通过双向通信,您可以访问stdin,stdout和stderr的最接近的等价物是

proc_open().

以下是文档中的示例：

$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');

$process = proc_open('php', $descriptorspec, $pipes, $cwd, $env);

if (is_resource($process)) {

// $pipes now looks like this:

// 0 => writeable handle connected to child stdin

// 1 => readable handle connected to child stdout

// Any error output will be appended to /tmp/error-output.txt

fwrite($pipes[0], '<?php print_r($_ENV); ?>');

fclose($pipes[0]);

echo stream_get_contents($pipes[1]);

fclose($pipes[1]);

// It is important that you close any pipes before calling

// proc_close in order to avoid a deadlock

$return_value = proc_close($process);

echo "command returned $return_value\n";

}

?>

如果您只需要stdout和stdin,则可以使用popen().

这是我修改过的例子,因为手册很糟糕：

$handle = popen('/path/to/executable', 'r');

$lines = [];

while (!feof($handle))

{

$lines[] = fgets($handle);

}

pclose($handle);

这将把/ path / to / executable的输出读入一行输出行.

你还询问了逃避争论的问题.您可以使用escapeshellarg()执行此操作：

$escapedArg = escapeshellarg($arg);
