Split text into equal-sized variables

Question

How could I divide the value of a variable by 4. Dividing according to the number of characters.

$text = "It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout.";

In the example above I would divide by 4, and it would be 31 characters for each variable. Is there any way I can reproduce this type of result automatically regardless of the content of the $text variable?

Answer 1

Another solution is to:

$string = "It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout.";
$string_length = strlen($string);
$chunks = 4; // change to desired.
$parts = ceil($string_length / $chunks); // Break string into the 4 parts.
$str_chunks = chunk_split($string, $parts);

$string_array = array_filter(explode(PHP_EOL, $str_chunks));
print_r($string_array);

Output:

Array
(
    [0] => It is a long established fact t
    [1] => hat a reader will be distracted
    [2] =>  by the readable content of a p
    [3] => age when looking at its layout.
