What are the best practices for using the explode() function in PHP to split a string into an array for sorting purposes?

When using the explode() function in PHP to split a string into an array for sorting purposes, it is important to consider the delimiter that will be used to split the string. This delimiter should be chosen carefully based on the structure of the input string. Additionally, it is recommended to trim any extra whitespace from the elements of the resulting array before sorting them. Finally, the array can be sorted using functions like sort() or asort() depending on the desired sorting order. 

// Example code snippet for splitting a string into an array and sorting it
$string = "apple,orange,banana,grape";
$delimiter = ",";
$array = explode($delimiter, $string);

// Trim any extra whitespace from array elements
$array = array_map('trim', $array);

// Sort the array in ascending order
sort($array);

// Display the sorted array
print_r($array);
