What is the significance of validating the resulting array after splitting a string in PHP?

When splitting a string in PHP using the `explode()` function, it is important to validate the resulting array to ensure that the string was successfully split into the desired elements. This validation helps prevent errors in the code that may occur if the string was not split correctly or if the resulting array is empty.

// Splitting a string and validating the resulting array
$string = "Hello,World,PHP";
$delimiter = ",";
$split_array = explode($delimiter, $string);

// Validate the resulting array
if(count($split_array) > 1) {
    // Array has more than one element, proceed with further processing
    // Example: print_r($split_array);
} else {
    // Array has less than two elements, handle the error or unexpected result
    echo "Error: String was not split correctly.";
}
