wptexturize_primes( string $haystack, string $needle, string $prime, string $open_quote, string $close_quote )
Implements a logic tree to determine whether or not “7′.” represents seven feet, then converts the special char into either a prime char or a closing quote char.
Description Description
Parameters Parameters
- $haystack
-
(string) (Required) The plain text to be searched.
- $needle
-
(string) (Required) The character to search for such as ' or ".
- $prime
-
(string) (Required) The prime char to use for replacement.
- $open_quote
-
(string) (Required) The opening quote char. Opening quote replacement must be accomplished already.
- $close_quote
-
(string) (Required) The closing quote char to use for replacement.
Return Return
(string) The $haystack value after primes and quotes replacements.
