How can ImageMagick be utilized to merge images into a video file in PHP?

To merge images into a video file using ImageMagick in PHP, you can create a loop to iterate through each image file and use the `convert` command to append each image to the video file. You can also specify the duration of each frame using the `-delay` option.

<?php

$images = ['image1.jpg', 'image2.jpg', 'image3.jpg']; // array of image files
$outputFile = 'output.mp4'; // output video file

$delay = 100; // delay between frames (in milliseconds)

foreach ($images as $image) {
    $command = "convert $image -resize 1920x1080 -background black -gravity center -extent 1920x1080 -delay $delay -loop 0 $outputFile";
    exec($command);
}

echo 'Video file created successfully!';
?>
