What are common pitfalls when using the explode function in PHP?

One common pitfall when using the explode function in PHP is not checking if the delimiter exists in the input string before calling explode. This can result in errors or unexpected behavior if the delimiter is not found. To solve this issue, always check if the delimiter exists in the input string before using explode. 

$input_string = "Hello,World";
$delimiter = ",";
if(strpos($input_string, $delimiter) !== false){
    $result = explode($delimiter, $input_string);
    print_r($result);
} else {
    echo "Delimiter not found in input string.";
}
