Connect pipes of processes in php

阅读更多关于 Connect pipes of processes in php

问题 I would like the output of one process created with proc_open to be piped to another one created with proc_open (in php). For example. In bash I can do: [herbert@thdev1 ~]$ cat foo 2 3 1 [herbert@thdev1 ~]$ cat foo | sort 1 2 3 [herbert@thdev1 ~]$ I would like to simulate this in php using proc_open (instead of shell_exec) in order to have control over return-codes, pipes, etc. So I want something like this: $catPipes=array(); $sortPipes=array(); $cwd = '/tmp'; $env = array(); $catProcess =

Multiple input with proc_open()

问题 I'm currently working on an online program. I'm writing a php script that executes a command in the command line with proc_open() (under Linux Ubuntu). This is my code so far: <?php $cmd = "./power"; $descriptorspec = array( 0 => array("pipe", "r"), 1 => array("pipe", "w"), 2 => array("pipe", "w"), ); $process = proc_open($cmd, $descriptorspec, $pipes); if (is_resource($process)) { fwrite($pipes[0], "4"); fwrite($pipes[0], "5"); fclose($pipes[0]); while($pdf_content = fgets($pipes[1])) { echo

PHP using proc_open so that it doesn't wait for the script it opens (runs) to finish?

阅读更多关于 PHP using proc_open so that it doesn't wait for the script it opens (runs) to finish?

问题 I've spent a while on this but can't get this to work, I apologize as I asked a somewhat related question about this earlier but deleted it so I could do more research to narrow down the question, at this point I am stuck as I thought I had the solution with this but its not working as I expect.. I found a forum where someone asked a similar question and they gave code like below, which I am trying.. it does run the script, but it still waits for it to finish before going to the next line in

Sending signals to a process opened by proc_open()

阅读更多关于 Sending signals to a process opened by proc_open()

问题 We've got a utility here that's using proc_open() to call ssh to run commands on a remote machine. However, in some cases we need to halt the command on the remote machine but proc_close() and proc_terminate() do not cause the desired signal to be sent through to the far side of the ssh connection. SSH will generally issue a SIGHUP to running programs when it is terminated, but we need to send a SIGINT to ssh which will forward it through to the program running on the remote end. I've googled

问题 I have a problem passing environment variables to processes that i opened with proc_open. I found the following example on http://us2.php.net/manual/en/function.proc-open.php <?php $descriptorspec = array( 0 => array("pipe", "r"), // stdin is a pipe that the child will read from 1 => array("pipe", "w"), // stdout is a pipe that the child will write to 2 => array("file", "/tmp/error-output.txt", "a") // stderr is a file to write to ); $cwd = '/tmp'; $env = array('some_option' => 'aeiou');

Not getting entire response from popen

问题 Hi I'm running a process with popen;- $handle = popen('python scriptos.py', "r"); while (!feof($handle)) { $data = fgets($handle); echo "> ".$data; } And I'm only getting 3 lines from a process that returns 5 lines. I run this exact command in CLi and I will get more response. It's as if it stops reading early (it can take time to complete and updates the next 2 lines whilst working, it's a progress indicator). Am I doing anything wrong? Is proc_open more suitable (i've started seeing if I

Proper shell execution in PHP

阅读更多关于 Proper shell execution in PHP

问题 The problem I was using a function that made use of proc_open() to invoke shell commands. It seems the way I was doing STDIO was wrong and sometimes caused PHP or the target command to lock up. This is the original code: function execute($cmd, $stdin=null){ $proc=proc_open($cmd,array(0=>array('pipe','r'),1=>array('pipe','w'),2=>array('pipe','w')),$pipes); fwrite($pipes[0],$stdin); fclose($pipes[0]); $stdout=stream_get_contents($pipes[1]); fclose($pipes[1]); $stderr=stream_get_contents($pipes

Run perl file from PHP script but not wait for output on Windows Server

阅读更多关于 Run perl file from PHP script but not wait for output on Windows Server

Im trying to execute a perl script from within a php script. I have had this working using various methods such as exec, popen and proc_open but I have a couple of issues to get around which the good old Google isnt giving me the answers to. I need to run the .pl script (passing one variable to the script which is a number) from within the php file but stop the php script from waiting until the .pl has finished (the .pl is likely to take 4-5 hours to run on the server). Im not expecting any return output from the perl script (the perl script logs its output to a mysql db) so I just need it to
