PHP string Segmentation (Explode str_split preg_split_php Tutorial

Separating the strings, using "Str_split", the advantage is that even spaces are the elements of the array. My previous example is because the previous string contains 2 spaces, and the second one is only one. But the output will see the same display. You can also split by other separators, such as "explode" or "preg_split",

Preg_split--splitting a string with regular expressions
Description
Array Preg_split (string pattern, string subject [, int limit [, int flags]])

Returns an array that contains the substrings in the subject that are split along the boundary that matches the pattern.

If limit is specified, it returns up to the limit substring, and if limit is-1, it means there is no limit and can be used to continue to specify the optional parameter, flags.

Flags can be any combination of the following tags (with bitwise OR operator | Combination):
