[mikehaertl/php-shellcommand] A library for invoking external command operations

It provides a simple method interface to call and manipulate external commands, which can be used to replace exec.

Compared with calling exec directly, it has the following features:

• Support environment variables and other parameters
• Support for pipeline resources, such as files or streams

Advanced usage

Add parameter

addArg('--name=', "d'Artagnan");// Add argument with several values// results in --keys key1 key2$command->addArg('--keys', array('key1','key2'));

String input

setStdIn('{"foo": 0}');if (!$command->execute()) {echo $command->getError();} else {echo $command->getOutput();}// Output:// {// "foo": 0// }

Use file content as input

setStdIn($fh);if (!$command->execute()) {echo $command->getError();} else {echo $command->getOutput();}fclose($fh);

setStdIn($fh);if (!$command->execute()) {echo $command->getError();} else {echo $command->getOutput();}fclose($fh);

Encapsulate the command

 '/usr/local/bin/mycommand',// Will be passed as environment variables to the command'procEnv' => array('DEMOVAR' => 'demovalue'),// Will be passed as options to proc_open()'procOptions' => array('bypass_shell' => true,),));
