To fold blocks of code, press Ctrl+Shift+.. This action collapses the code fragment between the matched pair of curly braces {}, creates a custom folding region for that fragment, and makes it "foldable".
To collapse or expand doc comments in the current file, in the main menu select Code | Folding | Expand doc comments/Collapse doc comments.
To collapse or expand a custom code fragment, select it and press Ctrl+..
You can fold or unfold any manually selected regions in code.

Fold or unfold nested fragments

To expand the current fragment and all the nested fragments, press Ctrl+NumPad *, 1. You can expand the current fragment up to the specified nesting level (from 1 to 5).
To expand all the collapsed fragments in the file, press Ctrl+Shift+NumPad *, 1. You can expand the collapsed fragments up to the specified nesting level (from 1 to 5).

Use the Surround With action

You can collapse or expand code using the Surround With action.

In the editor, select a code fragment and press Ctrl+Alt+T.
From the popup menu, select <editor-fold...> Comments or region...endregion Comments.
Optionally, specify a description under which the collapsed fragment will be hidden.
To collapse or expand the created region, press Ctrl+..
To navigate to the created custom region, press Ctrl+Alt+..

Disable code folding outline

You can disable the code folding outline that appears on the gutter.

In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | General | Code Folding.
Clear the Show code folding outline checkbox.

Autosave

PhpStorm automatically saves changes that you make in your files. Saving is triggered by various events, such as compiling, running, debugging, performing version control operations, closing a file or a project, or quitting the IDE. Saving files can be also triggered by third-party plugins.
Most of the events that trigger auto-save are predefined and cannot be configured, but you can be sure that changes will not be lost and you can find all of them in local history.

Configure autosave behavior

Press Ctrl+Alt+S to open IDE settings and select Appearance and Behavior | System Settings.
Under Autosave, configure the following options:
- Save files when switching to a different application
- Save files is the IDE is idle for N seconds

If you use version control integration, names of all modified files will be marked with a dedicated color on the file tab. But you can also mark unsaved files with an asterisk (*) on the file tab.

Mark files with unsaved changes

Press Ctrl+Alt+S to open IDE settings and select Editor | General | Editor Tabs.
Select the Mark modified (*) checkbox.

Revert changes

For most recent changes, including refactorings, press Ctrl+Z or choose Edit | Undo from the menu.
For a more detailed view of past changes, use Local History.
For the most robust tracking of all changes, use a version control system.
