Implode()
this just concatenate the variables and placed into one single variable for example
<form action=<?php $_php_self; ?> method="post">
<label for="dob">Enter Your date of Birth</label>

<select name="day">Day</option>
<option value="1">sun</option>
<option value="2">mon</option>
</select>
<select value="month">Month
<option value="1">Jan</option>
<option value="2">feb</option>
</select>

<select name="year">year
<option value="2012">2012</option>
<option value="2011">2011</option>
</select>

when sending this value in database in single field then you need to join all the values in single variable that is
$dob= implode(array($_post['day'], $_post['month', $_post['year']));

Then it's just concatenated all these values come from the from into single variable $dob.

Explode()
this is the function that is just reverse of the implode.
that it's just split the value given in one varible into array.
