    Guys, I'm just saying you run into speed bumps re-implementing the PHP library. Sure, C++ CAN be faster and more secure, but it's NOT a guarantee. You can easily introduce bugs and exploits while re-implementing these basic functions, which PHP either doesn't suffer, or has fixed over the years.

    Yup, that's what php's function does, although rather verbosely.

    Which I mentioned. It's still time-consuming redoing these functions. I just thought I'd mention it.

    Oh, and the whole regex thing isn't a concern anymore. It's just something I thought I'd use as an example.

    What was the problem anyway?
    I'm curious because Boost::regex does support the PCRE implementation.
    The programmer’s wife tells him: “Run to the store and pick up a loaf of bread. If they have eggs, get a dozen.”
    The programmer comes home with 12 loaves of bread.

    It could
    but why would you use a saw to cut a small piece o cake ?

    Anyone who's ever had to write a serious PHP program would tell you that the cake was actually made of wood. Unfortunately, all you get is a plastic knife.

    I agree, but Python is a great middle-ground. PHP drives me crazy to no end, and yet I'll still use it when I need to get a small script up and running. I guess that's its purpose.

    On another note though I do have a question: The idea PHP could also be used to replace C++ is news to me. Could PHP build, say, a C++ compiler, or didn't you need to go back to C or C++ to produce the relevant libraries for the PHP interpreter?
    I used PHP to sit on port 25 and pretended to be an SMTP server. It passed the commands onto Postfix for the actual processing. My goal was only to sniff the MAIL FROM, RCPT TO, and Message-ID parts of the email. I couldn't get Postfix's before queue to communicate correctly in a reasonable amount of time.

    As I worked the script I ended up putting in black list checking and checking Google (the email ultimately ends up in Google Apps but we needed our own record of the email for legal purposes) to ensure the account existed before accepting the email.

    And then I put in some small fixes to make things run smoother.

    I choose to do this in PHP as it involved quite a bit of database and socket communications (at the very least I had to open a socket to the actual Postfix install). If I had to do it in C++ (all of which I have done in the past) it would have taken me a lot longer and gained us nothing.

    As for your specific example: I would rather write the compiler in PHP than C++ due to better standard libraries. I would rather use the compiler written in C++ than the one written in PHP due to the speed.
