<h2>Tips and Notes</h2>

<p><b>Tip:</b> You can assign only one array to the array_multisort() function, or as many as you like.</p>
<p><b>Note:</b> String keys will be maintained, but numeric keys will be re-indexed, starting at 0 and increase by 1.</p>
<p><b>Note:</b> You can assign the sorting order and the sorting type parameters after each array. 
If you don't, each array parameter uses the default values.</p>

<hr />

<h2>Example 1</h2>

<table class="ex" cellspacing="0" border="1" width="100%">
  <tr>
    <td>
    <pre>&lt;?php
$a1=array(&quot;Dog&quot;,&quot;Cat&quot;);
$a2=array(&quot;Fido&quot;,&quot;Missy&quot;);
array_multisort($a1,$a2);
print_r($a1);
print_r($a2);
?&gt;</pre>
    </td>
</tr>
</table>

<p>The output of the code above will be:</p>

<table class="ex" cellspacing="0" border="1" width="100%">
  <tr>
    <td>
    <pre>Array ( [0] => Cat [1] => Dog )
Array ( [0] => Missy [1] => Fido ) </pre>
    </td>
</tr>
</table>
<br />
<hr />

<h2>Example 2</h2>

<p>See how it sorts when two values are the same:</p>

<table class="ex" cellspacing="0" border="1" width="100%">
  <tr>
    <td>
    <pre>&lt;?php
$a1=array(&quot;Dog&quot;,&quot;Dog&quot;,&quot;Cat&quot;);
$a2=array(&quot;Pluto&quot;,&quot;Fido&quot;,&quot;Missy&quot;);
array_multisort($a1,$a2);
print_r($a1);
print_r($a2);
?&gt;</pre>
    </td>
</tr>
</table>

<p>The output of the code above will be:</p>

<table class="ex" cellspacing="0" border="1" width="100%">
  <tr>
    <td>
    <pre>Array ( [0] => Cat [1] => Dog [2] => Dog ) 
Array ( [0] => Missy [1] => Fido [2] => Pluto )</pre>
    </td>
</tr>
</table>
<br />
<hr />

<h2>Example 3</h2>

<p>With sorting parameters:</p>

<table class="ex" cellspacing="0" border="1" width="100%">
  <tr>
    <td>
    <pre>&lt;?php
$a1=array(&quot;Dog&quot;,&quot;Dog&quot;,&quot;Cat&quot;);
$a2=array(&quot;Pluto&quot;,&quot;Fido&quot;,&quot;Missy&quot;);
array_multisort($a1,SORT_ASC,$a2,SORT_DESC);
print_r($a1);
print_r($a2);
?&gt;</pre>
    </td>
</tr>
</table>

<p>The output of the code above will be:</p>

<table class="ex" cellspacing="0" border="1" width="100%">
  <tr>
    <td>
    <pre>Array ( [0] => Cat [1] => Dog [2] => Dog )
Array ( [0] => Missy [1] => Pluto [2] => Fido )</pre>
    </td>
</tr>
