如何将if / else if变成数组？

Question

我必须在某些网址中添加noindex，这是我目前的代码：

<?php if ($metanoindex) { ?>
<meta name="robots" content="noindex,follow" />
<?php } elseif ($_SERVER['REQUEST_URI']=='/dolls/1/bestselling' ) { ?>
<meta name="robots" content="noindex,follow" />
<?php } elseif ($_SERVER['REQUEST_URI']=='/dolls/1/bestselling/30' ) { ?>
<meta name="robots" content="noindex,follow" /> 
<?php } elseif ($_SERVER['REQUEST_URI']=='/dolls/1' ) { ?>
<meta name="robots" content="noindex,follow" /> 
<?php } else { ?>
<meta name="robots" content="index,follow" />
<?php } ?>

我想知道是否有办法制作一系列网址而不是重复＆＃34;否则如果＆＃34;每一次。

Answer 1

尝试以下

<?php
    $arr = array('/dolls/1/bestselling','/dolls/1/bestselling/30','/dolls/1');
    if($metanoindex || in_array($_SERVER['REQUEST_URI'],$arr)){ ?>
      <meta name="robots" content="noindex,follow" /> 
<?php
    }
    else {
?>
      <meta name="robots" content="index,follow" />
<?php } ?>

PHP手册：in_array()

Answer 2

$urls = array('/dolls/1/bestselling', '/dolls/1/bestselling/30', '/dolls/1');
if (in_array($_SERVER['REQUEST_URI'], $urls)) {
    // Insert meta tag here
}
