I PHP, hvordan man viser matrixindhold i en tabel

Noget tæt på den mysql-klient udgange:

$data = array(
    array(
        'group_id'            => '1',
        'group_supergroup_id' => '4',
        'group_deletable'     => '0',
        'group_label'         => 'default',
    ),
    array(
        'group_id'            => '8',
        'group_supergroup_id' => '1',
        'group_deletable'     => '1',
        'group_label'         => 'dbdfg',
    ),
);

if ( empty($data) ) {
    echo "Empty set";
} else {
    // determine widths of titles
    $colWidths = array();
    foreach ( $data[0] as $title => $value ) {
        $colWidths[$title] = strlen($title);
    }
    // determine widths of columns
    foreach ( $data as $row ) {
        foreach ( $row as $title => $value ) {
            if ( is_null($value) ) {
                $value = 'NULL';
            }
            if ( $colWidths[$title] < strlen($value) ) {
                $colWidths[$title] = strlen($value);
            }
        }
    }
    // generate horizontal border
    $horizontalBorder = '+';
    foreach ( $colWidths as $title => $width ) {
        $horizontalBorder .= str_repeat('-', $width + 2) . "+";
    }
    $horizontalBorder .= "\n";
    // print titles
    echo $horizontalBorder;
    echo '|';
    foreach ( $data[0] as $title => $value ) {
        printf(" %-{$colWidths[$title]}s |", $title);
    }
    echo "\n";
    echo $horizontalBorder;
    // print contents
    foreach ( $data as $row ) {
        echo "|";
        foreach ( $row as $title => $value ) {
            if ( is_null($value) ) {
                $value = 'NULL';
            }
            printf(" %-{$colWidths[$title]}s |", $value);
        }
        echo "\n";
    }
    echo $horizontalBorder;
}
