[PHP] Is it safe to enable unused extensions?
Hi, I might need to enable several extension - out of which only a single one is used. Do these extra extensions that are enabled but not used eat up appreciable amounts of memory or in any way slow down PHP?

[PHP] SESSION variable and register_globals
Hello guys,
I have a few questions regarding the subject and was hoping you could help me
out.
1.If register_globals is on, then doing an unset($_SESSION["blah"]), to unset
a session variable will not work as the variable will be unset in that
particular instance but will be restored in next instance of that session.
Hence session_unregister("blah") also must be used to properly unset the
session with global_register on. Is this true ?
2.Furthermore, can the session be registered via the direct
assignment of $_SESSION["aaa"] = $someValue if register globals is on?
Thank you for your time.
Mohan

Re: [PHP] mail() usage in for loops
Michael Geier wrote: See answer above. With Qmail and homegrown software, I have several servers sending upwards of 13K emails per minute. All of these are HTML emails with: Custom headers, Custom unsubscribes. I create my email list and break it into files of 500, then loop through those files. I use the phpmailer class to do the sending via the qmail-inject application (allows injecting directly into the mail server, as opposed to putting into a queue). Dear Michael, When you say batches of 500 , would that mean you put pauses between each batch ? Or do you prepare each email as a file and then send them out in batches of 500? Whats the time space between each batch? Assuming I was stuck with sendmail, what would you recommend ? Thank you for your time sir.

[PHP] mail() usage in for loops
Dear all, I have read that using mail() in a for loop to send a lot of emails ( around 1k-10k ) emails is not advised due to the fact that it can be resource intensive hence or the script might take so much time that it ti,es out. However what if i append all the emails into the Bcc: header as follows and make only 1 call to mail. 1. Is this better? 2.Will it still be resource hungry? 3.What would be the best way to handle mailing to many email addresses from PHP. This is for a newsletter (not SPAM) application I am working on. 4.How does this compare against using sockets to directly speak to the SMTP server from a efficiency aspect? The code I am planning on using (which I got online too ) is as follows : $email = "[EMAIL PROTECTED]"; $subject = "test"; $body = "This is a test."; $headers = "From: [EMAIL PROTECTED]"; $headers .= "Reply-to: [EMAIL PROTECTED]"; //the following willl have all the email addresses which will receive the email $headers .= "Bcc: [EMAIL PROTECTED]"; $headers .= "Bcc: [EMAIL PROTECTED]"; $headers .= "Bcc: [EMAIL PROTECTED]"; $headers .= "Bcc: [EMAIL PROTECTED]"; $headers .= "Bcc: [EMAIL PROTECTED]"; //..and so on... $headers .= "Content-Type: text/plain; charset=iso-8859-1\n"; mail ($email, $subject, $body, $headers); -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

And use cron jobs to send the emails out every hour -- would that be ok? What would you consider excessive, say we limit each email list to about 1k subscribers, do you think your average hosting company will have a problem with that ? 3. there are many excellent PHP mail classes (PHPClasses has a few and PHPMailer is an excellent alternative as well) Thanks a lot. Looking at them now. 4. IM(H)O, if you are going to send out large amounts of mail, dump sendmail. QMail is much faster at SMTP. Ok. Factors you may need to consider: If this is a newsletter, why not use something like ezmlm or majordomo? Are these individualized messages (custom inserts for names or email addresses, custom unsubscribes, etc.)? The messages will be individualized. Hence we would need to send out individual emails. Its possible that the BCC way also will not work, because we would need to process each email individually before sending them out. What would be the best way to handle this ? Many other programmers will mention things like having a dedicated outbound- SMTP machine, while fending the bounces and unsubscribes on another, hardware types (SCSI over IDE), etc. Make sure you have thought your application needs through before beginning programming. I can get a dedicated SMTP machine. That should be ok. Thanks for your input mate.
