I have a string of 5000 char and I want to split it in small chunks of 200 char, split_str() function does that but I would like the strings chopped at the last full stop in the string rather than cutting a word or sentence in half.
here is an example:
<?php
$str = '<h1>Samsung Z4. smartphone com Tizen. pode estar perto de ser lançado em novo país<h1>';
$arr = str_split($str, 20);
?>
OutPut is:
Samsung Z4. smartpho
But i need it to be smart and give me just 'Samsung Z4.'
