我已经尝试了很多次flush()使脚本同步工作，脚本只打印第一个命令“gcloud compute ssh yellow”和“ls -la”的数据，我希望让脚本在每次执行时打印输出fputs()。

<?php

$descr = array( 0 => array('pipe','r',),1 => array('pipe','w',),2 => array('pipe','w',),);
$pipes = array();
$process = proc_open("gcloud compute ssh yellow", $descr, $pipes);

if (is_resource($process)) {
    sleep(2);
    $commands = ["ls -la", "cd /home", "ls", "sudo ifconfig", "ls -l"];     
    foreach ($commands as $command) {    
        fputs($pipes[0], $command . " \n");
        while ($f = fgets($pipes[1])) {
            echo $f;
        }
    }
    fclose($pipes[0]);  
    fclose($pipes[1]);
    while ($f = fgets($pipes[2])) {
        echo "\n\n## ==>> ";
        echo $f;
    }
    fclose($pipes[2]);
    proc_close($process);

}

提前致谢

我相信问题是您等待输入的循环。fgets只有遇到EOF才会返回false。否则，它返回它读取的行；因为包含换行符，所以它不会返回任何可以类型转换为 false 的内容。您可以改用stream_get_line()它，它不会返回 EOL 字符。请注意，这仍然需要您的命令在其输出后返回一个空行，以便它可以评估为 false 并中断 while 循环。

<?php
$prog     = "gcloud compute ssh yellow";
$commands = ["ls -la", "cd /home", "ls", "sudo ifconfig", "ls -l"];
$descr    = [0 => ['pipe','r'], 1 => ['pipe','w'], 2 =>['pipe','w']];
$pipes    = [];
$process  = proc_open($prog, $descr, $pipes);

if (is_resource($process)) {
    sleep(2);
    foreach ($commands as $command) {
        fputs($pipes[0], $command . PHP_EOL);
        while ($f = stream_get_line($pipes[1], 256)) {
            echo $f . PHP_EOL;
        }
    }
    fclose($pipes[0]);
    fclose($pipes[1]);
    fclose($pipes[2]);
    proc_close($process);
}

另一种选择是在循环外收集输出，尽管如果您需要知道什么输出来自什么命令，这将需要您解析输出。

<?php
$prog     = "gcloud compute ssh yellow";
$commands = ["ls -la", "cd /home", "ls", "sudo ifconfig", "ls -l"];
$descr    = [0 => ['pipe','r'], 1 => ['pipe','w'], 2 =>['pipe','w']];
$pipes    = [];
$process  = proc_open($prog, $descr, $pipes);

if (is_resource($process)) {
    sleep(2);
    foreach ($commands as $command) {
        fputs($pipes[0], $command . PHP_EOL);
    }
    fclose($pipes[0]);
    $return = stream_get_contents($pipes[1]);
    $errors = stream_get_contents($pipes[2]);
    fclose($pipes[1]);
    fclose($pipes[2]);
    proc_close($process);
}
