public static function Html::escape

public static Html::escape($text)

Escapes text by converting special characters to HTML entities.

This method escapes HTML for sanitization purposes by replacing the following special characters with their HTML entity equivalents:

• & (ampersand) becomes &
• " (double quote) becomes "
• ' (single quote) becomes '
• < (less than) becomes &lt;
• > (greater than) becomes &gt;

Special characters that have already been escaped will be double-escaped (for example, "&lt;" becomes "&amp;lt;"), and invalid UTF-8 encoding will be converted to the Unicode replacement character ("�").

This method is not the opposite of Html::decodeEntities(). For example, this method will not encode "é" to "&eacute;", whereas Html::decodeEntities() will convert all HTML entities to UTF-8 bytes, including "&eacute;" and "&lt;" to "é" and "<".

When constructing render arrays passing the output of Html::escape() to '#markup' is not recommended. Use the '#plain_text' key instead and the renderer will autoescape the text.

Parameters

string $text: The input text.

Return value

string The text with all HTML special characters converted.
