PHP | str_split() Function

The str_split() is an inbuilt function in PHP and is used to convert the given string into an array. This function basically splits the given string into smaller strings of length specified by the user and stores them in an array and returns the array.

Syntax:

array str_split($org_string, $splitting_length)

Parameters:
The function accepts two parameters and are described below:

  1. $org_string (mandatory): This refers to the original string that the user needs to split into an array.
  2. $splitting_length (optional): This refers to the length of each array element, we wish to split our string into. By default the function accepts the value as 1.

Return Values: The function returns an array. If the length parameter exceeds the length of the original string, then the whole string is returned as a single element. If the length parameter is less than 1, then False is returned. By default length is equal to 1.

Examples:

Input: "Hello"
Output:
Array
(
    [0] => H
    [1] => e
    [2] => l
    [3] => l
    [4] => o
)
