    copied!<p>In your case, I would solve it like this:</p> <pre><code>&lt;? function get_current( $nav_page ) { $uri = $_SERVER['REQUEST_URI']; return ( $uri == $nav_page ) ? ' id="current" ' : ''; } ?&gt; </code></pre> <p>And small changes in HTML:</p> <pre><code>&lt;ul&gt; &lt;li &lt;?= get_current('/') ?&gt; &gt;&lt;a&gt;HOME&lt;/a&gt;&lt;/li&gt; &lt;li &lt;?= get_current('/page1.php') ?&gt; &gt;&lt;a&gt;PAGE 1&lt;/a&gt;&lt;/li&gt; &lt;li &lt;?= get_current('/page2.php') ?&gt; &gt;&lt;a&gt;PAGE 2&lt;/a&gt;&lt;/li&gt; &lt;li &lt;?= get_current('/page3.php') ?&gt; &gt;&lt;a&gt;PAGE 3&lt;/a&gt;&lt;/li&gt; &lt;li &lt;?= get_current('/page4.php') ?&gt; &gt;&lt;a&gt;PAGE 4&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; </code></pre> <p>Please note that I changed the parameters to absolute URLs because <code>$_SERVER['REQUEST_URI']</code> contains absolute path.</p> <h2>EDIT:</h2> <p>Since you used <code>func_get_args()</code>, you might be going to accept arbitrary number of 'page-name.php' as parameter for <code>get_current()</code>. In that case, the <code>get_current</code> function becomes:</p> <pre><code>function get_current() { $uri = $_SERVER['REQUEST_URI']; if ( in_array( $uri, func_get_args() ) ) return ' id="current" '; return ''; } </code></pre> <p>and its accompanying HTML:</p> <pre><code>&lt;li &lt;?= get_current('/', '/index.php')?&gt; &gt; ... &lt;/li&gt; </code></pre> <h2>EDIT2:</h2> <p>Your <code>$_SERVER['REQUEST_URI']</code> shows that files are in the <code>/new/</code> folder. Changed the logic to compare end-parts. </p> <pre><code>&lt;? function get_current( $nav_page ) { $uri = $_SERVER['REQUEST_URI']; return is_rear_match( $uri, $nav_page ) ? ' id="current" ' : ''; } function is_rear_math( $haystack, $needle ) { $rear = substr($haystack, -strlen($needle)); return $rear !== false &amp;&amp; $rear === $needle; } ?&gt; </code></pre> <p>HTML:</p> <pre><code>&lt;ul&gt; &lt;li &lt;?= get_current('/') ?&gt; &gt;&lt;a&gt;HOME&lt;/a&gt;&lt;/li&gt; &lt;li &lt;?= get_current('/page1.php') ?&gt; &gt;&lt;a&gt;PAGE 1&lt;/a&gt;&lt;/li&gt; &lt;li &lt;?= get_current('/page2.php') ?&gt; &gt;&lt;a&gt;PAGE 2&lt;/a&gt;&lt;/li&gt; &lt;li &lt;?= get_current('/page3.php') ?&gt; &gt;&lt;a&gt;PAGE 3&lt;/a&gt;&lt;/li&gt; &lt;li &lt;?= get_current('/page4.php') ?&gt; &gt;&lt;a&gt;PAGE 4&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; </code></pre>
