Split string into 2 pieces by length using PHP

Question

I have a very long string that I want to split into 2 pieces.

I ws hoping somebody could help me split the string into 2 separate strings.

I need the first s

Answer 1

There is a function called str_splitPHP Manual which might, well, just split strings:

$parts = str_split($string, $split_length = 400);

$parts is an array with each part of it being 400 (single-byte) characters at max. As per this question, you can as well assign the first and second part to individual variables (expecting the string being longer than 400 chars):

list($str_1, $str_2) = str_split(...);

Answer 2

$first400 = substr($str, 0, 400);
$theRest = substr($str, 400);

You can rename your variables to whatever suits you. Those names are just for explanation. Also if you try this on a string less than 400 characters $theRest will be FALSE

Answer 3

This is another approach if you want to break a string into n number of equal parts

<?php

$string = "This-is-a-long-string-that-has-some-random-text-with-hyphens!";
$string_length = strlen($string);

switch ($string_length) {

  case ($string_length > 0 && $string_length < 21):
    $parts = ceil($string_length / 2); // Break string into 2 parts
    $str_chunks = chunk_split($string, $parts);
    break;

  default:
    $parts = ceil($string_length / 3); // Break string into 3 parts
    $str_chunks = chunk_split($string, $parts);
    break;

}

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

?>
