title: How to access a multidimensional array?
body: <p>I am new to php. I am able to fetch the records from database and storing them into an array. Array contains more than one values for each array index. Now I want to fetch only one value. Here is my array:  </p>
  
  <pre><code>Array ( [0] =&gt; Array ( [center_id] =&gt; 103 [center_strength] =&gt; 800 ) 
          [1] =&gt; Array ( [center_id] =&gt; 102 [center_strength] =&gt; 400 ) 
          [2] =&gt; Array ( [center_id] =&gt; 101 [center_strength] =&gt; 200 ) 
        )
  </code></pre>
  
  <p>From this array I want to get the value of <code>[center_strength]</code> only i.e. only <code>800</code>. Please Help me :)</p>
