Question

I have a string:

$str = 'Hello World, Welcome World, Bye World';

I want to cut above string into pieces. Each piece should be of 10 characters. If a word is going to be cut, then move that word to next line.

For Example:

$output = array();

$output[0] = 'Hello ';
$output[1] = 'World, ';
$output[2] = 'Welcome ';
$output[3] = 'World, Bye'; 
$output[4] = 'World';

Is there a shortest way without so many if else and loops.

Thanks

Use wordwrap. By default it wraps whole words and does not cut them into pieces.

echo wordwrap('Hello World, Welcome World, Bye World', 10);

If you want an array, explode afterwards:

print_r(explode("\n", wordwrap('Hello World, Welcome World, Bye World', 10)));
