What are the potential pitfalls of not using the correct PHP function for converting arrays to strings?

Using the incorrect PHP function for converting arrays to strings can result in unexpected output or errors in your code. To avoid this issue, it's important to use the appropriate function like `implode()` to convert arrays to strings in PHP. 

// Incorrect way to convert array to string
$array = [1, 2, 3];
$string = (string)$array; // This will not give the desired output

// Correct way to convert array to string using implode()
$array = [1, 2, 3];
$string = implode(', ', $array); // Output: "1, 2, 3"
echo $string;
