WP_HTML_Span{} │ WP 6.2.0

Core class used by the HTML tag processor to represent a textual span inside an HTML document.

This is a two-tuple in disguise, used to avoid the memory overhead involved in using an array for the same purpose.

This class is for internal usage of the WP_HTML_Tag_Processor class.

Internal function — this function is designed to be used by the kernel itself. It is not recommended to use this function in your code.

No Hooks.

Usage

$WP_HTML_Span = new WP_HTML_Span();
// use class methods

Methods

  1. public __construct( $start, $length )

Notes

Changelog

Since 6.2.0 Introduced.
Since 6.5.0 Replaced end with length to more closely align with substr().
