Eval() Doesn't work either, or at least I can't make it work.

1. This is an example if statement that works:

if ($data[$var0] == $some_array[0] AND $data[$var1] == $some_array[1])

2. This doesn't work, I'd like to generate it through a variable:

$testString = "if (\$data[\$var0] == \$some_array[0] AND \$data[\$var1] ==

eval ($testString);

Apparently eval() only works on one line statemets such as
$testString = (\$string = \"string\";); but I don't know.

There should be a way to generate an if statemente based on some variables,
  shouldn't it?
