proc_open 在 foreach 循环中只调用了一次

Question

class CommandExecuter {

const EXEC_FAILED = "EXEC_FAILED";

public function execute($cmd, $sleep, $descriptors, $progressCallback, $progressCallbackParams, $showProgress = false, $callbackTurns = 0) {

    log_out("INFO", basename(__FILE__), "Executing: $cmd");

    // Start execution of $cmd
    if (!($process = proc_open($cmd, $descriptors, $pipes)) || !is_resource($process)) {

        throw new CTException("Unable to execute command:\n$cmd\n", self::EXEC_FAILED);
    }

    // Set the pipes as non-blocking
    if (isset($descriptors[1]) && $descriptors[1]) {

        stream_set_blocking($pipes[1], FALSE);
    }
    if (isset($descriptors[2]) && $descriptors[2]) {

        stream_set_blocking($pipes[2], FALSE);
    }
    if ($callbackTurns) {
        $i = 0;
    }
    // Used to store all output
    $allOut = "";
    $allOutErr = "";

    // Check process status at every turn
    $procStatus = proc_get_status($process);
    while ($procStatus['running']) {

        // Read prog output
        if (isset($descriptors[1]) && $descriptors[1]) {

            $out = fread($pipes[1], 8192);
            $allOut .= $out;
        }

        // Read prog errors
        if (isset($descriptors[2]) && $descriptors[2]) {

            $outErr = fread($pipes[2], 8192);
            $allOutErr .= $outErr;
        }

        // If callback only after N turns
        if ($callbackTurns) {
            if ($i == $callbackTurns) {
                if ($showProgress) {
                    echo ".\n";
                }

                // Call user provided callback.
                // Callback should be an array as per doc here: 
                // http://www.php.net/manual/en/language.types.callable.php
                // Type 3: Object method call
                if (isset($progressCallback) && $progressCallback) {

                    call_user_func($progressCallback, $progressCallbackParams, $allOut, $allOutErr);
                }

                $i = 0;
            }
        } else {

            // Call user provided callback.
            // Callback should be an array as per doc here: 
            // http://www.php.net/manual/en/language.types.callable.php
            // Type 3: Object method call
            if (isset($progressCallback) && $progressCallback) {

                call_user_func($progressCallback, $progressCallbackParams, $allOut, $allOutErr);
            }
        }

        // Get latest status
        $procStatus = proc_get_status($process);

        if ($showProgress) {

            echo ".";
            flush();
        }

        if ($callbackTurns) {

            $i++;
        }

        sleep($sleep);
    }

    if ($showProgress) {
        echo "\n";
    }

    // Process is over
    proc_close($process);

    return array('out' => $allOut, 'outErr' => $allOutErr);
  }

}

以下场景：当我将执行器命令放入 foreach 循环时，执行器仅被调用一次，而 foreach 循环的其余部分已死或永远挂起。

所以怎么了？

这是电话...

$out = $this->executer->execute('some call', 1, array(2 => array("pipe", "w")), false, false, false, 1);

问候萨沙

Answer 1

解决了 class 写入没有错误。我在程序中解决了它。在 cli 上忘记了 -y 强制覆盖参数。

谢谢萨沙
