PHP : What does mean of []
<p>I have a code as below and I am not sure what type of data valirable $ACTIVITYGROUPS[] 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 (
    [AGR_NAME] =&gt; Y:SECURITY_DISPLAY
    [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
    [FROM_DAT] =&gt; 20080813
    [TO_DAT] =&gt; 99991231
    [AGR_TEXT] =&gt; Security Administrator
    [ORG_FLAG] =&gt; C
)

Array (
    [AGR_NAME] =&gt; Y:LOCAL_TRANSPORT
    [FROM_DAT] =&gt; 20090810
    [TO_DAT] =&gt; 99991231
    [AGR_TEXT] =&gt; Transport into target client - DEV system only
