proc_open



exemple # exemple avec proc_open(). array("pipe", "r"), stdin est un pipe où le processus va lire => array("pipe", "w"), stdout est un pipe où le processus va écrire => array("file", "/tmp/erroroutput.txt", "a") stderr est un fichier ); $cwd = '/tmp'; $env = array('quelques_options'  $process = proc_open($process_cmd, $descriptorspec, $pipes, $cwd, $env, $options);. if (is_resource($process)) {. echo stream_get_contents($pipes[]);. fclose($pipes[]);. it is important that you close any pipes before calling. proc_close in order to avoid a deadlock. $return_value = proc_close($process);. there are many ways we can interact with other applications from php and share data; there's web services, message queuing systems, sockets, temporary files, exec() , etc. well, today i'd like to show you one approach in particular, proc_open() . the function spawns a new command but with open file

manuel php proc_open exécute une commande et ouvre les pointeurs de fichiers pour les entrées sorties. mai your code more or less works for me. time prints its output to stderr so if you're looking for that output, look in your file files/temp/erroroutput.txt . the stdout pipe $pipes[] will only contain the output of the program ./a . my repro: [edanedan tmp]$ cat proc.php <?php $cwd='/tmp'; $descriptorspec = array(   before anyone asks: yes, i am aware there is a plugin for ssh exec calls, but the servers i'm working on don't support it, and are unlikely to do so. there are actually two. the pecl module, which is a pita that most servers don't have installed anyway and phpseclib, a pure php ssh implementation. an example of its use:

use proc_terminate. it is the proper function to kill process started by proc_open(). proc_terminate($status['pid'], );. déc. in these cases, you can get slightly more flexibility by using the proc_open() command and using unix pipes to pass data. with both techniques, you need an array of items you want to process in parallel, and a separate file that can process the item for you. let's say for example, you want to read a bunch of  proc_open() is similar to popen() but provides a much greater degree of control over the program execution. cmd is the command to be executed by the shell. descriptorspec is an indexed array where the key represents the descriptor number and the value represents how php will pass that descriptor to the child process. description. resource proc_open ( string cmd, array descriptorspec, array &pipes [, string cwd [, array env [, array other_options]]] ). proc_open() is similar to popen() but provides a much greater degree of control over the program execution. php introduces pty support for systems with unix ptys. this allows your script to
