Connecting 2 variables

[mr e]

ok i think it's easiest to explain with an example so here...

<?php
$opt1 = "hi";
$opt2 = "hey";
$opt3 = "hello";

$i=1;
for($i=1;$i<=3;$i++) {
print "$opt$i";
;}
?>

i want it to print "hiheyhello", but i can't figure out how or if theres a way to connect these two variables, any ideas?

You should read the PHP manual page about "Variable Variables". Until you do, this is the code you want:
<?php
$opt1 = 'hi';
$opt2 = 'hey';
$opt3 = 'hello';

for ($i = 1; $i < 4; $i++) {
echo ${'opt'.$i};
}

?>
