Kept this private because I don't know in general if this is thread safe. As I understand it, the take_exception function should be safe.

As I understand the php source code, we're responsible for freeing it if we take it.

By the way, what's the benefit of having ordering on an error enum?

Example in use: #[php_function]
pub fn example_eval() -> Result<Vec<String>> {
ext_php_rs::php::eval::eval("['a', 'b', 'c']").unwrap().extract()
} |

Also I suspect this might be a bug, but it seems like wrapped functions are unable to directly return zvals? |

Add a wrapper around eval. This function exposes zend's behaviour (expects an expression which is automatically prepended with "return"), which is different PHP's builtin's behaviour.
I'm not sure if it would make sense to make a PHP equivalent
evalas well (should be really easy to make), so I don't know if we want to be conservative with the exported name.The eval portion works nicely, but I have no idea how to go from
ZendObjecttoPHPException. Currently working around this by shoving theZendObjectintoError, but this feels icky.
