What are some best practices for efficiently counting splits in PHP strings?

When counting splits in PHP strings, it is best to use the `explode()` function to split the string into an array based on a delimiter and then count the number of elements in the resulting array. This method is efficient and straightforward.

$string = "apple,banana,orange,grape";
$delimiter = ",";
$splitArray = explode($delimiter, $string);
$splitCount = count($splitArray);

echo $splitCount; // Output: 4
