What is the purpose of using the explode function in PHP?

The explode function in PHP is used to split a string into an array based on a specified delimiter. This can be useful when you have a string that contains multiple values separated by a specific character, such as a comma or space, and you want to extract each value individually. By using the explode function, you can easily break apart the string and access each value as a separate element in an array.

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

print_r($fruits);
