The PHP If Statement And The Elseif Clause - Page 2
elseif ($current_month == 2) { $current_image = "image_feb.jpg"; }
// It is February(2), set variable to image_feb.jpg
elseif ($current_month == 3) { $current_image = "image_march.jpg"; }
elseif ($current_month == 4) { $current_image = "image_apr.jpg"; }
elseif ($current_month == 5) { $current_image = "image_may.jpg"; }
elseif ($current_month == 6) { $current_image = "image_june.jpg"; }
elseif ($current_month == 7) { $current_image = "image_july.jpg"; }
elseif ($current_month == 8) { $current_image = "image_aug.jpg"; }
elseif ($current_month == 9) { $current_image = "image_sept.jpg"; }
elseif ($current_month == 10) { $current_image = "image_oct.jpg"; }
elseif ($current_month == 11) { $current_image = "image_nov.jpg"; }
elseif ($current_month == 12) { $current_image = "image_dec.jpg"; }

The rest of the code is a series of elseif clauses which sets the $current_image variable to the image corresponding to the current month. As you can see each elseif clause begins with an "elseif". You can also use the syntax "else if" instead. It is a matter of choice. Next in the statement is the expression to be tested which is between the ( and ). Finally the task to be performed if that expression is true is between the { and }. Did you notice that I did not use a default else clause at the end of the sequence? Now all you need to do is add this PHP code inside your HTML webpage where you wish the image to be displayed. Place the PHP code between the opening PHP tag (<?php) and the closing PHP tag (?>) , change the extension of the webpage to .php or .php3 and upload the twelve images (image_jan.jpg … image_dec.jpg) to your server. Here is the complete code including the default code if no expression is true.
<?php
$current_image = "";
$current_month = date(n);
if ($current_month == 1) { $current_image = "image_jan.jpg"; }
elseif ($current_month == 2) { $current_image = "image_feb.jpg"; }
elseif ($current_month == 3) { $current_image = "image_march.jpg"; }
elseif ($current_month == 4) { $current_image = "image_apr.jpg"; }
elseif ($current_month == 5) { $current_image = "image_may.jpg"; }
elseif ($current_month == 6) { $current_image = "image_june.jpg"; }
elseif ($current_month == 7) { $current_image = "image_july.jpg"; }
elseif ($current_month == 8) { $current_image = "image_aug.jpg"; }
elseif ($current_month == 9) { $current_image = "image_sept.jpg"; }
elseif ($current_month == 10) { $current_image = "image_oct.jpg"; }
elseif ($current_month == 11) { $current_image = "image_nov.jpg"; }
elseif ($current_month == 12) { $current_image = "image_dec.jpg"; }
else { $current_image = "image_default.jpg"; }
