PHP，如果其他所有以该域开头的URL，则执行其他操作

I want an example in php with if then else, that is

lets say a variable have a value containing URL

so

if the URL starts with a cetrain URL www.blabla.com/... then do something

else

if the URL start with www.whateverurl.com/... then do something else ,,

I hope its clear enough Guys, please some help,

My PHP code with the embedded HTML is like that. How can I avoid all the cases and have just one if and one else and not have elseif?

<?php if ($item->getPrimaryLink()) : ?></br>

   <?php if ($item->getPrimaryLink()->getUrl() == "http://www.blabla.com/index.php/article?id=3200") : ?></br>                

         <a href="<?php echo $item->getPrimaryLink()->getUrl(); ?>" class="readon"><span><?php rc_e('READ_MORE'); ?></span></a>

        <?php elseif ($item->getPrimaryLink()->getUrl() == "http://www.blabla.com/index.php/article?id=1508") : ?></br>

         <a href="<?php echo $item->getPrimaryLink()->getUrl(); ?>" class="readon"><span><?php rc_e('READ_MORE'); ?></span></a>

        <?php elseif ($item->getPrimaryLink()->getUrl() == "http://www.blabla.com/index.php/article?id=1840") : ?></br>

         <a href="<?php echo $item->getPrimaryLink()->getUrl(); ?>" class="readon"><span><?php rc_e('READ_MORE'); ?></span></a> 

        <?php elseif ($item->getPrimaryLink()->getUrl() == "http://www.blabla.com/index.php/article?id=2541") : ?></br>

         <a href="<?php echo $item->getPrimaryLink()->getUrl(); ?>" class="readon"><span><?php rc_e('READ_MORE'); ?></span></a>       

 <?php else : ?></br>

        <a href="<?php echo $item->getPrimaryLink()->getUrl(); ?>" class="modal" rel="{size: {x: 1024, y: 550}, handler:'iframe'}"><span><?php rc_e('READ_MORE'); ?></span></a>           

<?php endif; ?>

Thank you all and any ideas or suggestions would be really appreciated.

You can use switch() statement.

    switch ($item->getPrimaryLink()->getUrl()) {
        case "http://www.blabla.com/index.php/article?id=3200":
            echo "<a href=". $item->getPrimaryLink()->getUrl()." class='readon'><span>". rc_e('READ_MORE'). "</span></a>";
            break;
        case "http://www.blabla.com/index.php/article?id=1508":
            echo "<a href=". $item->getPrimaryLink()->getUrl()." class='readon'><span>". rc_e('READ_MORE')."</span></a>";
            break;
        ...
    }

Use the explode() function to get the first part of your url.

<?php 

    $url= $item->getPrimaryLink(); // www.blabla.com/index.php?id=123 <- The slash would be your divider in this case.
    $url_ex= explode("/", $url); 

    // So now you have
    //$url_ex[0] = 'www.blabla.com';
    //$url_ex[1] = 'index.php?id=123';
?>



 <?php if ($item->getPrimaryLink()) : ?></br>
        <?php if ($url_ex[0] == 'www.blabla.com'){

            echo "<a href=". $item->getPrimaryLink()->getUrl()." class='readon'><span>". rc_e('READ_MORE'). "</span></a>";
    }
 <?php else : ?></br>

        <a href="<?php echo $item->getPrimaryLink()->getUrl(); ?>" class="modal" rel="{size: {x: 1024, y: 550}, handler:'iframe'}"><span><?php rc_e('READ_MORE'); ?></span></a>           

<?php endif; ?>

I think you can use something similar to this.
