Describing PHP explode

The explode() function is supported on PHP 4, PHP 5, PHP 7, and PHP 8. It splits a string into an array using a specified delimiter. The function returns an array of strings, where each element is a substring created by splitting the original string at the delimiter boundaries. It also accepts an optional third limit parameter to restrict the number of returned array elements.
