Syntax
Typical Usage
Converts a string to an array by breaking up the string into chunks specified by the optional length parameter.
Accepted Parameters
- string (string) (Required): The string you wish to split.
- length (integer) (Optional) (Default = 1): If specified, the split string will be be the length of length.
Return Value(s)
Returns an array with each key containing a single character or a number of characters specified in the length parameter.Notes
If the length is less than 1, str_split will return false. If the length exceeds the length of string, the entire string is returned as the only element in the array.
Examples of str_split()
Example 1
<?php
$string = "Hulk Smash";
$new_array = str_split($string);
print_r($new_array);Since length is not included, the default of one character per array key. The above will output:
Array
(
[0] => H
[1] => u
[2] => l
[3] => k
[4] =>
[5] => S
[6] => m
[7] => a
[8] => s
[9] => h
)
Example 2
<?php
$string = "Hulk Smash";
$new_array = str_split($string);
print_r($new_array, 2);Adding a length value will break the string up into chunks before storing the chunks into an array. So the result will be:
Array
(
[0] => Hu
[1] => lk
[2] => S
[3] => ma
[4] => sh
)
