If you want some code to be evaluated inside its own scope, wrap the eval() function inside a new
function. E.g.:
function eval_wrap($str) {
return eval($str);
}
/* Demonstration */
$x = 'not changed';
$str = "\$x = 'changed';";
eval_wrap($str);
print $x;
The evaluated code will not modify $x, because it is run inside a separate scope.
