title: What is the meaning of []
body: <p>I have a code as below and I am not sure what type of data variable <code>$ACTIVITYGROUPS[]</code> has and how do I read it ?</p>
  
  <pre><code>$ACTIVITYGROUPS[] = saprfc_table_read ($fce, "ACTIVITYGROUPS", $i);
  </code></pre>
  
  <p>When I did <code>print_r(saprfc_table_read ($fce, "ACTIVITYGROUPS", $i);</code> I got bunch of arrays without any seperator and not sure how to exactract the data. can someone tell me what does it do in above sentences ?</p>
  
  <p>Here is what <code>print_r(saprfc_table_read ($fce, "ACTIVITYGROUPS", $i);</code> result gives me:</p>
  
  <pre><code>Array (

      [FROM_DAT] =&gt; 20080813
      [TO_DAT] =&gt; 99991231
      [AGR_TEXT] =&gt; Security Display - Users &amp; Roles
      [ORG_FLAG] =&gt; C
  )
  
  Array (
      [AGR_NAME] =&gt; Y:SECURITY_ADMIN_COMMON

      [TO_DAT] =&gt; 99991231
      [AGR_TEXT] =&gt; Security Administrator
      [ORG_FLAG] =&gt; C
  )
  
  Array (
