Load .profile with proc_open ()
Here's the situation: I wrote a back-end application that runs on a specific server. There is a script on this server that can be executed from an external server, over ssh. My script then checks to see if the environment variables it needs are loaded correctly because I rely heavily on them in the script itself.
This works, although not the way I want it to work. When the connection is established, the. / profile isn't loaded, but using exec('source /home/user/.profile');
doesn't work of course. Since the script is already running. This is why the script starts like this:
#!/to/php/bin/php -n
<?php
if (!$_SERVER['VAR_FROM_PROFILE'])
{
exec('/absolute/path/to/helperscript '.implode(' ',$argv),$r,$s);
if ($s !== 0)
{
die('helper script fails: '.$s);
}
exit($r[0]);
}
This script helper is ksh-script:
#!/path/ksh
source /.profile
$*
Loading the profile and calling the first script again. I want this second script to go away, I find it silly ... it takes a second script to run the first. I know it is possible to set environment values with proc_open, but rewriting .profile as a souds array is even more foolish. I also tried proc_open
shell, load the profile and run the script again from within itself. Only to find that the script keeps calling itself makes me believe the profile isn't loaded at all.
Here's my attempt:
#!/to/php/bin/php -n
<?php
if (!$_SERVER['VAR_FROM_PROFILE'] && $argv[1] !== 'fromself')
{
$res = proc_open('ksh',array(array('pipe','r'),array('pipe','w'),array('pipe','w')),$pipes);
usleep(5);
fwrite($pipes[0],'source /home/user/.profile & '.$argv[0].' fromself');
fclose($pipes[0]);//tried using fflush and a second fwrite. It failed, too
usleep(1);
echo stream_get_contents($pipes[1]);
fclose($pipes[1]);
proc_close($res);
exit();
}
var_dump($_SERVER);
?>
I am still out of luck, can anyone tell me that I forgot something? What am I doing wrong? Did I forget something?

I have not ksh
, but I managed to do it with bash
.
/home/galymzhan/.bash_profile
export VAR_FROM_PROFILE="foobar"
/home/galymzhan/test.php
#!/usr/bin/php -n
<?php
if (!isset($_SERVER['VAR_FROM_PROFILE'])) {
$descriptors = array(0 => array('pipe', 'r'), 1 => array('pipe', 'w'));
$process = proc_open('bash', $descriptors, $pipes);
fwrite($pipes[0], escapeshellcmd('source /home/galymzhan/.bash_profile') . "\n");
fwrite($pipes[0], escapeshellcmd('/home/galymzhan/test.php') . "\n");
fclose($pipes[0]);
echo "Output:\n";
echo stream_get_contents($pipes[1]);
echo "\n";
fclose($pipes[1]);
proc_close($process);
exit;
}
print "Got env var {$_SERVER['VAR_FROM_PROFILE']}\n";
// Useful part of the script begins
Output:
[galymzhan@dinohost ~]$ ./test.php
Output:
Got env var foobar
