Same function needs to be called simultaneously for all users in php -

-

i have start_processing("set 1") function takes 6 hrs complete set1,

i want process set 2, set 3 .... how can process of them in same time ?? since when put

<?php start_processing("set1"); start_processing("set2"); start_processing("set3"); ?>

it takes 18 hrs.

i want complete process in 6hrs processing.

finally got solution

i have take curl_multi - far better. save handshakes - not needed every time!

use curl_multi_init run processes in parallel. can have tremendous effect.

unless using php apache-module, can use pcntl_fork create several processes of each processes 1 function call.

if(pcntl_fork())     start_processing("set1"); else if(pcntl_fork())     start_processing("set2"); else     start_processing("set3");

if have varying number of working sets, put them in array , loop through it. bear in mind many processes overload system!

another, more lightweight, option use of php pthreads afaik work apache, require installing corresponding php-extension first.

a third possibility is, mentioned sandeep_kosta , niranjan n raju, create 1 cronjob each working set.

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
