How to fetch a variable (that is a url) into a iframe src?

Question

here is what I'm trying to accomplish:

I have a file called url.php. When I access this file the only thing that shows up is a url.

I wanted to fetch this url and use it as a variable on a iframe in a different page.

Here is what I got:

<?php
$myvar = file_get_contents('http://localhost/url.php');
echo "<iframe src='$myvar' height="1800px" width="1900px" frameborder="0"></iframe>";
?>

But it doesnt seem to be working.

Parse error: syntax error, unexpected T_LNUMBER, expecting

Any suggestions? Thanks

You need to watch your double quotes.

echo "<iframe src='$myvar' height='1800px' width='1900px' frameborder='0'></iframe>";

You also may be having issues since you're using it on localhost:

That seems to work but it loads for a long time and doesnt update the iframe src url. The Src remains blank. – user2479024 Jun 24 '13 at 22:01
Just try `echo $myvar;` and see what comes through. – musicnothing Jun 24 '13 at 22:02
echo $myvar; doesnt show anything. So I assume there is something wrong with the file get contents – user2479024 Jun 24 '13 at 22:05
What happens when you visit the page in a web browser? – musicnothing Jun 24 '13 at 22:10
The page where im getting my var or the page with the loaded script? – user2479024 Jun 24 '13 at 22:12
OK. I updated my answer with a link about using `file_get_contents` on `localhost`. Maybe check that out and see if you need to change something. – musicnothing Jun 24 '13 at 22:15
Thanks for the help. I've uploaded to my host and the problem is still there. – user2479024 Jun 24 '13 at 22:17

When echo'ing with variables inside always double check your quotes.

Try this:

echo "<iframe src='".$myvar."' height='1800px' width='1900px' frameborder='0'></iframe>";

Seems like its not fetching properly the $myvar – user2479024 Jun 24 '13 at 22:07
Then its a problem with `file_get_contents` – Sergio Jun 24 '13 at 22:11
Any suggestion what could be wrong with it? The url.php is displaying a URL as content just fine. – user2479024 Jun 24 '13 at 22:13
Post the content of the url.php, try also having them in the same directory and calling with relative path (without `http://localhost`) – Sergio Jun 24 '13 at 22:46
