    Hello,

    You need to enable the useHTMLExtended option, that is available in Premium packages.

    For example:

    $html = '<p>A math equation using MathML:</p><math xmlns="http://www.w3.org/1998/Math/MathML"><mrow><mi>A</mi><mo>=</mo></mrow></math><p>Paragraph after the math equation.</p>';

$docx->embedHTML($html, array('useHTMLExtended' => true));

    HTML Extended and CSS Extended requires enabling this option.

    Also please avoid escaping " when adding HTML contents. Instead of:

    $htmlString = '<p>A math equation using MathML:</p><math xmlns=\"http://www.w3.org/1998/Math/MathML\"><mrow><mi>A</mi><mo>=</mo></mrow></math><p>Paragraph after the math equation.</p>';

    use:

    $htmlString = '<p>A math equation using MathML:</p><math xmlns="http://www.w3.org/1998/Math/MathML"><mrow><mi>A</mi><mo>=</mo></mrow></math><p>Paragraph after the math equation.</p>';

    On https://www.phpdocx.com/documentation/introduction/html-extended-to-word-PHP you can read more information this feature.

    We also recommend you check the samples included in the package. In the Core/embedHTML folder you can find many sample scripts using HTML Extended and CSS Extended.

    Regards.
