Well the topic may not sound very explicit. So I'll do my best to explain it here. I have a pull down menu as part of a form, which contains the months of the year. I'm trying to store the value of this form entry using the $_POST['month'] variable into a database but first, I need to convert the month values into their corresponding integer values( that is 1 for January, 2 for February etc), in order to easily do date calculations later down the road. Any ideas about how to do this? It may be helpful to include the code for the pull down menu.

Code: Select all


<p><tab> Date of Birth: <?php //Make the month pull down menu.
							//Array to store months. 
							$months = array (1 => 'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'); 
							print '<select name= "month">';
							foreach ($months as $key => $value) {
							    print "\n<option value=\"$key\">$value</option>";
							}
							print '</select>'; ?> </tab> 
 

							<tab>  <?php //Make the day pull down menu
							print '<select name= "day">';
							for ($day = 1; $day <= 31; $day++) {
							    print "\n<option value=\"$day\">$day</option>";
							}
							print '</select>'; ?> </tab>

							<tab><?php //Make the year pull down menu 
							print '<select name= "year">';
							$start_year = date('Y');
							for ($y = ($start_year - 18); $y >= 1900; $y--) {
							    print "\n<option value=\"$y\">$y</option>";
							}
							print '</select>'; ?> </tab> </p>

That's exactly what you're doing. The $key is the integer and the $value is the text name of the month. Do an echo $_POST['month'] and you will have a number.
