function webform_replace_tokens_clear in Webform 7.4

Removes tokens from string.

Call this function in cases where you need to remove unreplaced tokens but can't call webform_replace_tokens() with the option $clear = TRUE.

In some cases the function token_replace() in webform_replace_tokens() needs to be called with the option 'clear' => FALSE, to not remove input filters. For security reasons webform_replace_tokens() is called before check_markup(), where input filters get replaced. Tokens won't be replaced if there is no value provided. These tokens, that is, [current-page:query:*] needs to be removed to not show up in the output.

Note: This function was previously named webform_clear_tokens, which conflicted with the webform_clear module, being called as hook_tokens.

Parameters

string $text: The text to have its tokens removed.

Return value

mixed|string Replace tokens with actual value.
