What is the purpose of using the explode function in PHP and what potential errors can occur during its implementation?

The explode function in PHP is used to split a string into an array based on a specified delimiter. This can be useful for processing data that is separated by a certain character, such as commas or spaces. One potential error that can occur during its implementation is if the delimiter is not found in the string, resulting in an array with only one element (the original string). 

// Example of using explode function to split a string by commas
$string = "apple,banana,orange";
$fruits = explode(",", $string);

print_r($fruits);
