用PHP实现基本if和elseif语句

Posted 2021-02-25

if:
 
<?php if ($foo == 'yes') { ?>
   do something
<?php } if ($bar == 'no') { ?>
   do something else
<?php } ?>
 
 
else/if:
 
<?php if ($foo == 'surething') { ?>
   do this
<?php } else { ?>
   do everything else
<?php } ?>
 
else/if variation:
 
<a class="<?php if ($foo == 'righto') { ?>
   selected
<?php } else { ?>
   hoverBtn
<?php } ?>" href="contact.php"><span>Contact</span></a>
