在PHP中调用Python脚本有多种方法,以下是一些常见的方法:

  1. 使用 exec()shell_exec() 函数:
<?php
$command = "python3 /path/to/your/script.py";
exec($command, $output, $return_var);

if ($return_var === 0) {
    echo "Output: " . implode("\n", $output);
} else {
    echo "Error: " . $return_var;
}
?>
  1. 使用 system() 函数:
<?php
$command = "python3 /path/to/your/script.py";
$output = system($command);
echo "Output: " . $output;
?>
  1. 使用 passthru() 函数:
<?php
$command = "python3 /path/to/your/script.py";
passthru($command);
?>
  1. 使用 proc_open() 函数:
<?php
$command = "python3 /path/to/your/script.py";
$process = proc_open($command, [0 => ["pipe", "r"], 1 => ["pipe", "w"], 2 => ["pipe", "w"]], $pipes);

if (is_resource($process)) {
    fclose($pipes[0]);
    $output = stream_get_contents($pipes[1]);
    fclose($pipes[1]);
    $error_output = stream_get_contents($pipes[2]);
    fclose($pipes[2]);
    proc_close($process);

    if ($error_output) {
        echo "Error: " . $error_output;
    } else {
        echo "Output: " . $output;
    }
} else {
    echo "Failed to start the process.";
}
?>
  1. 使用 popen()pclose() 函数:
<?php
$command = "python3 /path/to/your/script.py";
$process = popen($command, "r");

if ($process) {
    while (!feof($process)) {
        echo fread($process, 4096);
    }
    pclose($process);
} else {
    echo "Failed to start the process.";
}
?>

请注意,这些方法可能会受到PHP配置的限制,例如safe_modedisallow_exec()。确保在调用这些函数之前检查PHP配置。
