Connecting 2 variables

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

PHP Code:


		
			
<?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 Code:


		
			
<?php

$opt1 = 'hi';

$opt2 = 'hey';

$opt3 = 'hello';



for ($i = 1; $i < 4; $i++) {

    echo ${'opt'.$i};

}



?>
