wp_specialchars_decode( string $string, string|int $quote_style = ENT_NOQUOTES )
Converts a number of HTML entities into their special characters.
Description Description
Specifically deals with: &, <, >, ", and ‘.
$quote_style can be set to ENT_COMPAT to decode " entities, or ENT_QUOTES to do both " and ‘. Default is ENT_NOQUOTES where no quotes are decoded.
Parameters Parameters
- $string
-
(string) (Required) The text which is to be decoded.
- $quote_style
-
(string|int) (Optional) Converts double quotes if set to ENT_COMPAT, both single and double if set to ENT_QUOTES or none if set to ENT_NOQUOTES. Also compatible with old _wp_specialchars() values; converting single quotes if set to 'single', double if set to 'double' or both if otherwise set. Default is ENT_NOQUOTES.
Default value: ENT_NOQUOTES
Return Return
(string) The decoded text without HTML entities.
