Why is '==' not working in PHP?

Both values are '2' but I am not getting a true. Why?

 echo $getuser. "<br />"; 
 echo $userurl. "<br />"; 
   开发者_JAVA百科if ($getuser == $userurl) {  
       echo "true <br />";
     }

Result

2
2

Instead of echoing them out, use var_dump() to see exactly what is stored in those variables:

var_dump($getuser); echo "<br />";
var_dump($userurl); echo "<br />";

You probably have some stray spaces or other characters which are not easy, or maybe not possible to visually detect.

use

var_dump($getuser);
var_dump($userurl);

Pay attention to the string length. Consider using trim() if needed

may be contain dummy space in that, use like this

 echo $getuser. "<br />"; 
 echo $userurl. "<br />"; 
   if (trim($getuser) == trim($userurl)) {  
       echo "true <br />";
     }

When I try

$getuser = 2;
$userurl = 2;

echo $getuser. "<br />";
echo $userurl. "<br />";
if ($getuser == $userurl) {
    echo "true <br />";
}

Results:

2
2
true 

Works for me. On XAMPP (Windows) and Linux (Apache) alike. So there's problem probably somewhere in configuration or something...
