title: if( $_GET) if else problem
body: <p>need help...</p>
  
  <p>the getting input form:</p>
  
  <pre><code>&lt;select name="age"&gt;     
  &lt;option value="25-30"&gt;25-30&lt;/option&gt;
  &lt;option value="31-40"&gt;31-40&lt;/option&gt;        
  &lt;option value="41-50"&gt;41-50&lt;/option&gt;
  &lt;option value="51-60"&gt;51-60&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>example url</p>
  
  <pre><code>search/?age=25-30
  </code></pre>
  
  <p>the function php:</p>
  
  <pre><code>if ( $_GET['age'] !="25-30") $age = '("A")'; 
  elseif ( $_GET['age'] !="31-40") $age = '("B")'; 
  elseif ( $_GET['age'] !="41-50") $age = '("C")'; 
  elseif ( $_GET['age'] !="51-60") $age = '("D")'; 
  else ( $_GET['age'] !="25-30") $age = '("A")'; 
  
  $search ="http://domain.com/?q='.$age;
  </code></pre>
  
  <p>the problem: the $age inside $search always returns A (or 25-30) even though i have selected other values (31-40, 41-50, 51-60)</p>
  
  <p>please help..thanks</p>
