title: Output v$session (from oracle DB) in php code
body: <p>I am using oracle db and I want to output the count of v$session in my php code. But when I run it, php reads it as a variable because of "$". Can anyone help me? Thanks!</p>
  
  <p>This is my code:</p>
  
  <pre><code>        $sql = "select COUNT(*) SID from v$session";   
          $array = oci_parse($conn, $sql);
          oci_execute($array);
  
          $row = oci_fetch_array($array);
          echo $row;
  </code></pre>
  
  <p>Error: 
        Notice: Undefined variable: session in C:\xampp\htdocs\test\index.php on line 12</p>
