-<h1>CodeIgniter URLs<a class="headerlink" href="#codeigniter-urls" title="Permalink to this headline">¶</a></h1>
-<p>By default, URLs in CodeIgniter are designed to be search-engine and
-human friendly. Rather than using the standard “query string” approach
-to URLs that is synonymous with dynamic systems, CodeIgniter uses a
-<strong>segment-based</strong> approach:</p>
-<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">news</span><span class="o">/</span><span class="nx">article</span><span class="o">/</span><span class="nx">my_article</span>
-</pre></div>
-</div>
-<div class="admonition note">
-<p class="first admonition-title">Note</p>
-<p class="last">Query string URLs can be optionally enabled, as described
-below.</p>
-</div>
-<div class="section" id="uri-segments">
-<h2>URI Segments<a class="headerlink" href="#uri-segments" title="Permalink to this headline">¶</a></h2>
-<p>The segments in the URL, in following with the Model-View-Controller
-approach, usually represent:</p>
-<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">class</span><span class="o">/</span><span class="nx">function</span><span class="o">/</span><span class="nx">ID</span>
-</pre></div>
-</div>
-<ol class="arabic simple">
-<li>The first segment represents the controller <strong>class</strong> that should be
-invoked.</li>
-<li>The second segment represents the class <strong>function</strong>, or method, that
-should be called.</li>
-<li>The third, and any additional segments, represent the ID and any
-variables that will be passed to the controller.</li>
-</ol>
-<p>The <a class="reference internal" href="../libraries/uri.html"><span class="doc">URI Library</span></a> and the <a class="reference internal" href="../helpers/url_helper.html"><span class="doc">URL Helper</span></a> contain functions that make it easy to work
-with your URI data. In addition, your URLs can be remapped using the
-<a class="reference internal" href="routing.html"><span class="doc">URI Routing</span></a> feature for more flexibility.</p>
-</div>
-<div class="section" id="removing-the-index-php-file">
-<h2>Removing the index.php file<a class="headerlink" href="#removing-the-index-php-file" title="Permalink to this headline">¶</a></h2>
-<p>By default, the <strong>index.php</strong> file will be included in your URLs:</p>
-<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>
-</pre></div>
-</div>
-<p>If your Apache server has <em>mod_rewrite</em> enabled, you can easily remove this
-file by using a .htaccess file with some simple rules. Here is an example
-of such a file, using the “negative” method in which everything is redirected
-except the specified items:</p>
-<div class="highlight-apache"><div class="highlight"><pre><span></span><span class="nb">RewriteEngine</span> <span class="k">On</span>
-<span class="nb">RewriteCond</span> %{REQUEST_FILENAME} !-f
-<span class="nb">RewriteCond</span> %{REQUEST_FILENAME} !-d
-<span class="nb">RewriteRule</span> ^(.*)$ index.php/$1 [L]
-</pre></div>
-</div>
-<p>In the above example, any HTTP request other than those for existing
-directories and existing files is treated as a request for your index.php file.</p>
-<div class="admonition note">
-<p class="first admonition-title">Note</p>
-<p class="last">These specific rules might not work for all server configurations.</p>
-</div>
-<div class="admonition note">
-<p class="first admonition-title">Note</p>
-<p class="last">Make sure to also exclude from the above rule any assets that you
-might need to be accessible from the outside world.</p>
-</div>
-</div>
-<div class="section" id="adding-a-url-suffix">
-<h2>Adding a URL Suffix<a class="headerlink" href="#adding-a-url-suffix" title="Permalink to this headline">¶</a></h2>
-<p>In your <strong>config/config.php</strong> file you can specify a suffix that will be
-added to all URLs generated by CodeIgniter. For example, if a URL is
-this:</p>
-<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>
-</pre></div>
-</div>
-<p>You can optionally add a suffix, like <strong>.html,</strong> making the page appear to
-be of a certain type:</p>
-<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>
-</pre></div>
-</div>
-</div>
-<div class="section" id="enabling-query-strings">
-<h2>Enabling Query Strings<a class="headerlink" href="#enabling-query-strings" title="Permalink to this headline">¶</a></h2>
-<p>In some cases you might prefer to use query strings URLs:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">?</span><span class="nx">c</span><span class="o">=</span><span class="nx">products</span><span class="o">&amp;</span><span class="nx">m</span><span class="o">=</span><span class="nx">view</span><span class="o">&amp;</span><span class="nx">id</span><span class="o">=</span><span class="mi">345</span>
-</pre></div>
-</div>
-<p>CodeIgniter optionally supports this capability, which can be enabled in
-your <strong>application/config.php</strong> file. If you open your config file you’ll
-see these items:</p>
-<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>
-<span class="nv">$config</span><span class="p">[</span><span class="s1">&#39;controller_trigger&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;c&#39;</span><span class="p">;</span>
-<span class="nv">$config</span><span class="p">[</span><span class="s1">&#39;function_trigger&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;m&#39;</span><span class="p">;</span>
-</pre></div>
-</div>
-<p>If you change “enable_query_strings” to TRUE this feature will become
-active. Your controllers and functions will then be accessible using the
-“trigger” words you’ve set to invoke your controllers and methods:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">?</span><span class="nx">c</span><span class="o">=</span><span class="nx">controller</span><span class="o">&amp;</span><span class="nx">m</span><span class="o">=</span><span class="nx">method</span>
-</pre></div>
-</div>
-<div class="admonition note">
-<p class="first admonition-title">Note</p>
-<p class="last">If you are using query strings you will have to build your own
-URLs, rather than utilizing the URL helpers (and other helpers
-that generate URLs, like some of the form helpers) as these are
-designed to work with segment based URLs.</p>
