  390. <ol class="arabic simple">
  391. <li>The first segment represents the controller <strong>class</strong> that should be

  393. <li>The second segment represents the class <strong>function</strong>, or method, that

  395. <li>The third, and any additional segments, represent the ID and any

  399. with your URI data. In addition, your URLs can be remapped using the

  404. <p>By default, the <strong>index.php</strong> file will be included in your URLs:</p>
  405. <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">news</span><span class="o">/</span><span class="nx">article</span><span class="o">/</span><span class="nx">my_article</span>

  407. </div>
  408. <p>If your Apache server has <em>mod_rewrite</em> enabled, you can easily remove this
  409. file by using a .htaccess file with some simple rules. Here is an example
  410. of such a file, using the “negative” method in which everything is redirected
  411. except the specified items:</p>
  412. <div class="highlight-apache"><div class="highlight"><pre><span></span><span class="nb">RewriteEngine</span> <span class="k">On</span>
  413. <span class="nb">RewriteCond</span> %{REQUEST_FILENAME} !-f
  414. <span class="nb">RewriteCond</span> %{REQUEST_FILENAME} !-d
  415. <span class="nb">RewriteRule</span> ^(.*)$ index.php/$1 [L]
  416. </pre></div>
  417. </div>
  418. <p>In the above example, any HTTP request other than those for existing
  419. directories and existing files is treated as a request for your index.php file.</p>
  420. <div class="admonition note">
  421. <p class="first admonition-title">Note</p>

  432. <p>In your <strong>config/config.php</strong> file you can specify a suffix that will be
  433. added to all URLs generated by CodeIgniter. For example, if a URL is
  434. this:</p>
  435. <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">products</span><span class="o">/</span><span class="nx">view</span><span class="o">/</span><span class="nx">shoes</span>
  436. </pre></div>
  437. </div>
  438. <p>You can optionally add a suffix, like <strong>.html,</strong> making the page appear to
  439. be of a certain type:</p>
  440. <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">products</span><span class="o">/</span><span class="nx">view</span><span class="o">/</span><span class="nx">shoes</span><span class="o">.</span><span class="nx">html</span>

  449. </div>
  450. <p>CodeIgniter optionally supports this capability, which can be enabled in
  451. your <strong>application/config.php</strong> file. If you open your config file you’ll
  452. see these items:</p>
  453. <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$config</span><span class="p">[</span><span class="s1">&#39;enable_query_strings&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="k">FALSE</span><span class="p">;</span>

  458. <p>If you change “enable_query_strings” to TRUE this feature will become
  459. active. Your controllers and functions will then be accessible using the
  460. “trigger” words you’ve set to invoke your controllers and methods:</p>

  466. <p class="last">If you are using query strings you will have to build your own
