Is there a function in PHP4 that does the same thing as str_split?

Or, is there simply a better way of doing this?

$the_tag = "109947744176"; // a unix timestap with 2 extra characters

$arr0 = substr(chunk_split($the_tag, 10, ':'), 0, -1); // mark off the
1st 10 characters

$arr1 = explode(":",$arr0); // separate the 1st 10 characters

$arr1_time = $arr1[0]; // collect the actual unix timestamp

$convtime = date("h:i:s a - d F Y",$arr1_time); // convert to human
readable time

echo $convtime;

Thanks!
