str_split — Convert a string to an array
stringThe input string.
lengthMaximum length of the chunk.
If the optional length parameter is specified, the returned array will be broken down into chunks with each being length in length, except the final chunk which may be shorter if the string does not divide evenly. The default length is 1, meaning every chunk will be one byte in size.
If length is less than 1, a ValueError will be thrown.
| Versão | Descrição |
|---|---|
| 8.2.0 | If string is empty an empty array is now returned. Previously an array containing a single empty string was returned. |
| 8.0.0 | If length is less than 1, a ValueError will be thrown now; previously, an error of level E_WARNING has been raised instead, and the function returned false. |
Exemplo #1 Example uses of str_split()
<?php
$str = "Hello Friend";
$arr1 = str_split($str);
$arr2 = str_split($str, 3);
print_r($arr1);
print_r($arr2);
?>O exemplo acima produzirá:
Array ( [0] => H [1] => e [2] => l [3] => l [4] => o [5] => [6] => F [7] => r [8] => i [9] => e [10] => n [11] => d ) Array ( [0] => Hel [1] => lo [2] => Fri [3] => end )
Nota:
str_split() will split into bytes, rather than characters when dealing with a multi-byte encoded string. Use mb_str_split() to split the string into code points.
