PHP向Python脚本传递参数的方法及其实践

<?php

$param1 = 'value1';
$param2 = 'value2';

// 将要传递的参数拼接到 python 的命令后面
$command = "python your_script.py $param1 '$param2'";

// 执行该命令并将输出结果存入变量（注意可能存在的安全性问题）
$output = [];
$return_var = -1;
exec($command, &$output, $return_var);

if ($return_var === 0) {
// 输出来自Python脚本的结果
print_r($output);
} else {
echo 'Error occurred while executing the script.';
}

?>

import sys

# 获取命令行参数
arg1 = sys.argv[1]
arg2 = sys.argv[2]

print(f"Received arguments: {arg1}, {arg2}")
# 进一步基于这些参数完成所需操作...

<?php

$data_to_send = ['key1'=>'val1', 'key2'=> 'val2'];
$temp_file_path = '/tmp/data_for_python.txt';

file_put_contents($temp_file_path, json_encode($data_to_send));

// 下面这步不是必须但建议加上，通知Python进程有新数据可消费
touch('/path/to/some/watched/file.marker');

?>
