Here this code will get you what you are looking for.
<?
$searchWord = "acme corporation";
$chars = strlen($searchWord);
echo "$searchWord<br>";
for($i=0;$i<=($chars-3);$i++)
{
#$j = $i * 3;
echo $i . ":" . $j . " ";
echo substr(($searchWord),$i,3) . "<br>";
}
?>
If you want it to look like what you had suggested you would have to remove
the space from the $searchWord variable.

The way this is writtien won't work. Because the substr() functions takes 2
arguments. The first is the start position and the second is the length.
So you are increasing the length or 'j' in the example. It is not a fixed
value of 3.

Subject: [PHP-WIN] Strange Substr Behavior
I'm trying to cycle through a keyword printing out three character
groupings starting from each letter in the keyword. Here is the script I
am using:
$searchWord = "acme corporation"
$chars = strlen($searchWord);
echo "$searchWord<br>";
for($i=0;$i<=$chars;$i++)
{
$j = $i + 3;
echo $i . ":" . $j . " ";
echo substr(($searchWord),$i,$j) . "<br>";
}
This is the output:
acme corporation
0:3 acm
1:4 cme
2:5 me co
3:6 e corp
4:7 corpor
5:8 corporat
6:9 orporatio
7:10 rporation
8:11 poration
9:12 oration
10:13 ration
11:14 ation
12:15 tion
13:16 ion
14:17 on
15:18 n
16:19
This doesn't make sense to me because it is returning more than 3
characters after the first two iterations. I understand that I have to
modify the script near the end but I'm just trying to get the base concept
working first.
Here is the output I'm looking for:
acm
cme
mec
eco
cor
orp
rpo
por
ora
rat
ati
ion
Thanks,
ROn
