How can a beginner in PHP apply a regular function to draw wave lines?

To draw wave lines in PHP, a beginner can create a regular function that generates the wave pattern using mathematical calculations. The function can then be called to output the wave lines on the screen using HTML canvas or other drawing methods. By understanding basic PHP syntax and utilizing mathematical concepts, a beginner can easily implement wave lines in their project. 

<?php
function drawWaveLines($amplitude, $frequency, $phase, $numPoints) {
    $points = array();
    
    for ($i = 0; $i < $numPoints; $i++) {
        $x = $i;
        $y = $amplitude * sin(2 * M_PI * $frequency * $x + $phase);
        $points[] = array($x, $y);
    }

    return $points;
}

$wavePoints = drawWaveLines(50, 0.1, 0, 100);

foreach ($wavePoints as $point) {
    echo '<div style="width: 1px; height: ' . $point[1] . 'px; background-color: black; display: inline-block;"></div>';
}
?>
