title: Why does this code cause an Expected ")" error?
body: <pre><code>&lt;?php
    $i == array(1, 2); 
    $j == array(a, b); 
    $m == count($j); 
    $n == count($i); 
    for ( $i = 0; $i &lt; $m; i++ ) 
    {
      for ( $j = 0; j &lt; $n; j++) 
      { echo $i."x"$j; }
    }
  ?&gt;
  </code></pre>
  
  <p>The error is referencing line 6: <code>for ( $i = 0; $i &lt; $m; i++ )</code></p>
