filterLambda() and eachLambda() call create_function(), which was removed in PHP 8.0, so on PHP 8+ they die with an Error that doesn't name a replacement:

qp($xml, 'a')->filterLambda('return true;');
// Before: Error: Call to undefined function QueryPath\Helpers\create_function()
// After:  QueryPath\Exception: filterLambda() requires create_function(), which was removed in PHP 8.0. Use filterCallback() with a closure instead.

Changes

• Both methods check function_exists('create_function') before doing anything and, when it's missing, throw a QueryPath\Exception that names the replacement (filterCallback() / each()). Nothing changes on PHP 7.1–7.4.
• The @deprecated docblocks now say that the methods only work on PHP 7 and will be removed in 5.0.
• CHANGELOG entry.

Tests

DOMQueryTest::testFilterLambda and testEachLambda are no longer skipped unconditionally. Where create_function() exists they assert the old results; where it doesn't, they expect the new exception and message. Both fail on PHP 8.5 without the fix (an Error is thrown instead). The PHP 7.4 path was checked by hand, because the local vendor/ is built for PHP 8; CI covers 7.1–7.4.

Behaviour change: on PHP 8+ the thrown type goes from Error to QueryPath\Exception, so these calls can now be caught with catch (QueryPath\Exception $e).

Fixes #81.
