PHP->bash->python 输出

Question

<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
passthru("bash /var/www/html/init.sh 2>&1",$pass_result);
echo $pass_result; 
?>

我无法在 PHP 级别获得 python 结果。 python 脚本 print("string") 到 bash 脚本，如果我

#!/bin/sh
START=$(python3 /usr/lib/cgi-bin/test.py)
echo "${START}"

这样做，如果我运行 bash 脚本，它会在终端上输出字符串 但如果我从 PHP 调用它，它会立即结束 错误：

#PHP OUTPUT
/usr/lib/python3/dist-packages/requests/__init__.py:89:

如果我在这段代码中放置一段时间和一个 for 行为变得很奇怪，

#!/bin/sh
START=python3 /usr/lib/cgi-bin/test.py &
BACK_PID=$!
while kill -0 $BACK_PID ; do
        for (( i=0; i<10; i++ )); do
            sleep 5
            echo "WTF" $i
        done
    echo "${OUTPUT}"
done

bash 脚本将在 for 循环的大约 8 次迭代中获得 python 字符串的输出，直接在终端上运行它，这是我得到的唯一方法PHP 等待 bash 脚本结束，并返回所有 9 WTF，但没有 python 字符串，我不明白为什么它没有到达 PHP。
