proc_terminate - Kills a process opened by proc_open

SYNOPSIS

       bool proc_terminate (resource  $process, [int  $signal = 15])

DESCRIPTION

	Signals  a $process (created using proc_open(3)) that it should terminate. proc_terminate(3) returns immediately and does not wait for the
       process to terminate.

       proc_terminate(3) allows you terminate the process and continue with other tasks. You may poll the process (to see if it has  stopped  yet)
       by using the proc_get_status(3) function.

PARAMETERS

	      o $process
		- The proc_open(3) resource that will be closed.

	      o $signal
		-  This  optional  parameter  is only useful on POSIX operating systems; you may specify a signal to send to the process using the
		kill(2) system call. The default is SIGTERM.

RETURN VALUES

	Returns the termination status of the process that was run.

popen - Opens process file pointer

SYNOPSIS

       resource popen (string  $command, string  $mode)

DESCRIPTION

	Opens a pipe to a process executed by forking the command given by $command.

PARAMETERS

	      o $command
		- The command

	      o $mode
		- The mode

RETURN VALUES

	Returns  a file pointer identical to that returned by fopen(3), except that it is unidirectional (may only be used for reading or writing)
       and must be closed with pclose(3). This pointer may be used with fgets(3), fgetss(3), and fwrite(3). When the mode  is  'r',  the  returned
       file pointer equals to the STDOUT of the command, when the mode is 'w', the returned file pointer equals to the STDIN of the command.

	If an error occurs, returns FALSE.

EXAMPLES

       Example #1

	      popen(3) example

	      <?php
	      $handle = popen("/bin/ls", "r");
	      ?>

	If  the  command  to  be  executed  could not be found, a valid resource is returned. This may seem odd, but makes sense; it allows you to
       access any error message returned by the shell:

       Example #2

	      popen(3) example

	      <?php
	      error_reporting(E_ALL);

	      /* Add redirection so we can get stderr. */
	      $handle = popen('/path/to/executable 2>&1', 'r');
	      echo "'$handle'; " . gettype($handle) . "
";
	      $read = fread($handle, 2096);
	      echo $read;
	      pclose($handle);
	      ?>

NOTES

       Note

	       If you're looking for bi-directional support (two-way), use proc_open(3).

       Note

	      When safe mode is enabled, you can only execute files within the safe_mode_exec_dir. For practical  reasons,  it	is  currently  not
	      allowed to have .. components in the path to the executable.

       Warning

	      With safe mode enabled, the command string is escaped with escapeshellcmd(3). Thus, echo y | echo x becomes echo y | echo x.
