Smart Keys settings: PHP

Enable smart function parameters completion

When this checkbox is selected, you can use the “automatic” live template that provides completion lists for the parameters passed into functions, methods, or class constructors.

To invoke the magic live template, type the params keyword as the first parameter in the call of the function, method, or class:

IntelliJ IDEA displays a live template where the parameters are automatically completed with the variable names defined in the function declaration. To move to the next parameter, press Enter or Tab. To move to the previous parameter, press Shift+Tab.

The completion list contains variables from a local scope in the next order: with the same type, with a similar name, defined nearby. You can always switch to the usual completion mode by pressing Ctrl+Space or just typing anything which is not in the list. Variables with similar names are inserted automatically.

Select variable name without '$' sign on double click

When this checkbox is selected, only the variable name that follows the $ sign is selected on double-click or pressing Ctrl+W. This is helpful if you often need to copy variable names without $: just double-click and copy the selection.

If you still need a variable name with $ selected, place the caret before the $ sign and double-click it or press Ctrl+W.

Remove PHP open/close tags while pasting in PHP context

If selected, IntelliJ IDEA automatically removes the opening and closing <?php ?> tags from the pasted Java code snippets.

Escape symbols on paste in string literals

If selected, IntelliJ IDEA automatically inserts backslash escape symbols (\) when you paste text into a PHP string literal. For example, 'copied text' becomes \'copied text\'.

Clear the checkbox to suppress automatic symbols escaping.

Replace unnecessary double quotes on paste

If selected, IntelliJ IDEA automatically replaces unnecessary double quotes with single quotes in pasted string literals. Such cases include the literals that do not contain string interpolation, escape sequences, or single quotes. For example, echo "message" becomes echo 'message', while echo "Error: $message" remains intact.

Auto-insert '<?php' tag after typing '<?'

If selected, IntelliJ IDEA automatically inserts the <?php opening tag when you type the <? short tag. Note that short tags are deprecated in PHP 7.4, and are planned for removal in PHP 8.0. For more information, refer to RFC.

Auto-insert semicolon when it is typed inside a function call

If selected, IntelliJ IDEA automatically moves the semicolon symbol ; to the end of a function/method call when you type it after the last parameter inside the call. For example, foo($a, $b;) becomes foo($a, $b);

Show additional options when searching for method usages

If selected, when you search for usages of a method, IntelliJ IDEA will prompt you to choose whether you want to find usages of a base method or method's implementations.

Auto-insert closing HTML tag in PHPDoc blocks

If selected, IntelliJ IDEA automatically adds closing HTML tags in PHPDoc comments as you type.
