CodeLobster IDE comes with full-fledged support for PHP: great code assistance, smart debugger, all major PHP frameworks support. It represents the following abilities to work with PHP code:

PHP syntax highlighting

CodeLobster IDE supports PHP syntax highlighting in the Editor to make it easier to read the semantics of the structured content by displaying each type of code in different colors and fonts. This feature helps you to check code for errors, as it highlights mismatched enclosing characters with a different color.


To change the color scheme or customize the colors or styles used for the PHP syntax highlighting, follow these steps:

  1. Open the Preferences dialog box (Tools | Preferences).

  2. Go to Editor | Colors

  3. In the Show settings for: component select PHP item and customize the colors or styles using the selectors to the right of the pane.

Pair braces highlighting

The Editor highlights pairs of:

  1. enclosing square brackets

  2. braces

  3. parenthesis ( () or () )

When the caret is placed between the beginning and ending enclosing characters. Mismatched enclosing characters are highlighted with a different color that you can change in the Preferences menu:

Ctrl + Click is a shortcut for mouse users to quickly access Go To Definition. Symbols become clickable when you press Ctrl and hover over the type or member.

To quickly navigate to the definition of a symbol, press the Ctrl key and then click on it.

Intelligent PHP autocomplete

The Intellisense autocomplete feature helps write code faster. PHP autocomplete feature makes code writing faster. Pop-up completion list includes:

  1. Both standard PHP and user's constants, variables.

  2. Functions

  3. Classes names

  4. Classes variables and functions

It is invoked automatically in the relevant area of code and lists possible names and syntax for completion.


If you place caret behind the incomplete name of a function and there's only one choice for completing in the list, it won't appear, but the function name will be completed automatically. For example, place caret after "e" symbol in the following string ove

Now press Ctrl + Space, no list will appear, but the string will turn to: overload.

PHP function info

The Parameter Info popup shows the names of parameters in method and function calls. You can review a brief description of any PHP function and its parameters. CodeLobster automatically shows a popup when you place the mouse pointer on the target function name or parameter.


Parameter Info works supports only PHP, JavaScript, and TypeScript.

You can explicitly invoke the popup if it has closed, select View | Intellisense | Parameter Info or press Ctrl + Shift + Space.

Default shortcut: Ctrl + Shift + Space

  3. Choose the Intellisense | Parameter Info menu item


Tooltips also appears when entering function parameters, and it highlights parameters separated by commas.
