What are the potential consequences of receiving a "Notice: Array to string conversion" error in PHP?

The "Notice: Array to string conversion" error in PHP occurs when trying to treat an array as a string, which is not allowed. To solve this issue, you should ensure that you are not trying to concatenate an array with a string, and instead properly handle arrays using functions like implode() to convert them to strings before concatenation.

// Example code snippet to fix "Notice: Array to string conversion" error
$array = [1, 2, 3];
$string = implode(', ', $array); // Convert array to string
echo 'Array elements: ' . $string; // Concatenate string with array elements
