getDefaultValueText

Note

This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information.

This is an HHVM only function that gets the raw text associated with a default parameter

public function getDefaultValueText();

For example, for: function foo($x = FOO*FOO)

"FOO*FOO" is returned.

getDefaultValue() will return the result of FOO*FOO.

Returns​

  • string - The raw text of a default value, or empty if it does not exist.
