Question

I want to explode a string by (for example) 50 symbols (min), but without dividing words in 2 parts.

Is this possible?

Using str_split() will cause the last word to get split, which is what I don’t want.

Example: splitting string by 5 symbols;

$input = 'This is example, example can be anything.';

$output[0] = 'This';
$output[1] = 'is example,';
$output[2] = 'example';
$output[3] = 'can';
$output[4] = 'be anything';

I don’t think there’s a single built-in function that will do it for you, but you could do something like this:

Codepad Example Here

$string = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque nec elit dui, nec fermentum velit. Nullam congue ipsum ac quam auctor nec massa nunc.";

$output = array();
while (strlen($string) > 50) {
    $index = strpos($string, ' ', 50);
    $output[] = trim(substr($string, 0, $index));
    $string = substr($string, $index);
}
$output[] = trim($string);

var_dump($output);

// array(3) {
//   [0]=>
//   string(50) "Lorem ipsum dolor sit amet, consectetur adipiscing"
//   [1]=>
//   string(55) "elit. Quisque nec elit dui, nec fermentum velit. Nullam"
//   [2]=>
//   string(43) "congue ipsum ac quam auctor nec massa nunc."
// }
