  • PHP send batch email [closed]

    - by qalbiol
    Possible Duplicate: Sending mass email using PHP I have a PHP script that sends an individual email to all users in my DB, such as a monthly / weekly newsletter. The code I am using goes as follows: $subject = $_POST['subject']; $message = $_POST['message']; // Get all the mailing list subscribers. $query = $db->prepare("SELECT * FROM maildb"); $query->execute(); // Loop through all susbcribers, and send and individual email. foreach ($query as $row) { // Setting maximum time limit to infinite. set_time_limit(0); $newMessage = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> </head> <body>'; // Search for the [unsubscribe] tag and replace it with a URL for the user to unsubscribe $newMessage .= str_replace("[unsubscribe]", "<a href='".BASE_URL."unsubscribe/".$row['hash']."/".$row['email']."'>unsubscribe</a>", $message); $newMessage .= '</body></html>'; $to = $row['email']; // Establish content headers $headers = "From: [email protected]"."\n"; $headers .= "Reply-To: [email protected]"."\n"; $headers .= "X-Mailer: PHP v.". phpversion()."\n"; $headers .= "MIME-Version: 1.0"."\n"; $headers .= "Content-Type: text/html; charset=iso-8859-1"."\n"; $headers .= "Content-Transfer-Encoding: 8bit;"; mail($to, $subject, $newMessage, $headers); // Send email to each individual user } This code works perfectly with a REALLY small database... I recently populated my test db with 200k+ users, and obviously this script fails, gets out of memory, and dies... I know this is a bad way to send so many emails, thats why I'd like to ask you for much more efficient ways to do this! Thank you very much!

  • What should I learn & use to become a pro in PHP & Python Web development?

    - by pecker
    Hello, I'll just show some code to show how I do web development in PHP. <html> <head> <title>Example #3 TDavid's Very First PHP Script ever!</title> </head> <? print(Date("m/j/y")); require_once("somefile.php"); $mysql_db = "DATABASE NAME"; $mysql_user = "YOUR MYSQL USERNAME"; $mysql_pass = "YOUR MYSQL PASSWORD"; $mysql_link = mysql_connect("localhost", $mysql_user, $mysql_pass); mysql_select_db($mysql_db, $mysql_link); $result = mysql_query("SELECT impressions from tds_counter where COUNT_ID='$cid'", $mysql_link); if(mysql_num_rows($result)) { mysql_query("UPDATE tds_counter set impressions=impressions+1 where COUNT_ID='$cid'", $mysql_link); $row = mysql_fetch_row($result); if(!$inv) { print("$row[0]"); } } ?> <body> </body> </html> Thats it. I write every file like this. Recently, I learnt OOP and started using classes & objects in PHP. I hear that there are many frameworks there for PHP. They say that one must use these libraries. But I feel they are just making things complicated. Anyway, this is how I've been doing my web development. Now, I want to improve this. and make it professional. Also I want to move to Python. I searched SO archives and found everyone suggesting Django. But, can any one give me some idea about how web development in Python works? user (client) request for page --- webserver(-embedded PHP interpreter) ---- Server side(PHP) Script --- MySQL Server. Now, is it that instead of PHP interpreter there is python interpreter & instead of php script there is python script, which contains both HTML & python (embedded in some kind of python tags). Python script connects to database server and fetches some data which will be printed as HTML. or is it different in python world? Is this Django thing like frameworks for PHP? Can't one code in python without using Django. Because, I never encountered any post without django Please give me some kick start.

  • Responsive width for iPhone

    - by Alex Marchant
    This is my first time building a responsive site, and as I tailor the CSS for the iPhone I'm running into a problem. The styles all apply correctly, the text changes size and the wrapper changes widths. The problem is the iPhone browser still opens up at a huge width, see the screenshot: I'm using @media all and (max-device-width: 480px) {} to set the specific iPhone css. body {width:;} doesn't work. Thanks for the help :)

  • C++: Initialization Order for Member Classes

    - by Nikhil
    In the following code, when the ctor of X is called will the ctor of A or B be called first? Does the order in which they are placed in the body of the class control this? If somebody can provide a snippet of text from the C++ standard that talks about this issue, that would be perfect. class A; class B; class X { private: A a; B b; }
