In Php, Calling an array when it's name is stored in a variable

Question

Possible duplicate:
Convert a String to Variable

for example:

$test = array("this","is","a","test");

$what_array_to_read = "$test[0]";

function to read the array $test[0]

This is very similar to this question: stackoverflow.com/questions/433302/… On a personal note, if you need to do this, IMHO you're doing something wrong. What's the use case for this? — deceze

That is only possible using eval which should be avoided.

But if you do

$what_array_to_read = "test";
$what_index_to_read = 0;

then you can access

$$what_array_to_read[$what_index_to_read]; // will echo "this"
