Just a note when using eval and expecting return values - the eval()'ed string must do the
returning. Take the following example script:
<?php
function ReturnArray()
{
return array("foo"=>1, "bar"=>2);
}
$test = eval("ReturnArray();");
print("Got back $test (".count($test).")\n");
$test = eval("return ReturnArray();");
print("Got back $test (".count($test).")\n");
?>
You will get back:
Got back (0)
Got back Array (2)
This ran me afoul for a little bit, but is the way eval() is supposed to work (eval is evaluating a
new PHP script).
