php 对接midjourney

要在PHP中对接Midjourney API进行文本转图片，可以使用以下示例代码：

$api_url = "https://api.midjourney.com/api/v1/image/generate";
$data = array(
    "text" => "Hello, world!",
    "width" => 600,
    "height" => 400,
    "font_size" => 30,
    "font_family" => "serif",
    "bg_color" => "#f8f8f8"
);
$options = array(
    "http" => array(
        "method" => "POST",
        "header" => "Content-Type: application/json\r\n",
        "content" => json_encode($data)
    )
);
$context = stream_context_create($options);
$response = file_get_contents($api_url, false, $context);
file_put_contents("output.png", $response);

以上代码使用了PHP内置函数`file_get_contents()`发起POST请求，将API返回的图片保存到名为`output.png`的文件中。你可以根据自己的需求修改`$data`参数。
