simple variable question

[bookbuyer2000]

How can I append a variable to a variable to make a new variable? To clarify, here is a simple example to try to get php to print the word, "dog."

<?php
$phrase1 = 'cat';
$phrase2 = 'dog';
$append = '2';

##but the following does not work:
echo "$phrase.$append";

##and neither does this:
echo "$$phrase.$append";

?>

If the above doesn't make sense, I can clarify more 🙂

Combining string pieces to form one string is commonly referred to as concatenation. For more information on concatenation, see this manual page: [man]language.operators.string[/man].

$phrase1 = 'cat';
$phrase2 = 'dog';
$append = '2';
echo ${'phrase'.$append};

However, I'd strongly recommend using an array, instead, as it's more efficient and easier to maintain:

$phrase[1] = 'cat';
$phrase[2] = 'dog';
$append = '2';
echo $phrase[$append];

AWESOME! That is so cool (how on earth did you know to do that?). Thank you!
