等於多個字符串我發現了類似對這個問題的東西,但它是不相關的字符串。我只是在尋找寫下面代碼的最佳方式,我認爲必須有一些我不知道的簡短版本。如果變量在導航列表

<ul id="top-nav"> 
    <li <?php if($filename == "index.php"){echo ("class=\"current\"");} ?>><a href="index.php" title="Home">Home</a></li> 
    <li <?php if($filename == "cause.php"){echo ("class=\"current\"");} ?>><a href="cause.php" title="Cause">Cause</a></li> 
    <li><a href="order.php" title="Order">Order</a></li> 
    <li class="drop-down<?php if($filename == "grand-prize-one.php" | $filename == "grand-prize-two.php"){echo (" current");} ?>"><a href="grand-prize-one.php" title="Grand Prizes">Grand Prizes</a> 
     <ul> 
     <li><a href="grand-prize-one.php" title="Grand Prize One">Grand Prize One</a></li> 
     <li><a href="grand-prize-two.php" title="Grand Prize Two">Grand Prize Two</a></li> 
     </ul> 
    </li> 
    <li <?php if($filename == "early-bird.php"){echo ("class=\"current\"");} ?>><a href="early-bird.php" title="Early Bird">Early Bird</a></li> 
    <li class="drop-down<?php if($filename == "vehicles.php" || $filename == "vacations.php" || $filename == "other-prizes.php"){echo (" current");} ?>"><a href="vehicles.php" title="Electronics &amp; more">Other Prizes</a> 
     <ul> 
     <li><a href="vehicles.php" title="Vehicles">Vehicles</a></li> 
     <li><a href="vacations.php" title="Vacations">Vacations</a></li> 
     <li><a href="other-prizes.php" title="Electronics &amp; more">Electronics &amp; more</a></li> 
     </ul> 
    </li> 
    <li <?php if($filename == "winners.php"){echo ("class=\"current\"");} ?>><a href="winners.php" title="Winners">Winners</a></li> 
    </ul> 

是否有寫$filename == "vehicles.php" || $filename == "vacations.php" || $filename == "other-prizes.php"較短的方法嗎?我懷疑我會需要它來適應更多的5-10個可能的字符串。

謝謝

SOLUTION

對於那些誰發現了這個問題,我最後做的:

隨着我的主要PHP

<?php 
// My other code 
$grandPrizes = array("grand-prize-one.php","grand-prize-two.php"); 
$otherPrizes = array("vehicles.php","vacations.php","other-prizes.php"); 
?> 

我的直列PHP中的li元素

<?php if (in_array($filename, $grandPrizes)) {echo " current";} ?> 
+0

請使用||而不是|進行或比較。 – eisberg 2011-03-23 15:15:18

||是一個邏輯運算符,|是一個按位運算符 – 2011-03-23 15:21:22

+0

哦,哇。謝謝。我不知道。我不知道我從哪裏得到這些信息,但它對我來說總是有效的。只是好奇,爲什麼它工作?如果任一$ a或$ b爲真 – 2011-03-23 15:22:21

$filenames = array("vehicles.php","vacations.php","other-prizes.php"); 
if (in_array($filename, $filenames)) { 
    // code here 
}

你可以使用

if(in_array($filename, array("vehicles.php", "vacations.php", "other-prizes.php"))){

試試這個:

<?php 
    if(in_array($filename, array("vehicles.php", "vacations.php", "other-prizes.php")) { 
     echo ("class=\"current\""); 
    } 
?> 

in_array功能適用於你正在嘗試做的。
