Need help on variables and cycles

[NoobNewbie]

Hi!

 

I'm new to php, and I was wondering how can we call variables thorugh a for cycle, for example. Allow me to explain:

$var1 = 'Hello';
$var2 = 'Hello again';

for($a=1;$a<=2;++$a){
    echo $var.$a;
}

 

I thought that it would echo the two variables, but it's echoing 12 instead. I believe its some syntax error, because in other languages we can do that. So, how can we do that?

I think what you're after is:

 

<?php
$var1 = 'Hello';
$var2 = 'Hello again';

for($a=1;$a<=2;++$a){
$var = 'var'.$a;
echo $$var;
}
?>
