php - Split a string by number of chars without splitting a word
Get the solution ↓↓↓
Solution:
I don't think there's a single built-in function that will do it for you, but you could do something like this:
$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."
// }

Solution:
Just go through the string, and after a number (number = 5) of chars check if the next char is a space and split. If there is no space, dont split and go to the next space :-)

Solution:
I guess i understood you as well, then you can use this function:
<?php
function str_split_len($str, $len)
{
if( $len > strlen($str) )
{
return false;
}
$strlen = strlen($str);
$result = array();
$words = ($strlen / $len);
for( $x = 1; $x <= $len; $x++ )
{
$result[] = substr($str, 0, $words);
$str = substr($str, $words, $strlen);
}
return $result;
}
/* Example */
$res = str_split_len("Split me !haha!", 3);
print_r($res);
?>
