Are there any potential pitfalls to be aware of when using the implode function in PHP to concatenate array elements?

One potential pitfall when using the implode function in PHP to concatenate array elements is that it will throw a warning if you try to implode an array that contains non-string values. To avoid this issue, you can use array_map to ensure that all elements in the array are converted to strings before imploding them. 

$array = [1, 2, 3, 4, 5];
$array = array_map('strval', $array);
$result = implode(', ', $array);
echo $result;
