Are there any potential pitfalls to be aware of when using the explode function in PHP to split a string based on a delimiter?

One potential pitfall when using the explode function in PHP is that if the delimiter is not found in the string, the function will return an array with the original string as the only element. To solve this issue, you can check if the result of explode is an array with more than one element before accessing the split values. 

$string = "apple,banana,orange";
$delimiter = ",";
$split_values = explode($delimiter, $string);

if(count($split_values) > 1){
    // Access the split values
    foreach($split_values as $value){
        echo $value . "<br>";
    }
} else {
    echo "Delimiter not found in the string.";
}
