php asynchronous calls to improve the user experience
Advertisements
Case: PHP language of a SNS communities in the system, users give their friends (the number of hundreds of friends) to send the message, the content of each message varies, sent after the prompt has been sent!
PHP wording used
sendmail.php
<?php
$count=count($emailarr);//$emailarr Mail address of the array to a friend
for($i=0;$i<$count;$i++)
{
sendmail(.....);// Send mail
}
echo '' Sent ';
?>
Assuming that the time to send 100 messages. This operation there will be the result?
User Experience: User Wait -> send out dozens of messages -> system returns an error message out of this operation because of the need to send a large number of messages, leading to php execution time is too long, restless wait for the user. When the apache or nginx to wait more than allow the execution time, return time-out error. This time the user does not clear the success of this operation in the end, in the end sent a few emails.
We can see the code the user experience very poor and can not be successfully completed task.
That should be how does it work?
A concept mentioned here, asynchronous implementation of the user experience: users waiting for -> Send complete friends would ask, how to link the lack of letters?
OK, sent a letter link to the user submits the request, the letter task was transferred to a separate letter of the php processing procedure, when users see the "send complete" when in fact, not sending the letter, this time, letter program is hard work with the background, sending out a letter of
sendmail.php
<?php
$domain="www.***.com";
$url="/system_mail.php";
$par="email=".implode(',',$emailarr)."&........";
$header = "POST $url HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($par) . "\r\n\r\n";
$fp = @fsockopen ($domain, 80, $errno, $errstr, 30);
fputs ($fp, $header . $par);
fclose($fp);
echo '' Sent ';
?>
system_mail.php
<?php
ini_set("ignore_user_abort",true);
ignore_user_abort(true);// Code here need open PHP.ini options , Ensure the PHP implementation does not timeout , Not understand that reference my another article " After you close the browser, PHP scripts will continue to run "
/*
Get email addresses , Letters, here is a letter code
*/
?>
Well, into the asynchronous mode, the user submits the information, you can immediately get the result "has been sent." Believed it would send a letter in the background, until the completion of this article sent from php enthusiasts http://www.phplover.cn/ , the original address: http://www.phplover.cn/post/phpyibugongzuotishengyonghutiyan. html
