[Resolved] split a string every 60 chars

[aaron_karp]

I need to insert a line break "\n" every 60 characters in my string, for email purposes. But the str_split function isn't available until PHP 5, and I want to make my program very portable. I also don't want to use PEAR.

Does anyone have any suggestions of how to do this? Thanks.

Consider:

$str = "012340123401234";
$len = strlen($str);
$offset = 6;
$add = "a";
$add_len = strlen($add);
for ($i = $offset; $i < $len; $i += $offset + $add_len) {
	$str = substr_replace($str, $add, $i, 0);
}
echo $str;

chunk_split can also do this, I think

yep you are right, chunk split will do it nicely.

$split_string = chunk_split($str, 60, "\n");

Good point, I missed it when looking at the links provided in split().
