对file_get_contents进行异常捕获

        项目中，需要用到调用其他组的接口，目前这边就封装了个函数来实现

function file_get_contents_post($url, $post)
{
    $options = array(
        "http" => array(
            "method" => "POST",
            "header"  => "Content-type: application/x-www-form-urlencoded",
            "content" => http_build_query($post),
        ),
    );

    $result = file_get_contents($url, false, stream_context_create($options));

    return $result;
}

function run()
{
    set_error_handler(
        create_function(
            "$severity, $message, $file, $line",
            "throw new ErrorException($message, $severity, $severity, $file, $line);"
        )
    );
    
    try {
        file_get_contents_post("http://url/", []);
    }
    catch (Exception $e) {
        echo $e->getMessage();
    }

    restore_error_handler();
}

run();
