 ＆lt;？php 
 
 $ url =”http://en.wikipedia.org/wiki/Pakistan  “; 
 $ ch = curl_init（urlencode（$ url））; 
 echo $ ch;

Remove the urlencode call.

答

remove the urlencode($url) it should be:

 $ch = curl_init($url);

答

Well.

If you remove urlencode() with instantiating your $ch-var, you go just fine. urlencode() is definitely wrong here.

Good:

 $ch = curl_init($url);

Bad:

 $ch = curl_init(urlencode($url));

答

$ch = curl_init($url);

instead of

$ch = curl_init(urlencode($url));
