Match case	Select this option if you want letter case to be taken into account when suggesting matches for code completion. Choose whether you want to match case for the first letter of for all letters.
Automatically insert single suggestions for	Automatically complete your code if there's just one suggestion for basic and type-matching completion.
Sort suggestions alphabetically	Choose this option if you want to sort items in the suggestions list in the alphabetical order instead of sorting them by relevance. You can change this behavior at any time by clicking the or icons in the suggestion list.

To use an opening parentheses `(` instead of `Enter` to apply the selected item from a completion list, open the Settings dialog (`CtrlAlt0S`), go to Editor \| General \| Code Completion, and select the Insert selected suggestion by pressing space, dot, or other context-dependent keys checkbox.

Item	Description
Only type-based completion	By default, PhpStorm suggests completion for symbols regardless of their types. With this approach, in complicated cases the list shows multiple completion variants. To make completion more precise, select the checkbox. The completion list will strongly depend on the PhpStorm inference. As a result, the list may remain empty in case of poor inference.
Suggest items with optional chaining for nullable types	By default, PhpStorm suggests completion for symbols with the optional chaining operator (?). To suppress showing such suggestions, clear the checkbox.
Expand method bodies in completion for overrides	By default, when you want to override a method from the parent class or interface and select this method from the list of completion suggestions, PhpStorm automatically adds parameters, generates a `super()` call, and adds the type information, if possible. Clear the Expand method bodies in completion for overrides checkbox to suppress automatic generation of method bodies for overrides during completion.
Completion of names	Suggest variable and parameter names: By default, the checkbox is cleared. When it is selected, PhpStorm suggests names for new variables and parameters during their declaration. These suggestions are based on the names of classes, types, and interfaces that are defined in your project, in the libraries you are using, and in standard APIs. Suggest names for class fields The option is by default turned off. Add type annotations for suggested parameter names: Select this checkbox to supply each completion suggestion with information on its type. The checkbox is available only when the Suggest variable and parameter names checkbox is selected.

In the text field to the right, specify the delay (in milliseconds) after when the popup window should appear. If this checkbox is not selected, use `Ctrl0P` to show parameter info.
