Unity sql PHP script can log in with wrong password, what's wrong?

The php script reads the database for the correct email, however any password is "correct" according to the script. Do any of you know what needs to be changed in order for it to login with the correct password? Thank you very much!

 <?php
 $Hostname = "localhost";
 $DBName = "accounts";
 $User = "root";
 $PasswordP = "";
 
 mysql_connect($Hostname, $User, $PasswordP) or die("Can't connect into database");
 mysql_select_db($DBName)or die("Can't connect into database");
 
 $Email = $_REQUEST["Email"];
 $Password = $_REQUEST["Password"];
 
 if(!$Email || !$Password)
 {
     echo "Login or password cannnot be empty.";
 }
 else
 {
     $SQL = "SELECT * FROM accounts WHERE Email = '" . $Email . "'";
     $result_id = @mysql_query($SQL) or die("DATABASE ERROR!");
     $total = mysql_num_rows($result_id);
     if($total)
     {
         $datas = @mysql_fetch_array($result_id);
         if (strcmp($Password, $datas["Password"])){
         
          $sql2 = "SELECT Characters FROM accounts WHERE Email = '" . $Email . "'";
          $result_id2 = @mysql_query($sql2) or die("DATABASE ERROR!");
          while($row = mysql_fetch_array($result_id2))
          {
                 echo $row['Characters'];
                 echo":";
                 echo"Success";
          }
     }
     
     else
     {
         echo "WrongPassword";
     }
     }
     else
     {
         echo "EmailDoesNotExist";
     }
     }
     
     mysql_close();
     ?>
