How do you merge words

[plznty]

I want two words to be joined into one like this:

$word1 = "ABC";

$word2 = "123";

 

OUTPUT = A1B2C3

 

Thanks

i think u can use the fgetc() for this one..

Something like this should do it:

<?php
$word1 = "ABC";
$word2 = "123";

$res = '';
for ($i = 0, $l1 = strlen($word1), $l2 = strlen($word2); $i < $l2 && $i < $l1; ++$i) {
if ($i < $l1) {
	$res .= $word1[$i];
}
if ($i < $l2) {
	$res .= $word2[$i];
}
}

echo $res;

Wow thanks, can you make it so it can revert the $res back into the variables?

Yes I can. Read the string character by character. You put every second character in one variable and the others in another variable. Why don't you try it out?
