【问题描述】:
我正在尝试从 php 脚本运行 php Interactive shell。更具体地说,我希望能够从交互式 shell 调用我的类。
我设法找到了这个
# custom_interactive_shell.php
function proc($command, &$return_var = null, array &$stderr_output = null)
{
$return_var = null;
$stderr_output = [];
$descriptorspec = [
// Must use php://stdin(out) in order to allow display of command output
// and the user to interact with the process.
0 => ['file', 'php://stdin', 'r'],
1 => ['file', 'php://stdout', 'w'],
2 => ['pipe', 'w'],
];
$pipes = [];
$process = @proc_open($command, $descriptorspec, $pipes);
if (is_resource($process)) {
// Loop on process until it exits normally.
do {
$status = proc_get_status($process);
// If our stderr pipe has data, grab it for use later.
if (!feof($pipes[2])) {
// We're acting like passthru would and displaying errors as they come in.
$error_line = fgets($pipes[2]);
echo $error_line;
$stderr_output[] = $error_line;
}
} while ($status['running']);
// According to documentation, the exit code is only valid the first call
// after a process is finished. We can't rely on the return value of
// proc_close because proc_get_status will read the exit code first.
$return_var = $status['exitcode'];
proc_close($process);
}
}
proc('php -a -d auto_prepend_file=./vendor/autoload.php');
但它只是不工作,它试图进行交互但冻结了很多,即使在滞后之后它也不能真正正确地执行命令。
例子:
> php custom_interactive_shell.php
Interactive shell
php > echo 1;
Warning: Use of undefined constant eo - assumed 'eo' (this will throw an Error in a future version of PHP) in php shell code on line 1
