当尝试读取上面带有fopen的URL上显示的.txt文件时，它返回无法打开流：无效的参数。

我已尝试过urlencode，但它会出现同样的错误

Answer 1

首先，如果您尝试打开urlencode($url)，则可以访问

这无效。

其次，您的$myfile是resource。所以你需要使用它，例如：

$url = "https://www.google.co.uk/s?tbm=map&fp=1&gs_ri=maps&suggest=p&authuser=0&hl=en&pb=!2i14!4m12!1m3!1d36371.595804441626!2d-2.4949300500000002!3d53.74963355!2m3!1f0!2f0!3f0!3m2!1i1600!2i740!4f13.1!7i10!10b1!12m6!2m3!5m1!2b0!20e3!10b1!16b1!19m10!1e1!1e13!1e2!1e5!1e3!1e10!1e12!1e15!1e27!4smaps_sv.tactile!20m49!1e1!1e13!1e2!1e5!1e11!1e4!1e3!1e10!1e12!1e15!1e27!2m2!1i203!2i100!3m1!2i4!5smaps_sv.tactile!6m3!1m2!1i86!2i86!7m26!1m3!1e1!2b0!3e3!1m3!1e2!2b1!3e2!1m3!1e2!2b0!3e3!1m3!1e3!2b0!3e3!1m3!1e4!2b0!3e3!1m3!1e3!2b1!3e2!2b1!4b1!9b0!22m3!1sJf4OVtPaHMj-UL_-hugD!3b1!7e81!23m1!4b1!26m9!1e12!1e15!1e13!1e3!1e27!2m2!1i80!2i80!4smaps_sv.tactile!37m1!1e81&q=downing%20street&pf=p&tch=1&ech=14&psi=Jf4OVtPaHMj-UL_-hugD.1443823133674.1";
$myfile = fopen(($url), "r") or die("Unable to open file!");
echo stream_get_contents($myfile);
fclose($myfile);

或只是

echo file_get_contents($url);
