如何连接PHP变量以在菜单中使用

Question

I'm not a PHP guy, however I believe PHP can be used to accomplish this.

Basically I'm using the same absolute path in my main menu + /about, /blog etc so figured well my files are already PHP why not use a Var to do this :) (I come from a Flash AS background)

This is what I've tried below, but to no avail :(

<div id="nav_bar">

<?php $athenasweburl = 'http://s433108212.onlinehome.us/'; ?>

<ul class="nav">
    <li class="<?php echo $page === 'home' ? "selected" : "" ?>"><a href="<?php $athenasweburl; ?>">Home</a></li>
    <li class="<?php echo $page === 'about' ? "selected" : "" ?>"><a href="<?php echo ($athenasweburl+'about'); ?>">About</a></li>
    <li class="<?php echo $page === 'blog' ? "selected" : "" ?>"><a href="<?php $athenasweburl+'blog'; ?>">Blog</a></li>
    <li class="<?php echo $page === 'book' ? "selected" : "" ?>"><a href="<?php $athenasweburl+'book'; ?>">Book</a></li>
    <li class="<?php echo $page === 'events' ? "selected" : "" ?>"><a href="<?php $athenasweburl+'events'; ?>">Events</a></li>
    <li class="<?php echo $page === 'services' ? "selected" : "" ?>"><a href="<?php $athenasweburl+'services'; ?>">Services</a></li>
    <li class="<?php echo $page === 'contact' ? "selected" : "" ?>"><a href="#dialog" name="modal">Contact</a></li>
    <li class="search"><input type="text" onfocus="if(this.value == 'Search') { this.value = ''; }" value="Search" /></li>
    <li class="search_btn"><a href="#" title="Lets find it!"><div class="search_go">Go</div></a></li>
</ul>

thoughts anyone?

In PHP + adds numbers together.. What you looking for is gluing strings.. Replace the + signs with . (dot), and an echo in front of each string, and it should work.

<div id="nav_bar">

<?php
$menu = array("home","about","blog","book","events","services");
function echoListItem($item){
    global $page;
    $url = 'http://s433108212.onlinehome.us/';
    if($item != "home") $url .= $item;
    $selected = $item == $page ? 'selected' : '';
    echo '<li class="'.$selected.'"><a href="'.$url.'">'.ucfirst($item).'</a></li>';
}
?>

<ul class="nav">
    <?php array_walk($menu, 'echoListItem'); ?>
    <li class="<?php echo $page === "contact" ? "selected" : "" ?>"><a href="#dialog" name="modal">Contact</a></li>
    <li class="search"><input type="text" onfocus="if(this.value == 'Search') { this.value = ''; }" value="Search" /></li>
    <li class="search_btn"><a href="#" title="Lets find it!"><div class="search_go">Go</div></a></li>
</ul>

This should do just about the same!
