Like I said I haven't been following this thread so have no idea what the original question was. I was just pointing out that your assertion that $compile_time == $run_time is incorrect. As far as error checking goes the PHP engine performs syntactical checks during compile time but due to the highly flexible nature of the language it's not possible to do most error checking until runtime. -Stuart -- http://stut.net/
