title: simple problem in php
body: <pre><code>&lt;?php 
  
  $n1=$_POST['mont'];
  echo $n1;
  if($n1==07)
      echo "numeric";
  if($n1=="07")
      echo "string";
  if($n1==08)
      echo "numeric";
  
  if($n1=="08")
      echo "string";
  ?&gt;
  </code></pre>
  
  <p>in this if $_POST["mont"] is 07
   the output is both string and integer
  but if $_POST["mont"] is 08
  the output is only string</p>
  
  <p>what may be the cause</p>
