Class Details

[line 95]
Text highlighter base class

This class implements all functions necessary for highlighting, but it does not contain highlighting rules. Actual highlighting is done using a descendent of this class.

One is not supposed to manually create descendent classes. Instead, describe highlighting rules in XML format and use Text_Highlighter_Generator to create descendent class. Alternatively, an instance of a descendent class can be created directly.

Use Text_Highlighter::factory() to create an object for particular language highlighter

Usage example

require_once 'Text/Highlighter.php';

$hlSQL =& Text_Highlighter::factory('SQL',array('numbers'=>true));
echo $hlSQL->highlight('SELECT * FROM table a WHERE id = 12');
