Simple question about variables

[bytte]

I have an array called "foo" that I want to echo to the screen.

However, the array name "foo" is dynamically generated. So I can't write this in my script:

echo $foo[0];

 

I first have to do some logic do get the variable name:

//$someOtherVar contents is the string "foo"
$varName = $someOtherVar;

 

If $varname is now containing the string "foo", then how can I get the contents of the array with the name "foo"? I can't do this, can I?

echo $varName[0];

 

I hope my question is clear.

no problem, dynamic variables (aka variable variables):

<?php
  $foo = array( 1, 2, 3 );
  $varName = 'foo';
  echo ${$varName}[0];
?>

Is this a homework assignment?
