title: array_push into a multidimensional array (append a value to cell)
body: <p>This is my code :</p>
  
  <pre><code>$cars = array(
      array("Volvo" , '22,18,'),
      array("BMW" , '15,13'),
      array("Saab", '5,2' ),
      array("Land Rover", '17,15' )
  );
  
  print_r($cars);
  </code></pre>
  
  <p>this is the output :</p>
  
  <pre><code>Array ( [0] =&gt; Array ( [0] =&gt; Volvo [1] =&gt; 22,18, ) [1] =&gt; Array ( [0] =&gt; BMW [1] =&gt; 15,13 ) [2] =&gt; Array ( [0] =&gt; Saab [1] =&gt; 5,2 ) [3] =&gt; Array ( [0] =&gt; Land Rover [1] =&gt; 17,15 ) ) 
  </code></pre>
  
  <p>I want to dynamically push values into (for example) the string numeric values inside that multidimensional array but not overwrite the existed cell (as the same as you append to string $string .= $string.' + Extra Content';)</p>
  
  <p>for example this is the original :</p>
  
  <pre><code>array("Volvo" , '22,18,'),
  </code></pre>
  
  <p>lets add '21,'
  and later
  lets add '27,'
  and later
  lets add '14,'</p>
  
  <p>DYNAMICALLY under that specific cell.</p>
  
  <p>so by the end of the day it would be :</p>
  
  <pre><code>array("Volvo" , '22,18,21,27,14,')
  </code></pre>
  
  <p>Is that possible ?</p>
