If you want to create a graphical output of the  configured/embedded fonts



function outputFont( $fontName = 'Courier' ) {

    $image = new Imagick();

    $draw = new ImagickDraw();



    $draw->setGravity( Imagick::GRAVITY_CENTER );

    $draw->setFont( $fontName );

    $draw->setFontSize( 12 );

    $draw->setFillColor( 'black' );



    $image->newImage( 300, 20, new ImagickPixel( 'lightblue' ) );

    $image->annotateImage( $draw, 0, 0, 0, $fontName );

    $image->setImageFormat( 'png' );



    $src = 'data: ' . mime_content_type( $image ) . ';base64,' . base64_encode( $image );

    return '<img src="' . $src . '"> ' . $fontName . '<br>';

}



echo '<style>img{vertical-align: middle; margin-bottom: 1px;}</style>';

$fontList = \Imagick::queryFonts( '*' );

foreach ( $fontList as $fontName ) {

    echo outputFont( $fontName );

}
