Ron.Herhuth,Hello！
You have made a mistake.look at the declaration of substr function:
string substr(string string, int start, int [length]);
The third parameter means sub-string's length,not the position.Hence,you
should do like this:
<?php
$searchWord = "acme corporation";
$searchWord = str_replace(' ','',$searchWord);
$chars = strlen($searchWord);
echo "$searchWord<br>";
for($i=0;$i<=$chars-3;$i++)
{
echo "$i:".($i+3)." ";
echo substr(($searchWord),$i,3) . "<br>";
}
?>
