What are common issues when embedding multiple webcams using PHP?

One common issue when embedding multiple webcams using PHP is ensuring that each webcam is assigned a unique identifier to differentiate between them. This can be achieved by using the webcam's device ID or by dynamically generating unique IDs for each webcam. Additionally, it is important to properly handle errors and exceptions that may arise when accessing multiple webcams simultaneously.

// Example code snippet to assign unique IDs to multiple webcams
$webcam1_id = "webcam1";
$webcam2_id = "webcam2";

// Embedding webcam 1
echo "<video id='$webcam1_id' autoplay></video>";

// Embedding webcam 2
echo "<video id='$webcam2_id' autoplay></video>";
