What is difference between explode() or split() in PHP?

The explode() and split() functions are used in PHP to split the strings. Both are defined here:

Split() is used to split a string into an array using a regular expression whereas explode() is used to split the string by string using the delimiter.

Example of split():

split(":", "this:is:a:split"); //returns an array that contains this, is, a, split.

Output: Array ([0] => this,[1] => is,[2] => a,[3] => split)

Example of explode():

explode ("take", "take a explode example "); //returns an array which have value "a explode example"

Output: array([0] => "a explode example")
