== operator is not giving true even when strings are same

Question

Here is my code:

$param = $old_password.$salt;
$hashed_password = $this->general->hash($param);
//echo $hashed_password;echo " "; echo $userdata->password;exit;
if($hashed_password == $userdata->password){
    print_r("com");exit;
}
print_r("didn't match");exit;

when I echo as above result is

8fb9ccf75da3c0eb285d3dddd80895a8f15f64d5 8fb9ccf75da3c0eb285d3dddd80895a8f15f64d5

which is exactly same. But it doesn't enters into the if statement.

You are using wrong way to compare string. You need to compare string using `strcmp()` function, check my answer. — Naim Malek, Oct 31 '17 at 12:21

Try var_dump() on both variables. Maybe you have empty spaces somewhere.

And if that doesn't solve your problem either try using the "===" operator – Sergiu Vintu Oct 31 '17 at 11:55
Yeah, there is one extra space on th data that came from database. How would that come? – Tekraj Shrestha Oct 31 '17 at 12:00
It depends on the database,but sometimes strings get reformated to have a certain length. – Sergiu Vintu Oct 31 '17 at 12:05

Compare string using strcmp() function

$param = $old_password.$salt;
$hashed_password = $this->general->hash($param);
if (strcmp($hashed_password, $userdata->password) == 0) {
    echo "matched"; exit;
}else{
    echo "didn't match"; exit;
}

Try This

         // $param=$old_password.$salt;
         $hashed_password = $this->general->hash($param);
         $password = $userdata->password;
         //echo $hashed_password;echo " "; echo $userdata->password;exit;
         if($hashed_password == $password)
         {
          print_r("com");exit;
         }else
         {
            print_r("didn't match");exit;   
         }
