Detailed Description

Bidi.

The Bidi class applies bidirectional formatting to text by wrapping the input with directional isolation control characters. It detects the primary directionality (left-to-right or right-to-left) of the text and ensures that mixed-direction content is rendered correctly.

Usage Example: echo $bidi->process( 'Hello World' );

Since: 1.45

Member Function Documentation

◆ process()

Wikimedia\Leximorph\Handler\Bidi::process ( string $value )

Applies bidirectional formatting to the provided text.

This method determines the primary text direction (LTR or RTL) by examining the first strongly directional codepoint in the string. It then wraps the text with the appropriate directional control characters: LRE and PDF for left-to-right, RLE and PDF for right-to-left. If no strong directionality is detected, the text is returned unmodified.

Parameters

string $value The text to format.

Since: 1.45

Returns: string The text with directional controls, or the original text.
