Hello,
In an effort to resolve a different issue, I am trying to confirm that
my stack is capable of servicing at least two simultaneous requests for
a given PHP script.
In an effort to confirm this, I have written a simple PHP script that
runs for a specified period of time and outputs the number of seconds
elapsed since the script was started.
-----------------------------------------------
<?php
$start = time();
echo 'Starting concurrency test. Seconds elapsed:' . PHP_EOL;
flush();
$elapsed = time() - $start;
echo $elapsed . PHP_EOL;
flush();
while ($elapsed < 60) {
echo time() - $start . PHP_EOL;
flush();
sleep(5);
$elapsed = time() - $start;
}
echo time() - $start . PHP_EOL;
flush();
-----------------------------------------------
For whatever reason, nginx *always* buffers the output, even when I set
output_buffering = off
in the effective php.ini, *and* I set
fastcgi_keep_conn on;
in my nginx.conf.
Of course, when I request the script via the command-line (php -f), the
output is not buffered.
Is it possible to disable PHP output buffering completely in nginx?
Thanks for any help!
-Ben
