Re: Timing PHP code

What about writing a PHP page that does the following: Open a file (passed as a parameter)... read it's content to a string... perform the following regexp: preg_replace( "/^(.*)$/", "\\1\necho microtime() . ':' . '\\1';\n" ); and then eval the resulting string. This will give you a microsecond timestamp on each line of your code... You can tweak it so instead of printing the timestamp, it writes it to a file, and the append some javascript code at the end of your page to open a popup window with the contents of the "timestamp log" file. You can also make it print a difference in time instead of absolute time. Of course this is a simplification... the preg_replace will have to look for single quotes on the original line and escape them. And there is a big problem with single line blocks (i.e., ifs without { and }), because the "echo..." line will be added after the if and thus replace the original line. It's not that easy to look for those special cases... but still doable... Or you can make sure all your blocks are surrounded by { and } "David Diaz i Torrico" <ddiaz@drac.com> wrote in message news:Pine.LNX.4.30.0011281337500.27743-100000@boix.drac.ct... > On Tue, 28 Nov 2000, Milan Mlynarcik wrote: > > > Ther's no any debuger at this time.
