SPL and foreach Optimized

Hi all, during saturday i've spent some time to optimize SPL. For my testcase it is now 3% faster then the compareable while code. If OPTIMIZED_ARRAY_CONSTRUCT is defined as in current CVS then the difference is about 3.5%. Looking at the profiling results on that .5% difference i was directed to the emalloc change posted earlier. This will bring some more % (hopefully >5%). SPL uses op1->u.EA.type as an info pointer (called spl_foreach_proxy) to keep track of its current index and cache the . This can also be used for normal foreach and make the array copying there obsolete, which also allows some more "code tricks" (as already requested/ bugged on bugs.php.net). Integrating SPL in the engine would also nearly completly drop the performance loss of the hooks which is less then 0.5% atm (foreach, array not measured yet). The optimization used with OPTIMIZED_ARRAY_CONSTRUCT could also be used for normal foreach. regards marcus
