PHP回显HTML页面内容无法正常工作

Question

I am trying to use the following php code to display another html page. Sadly nothing is printed on the screen, and yes I have checked and confirmed that the link works. Any thoughts on why this could be happening would be helpful thank you.

$site = readfile("http://k9minecraft.tk/thanks.html");
echo $site;

Answer 1

First, make sure php is configured so that allow_url_fopen is on.

If you want to save the string to a variable, try using file_get_contents instead since it adds the file to memory. Refer file_get_contents for more detailed information on official documentation.

$site = file_get_contents("http://k9minecraft.tk/thanks.html");
echo $site;

The readfile function reads the file directly to the output buffer, so it doesn't require an echo. Refer readfile for more detailed information on official documentation.

readfile("http://k9minecraft.tk/thanks.html");

readfile is more efficient in terms of memory usage, whereas file_get_contents more useful in many situations.
