How can PHP beginners avoid errors like the one mentioned in the forum thread?

Issue: The error mentioned in the forum thread is likely caused by trying to access an array element that does not exist, resulting in a "Notice: Undefined offset" error. To avoid this error, beginners should always check if the array element exists before trying to access it. Solution: To avoid this error, beginners can use the isset() function to check if the array element exists before accessing it. 

// Example code snippet
$array = [1, 2, 3];

if (isset($array[2])) {
    echo $array[2]; // Output: 3
} else {
    echo "Element does not exist";
}
