How to split a long string without breaking words?

Question

I'm looking for something along the line of

str_split_whole_word($longString, $x) 

Where $longString is a collection of sentences, and $x is the character length for each line. It can be fairly long, and I want to basically split it into multiple lines in the form of an array.

For example:

$longString = 'I like apple. You like oranges. We like fruit. I like meat, also.'; $lines = str_split_whole_word($longString, $x); 

Desired output:

$lines = Array(     [0] = 'I like apple. You'     [1] = 'like oranges. We'     [2] = and so on... ) 

Answer 1

The easiest solution is to use wordwrap(), and explode() on the new line, like so:

$array = explode( "\n", wordwrap( $str, $x)); 

Where $x is a number of characters to wrap the string on.
