Now my mail function is working fine and sending the mail. But one problem is occur, in From : address my email is sending not that one which is i mentioned in mail(). Even i had done the setting in ssmtp.cnf file.

Can u please help me to solve this issue.

Thanks once again and waiting ur reply.

I think people should know that Google has very low limits about the number of emails you can send via your GMail account – on general, you won’t be able to send more than 500 emails a day. So while this is perfect option for low volume mailing, if you have a large number of registered users and want to send a newsletter to them, this won’t work.

In this case though I was working with someone else’s code and needed the mail() function.

Thanks for the comment.

In fairness the intention was to see how quick an include_once()/require_once() is compared to an include()/require() statement when the statement is including the same file more than once – perhaps I should have been more clear about that at the outset. I wouldn’t assume that a single include_once()/require_once() statement is quicker than a single include()/require() statement.

But fair enough – I’ve taken the bait and tweaked the tests – results are above. This time each file was only included/required twice and Apache Bench was used to invoke the actual scripts.

@Greg:

Why does this matter? Well, I’d rather know than guess and the debate has been around for years. My conclusions are of course subjective, and (fancy charts notwithstanding) the empirical evidence is that include_once() and require_once() are the quickest – not the slowest.

My conclusions (the use of relative paths and that require_once()/include_once)() are quicker) are my own and I would hardly call them recommendations.

@Everyone:

What about some code to contradict/confirm these findings?

Why does this even matter? You make some assertions with fancy charts, and then proceed to recommend that people actually try what is empirically the slowest options. Please re-run the benchmarks using proper benchmarking methodology and you will see the drastic errors in your ways.

For a start, perhaps you could steal Paul M. Jones’s script for benchmarking different frameworks:

I agree – the test set up is totally artificial. However I wanted to look at the PHP functions themselves rather than start benchmarking the Apache server. The tests on http://markmail.org/message/hxzqcgrzrh6szce4 would be interesting to revisit today.

@Jaik:

I wouldn’t be too bothered with the performance differences myself – as Greg points out including the same trivial file 10,000 times hardly demonstrates anything tangible. I prefer to code in such a way that a file only ever needs to be included once anyway (by encapsulating in a class or a function).

@Sjan:

I didn’t look at __autoload() for the simple reason that I avoid using it. I did use it earlier in the Tina framework, but I found that I ended up colliding with another plugin author’s __autoload() function. In an environment where everyone is playing nicely with each other I would like to use __autoload(), but in Wordpress that doesn’t happen!
