PHP Inline Parameter Hints

Inline parameter name hints for PHP function and method calls in VS Code. Works with both .php and .blade.php files.

After indexing open and start editing a file to see the inline hints.

PHP Parameter Hints

Features

Parameter name hints for function calls, method calls, constructors, and static methods
Blade template support: <?php ?> blocks, @php/@endphp directives, and {{ }}/{!! !!} echo expressions
Handles PHP 8 named arguments (hints are hidden for named args)
Variadic parameter expansion (...$items shows as items[0]:, items[1]:, etc.)
Caching for fast performance on large files

Visit the extension page and press install.

All settings are under phpParameterHints.* in VS Code settings.

Setting	Type	Default	Description
`phpParameterHints.enabled`	`boolean`	`true`	Enable or disable parameter hints
`phpParameterHints.literalsOnly`	`boolean`	`false`	Only show hints for literal values (strings, numbers, booleans, null, arrays)
`phpParameterHints.collapseWhenEqual`	`boolean`	`true`	Hide the hint when the variable name matches the parameter name

You can edit the background and font colors to match your style, add to the settings.json:

"workbench.colorCustomizations": {
   "editorInlayHint.parameterBackground": "#fff",
   "editorInlayHint.parameterForeground": "#000"
}

PHP files

Blade files

VS Code 1.75.0 or later
A PHP language server extension (recommended: Intelephense) for best results with built-in functions and third-party libraries

The extension works without a language server, but hints will only appear for functions and methods defined in the same file.
