<p>You are encouraged to use this function any time you need to generate a

<p>This function returns the same thing as <a class="reference internal" href="#site_url" title="site_url"><code class="xref php php-func docutils literal"><span class="pre">site_url()</span></code></a>, without
|
|||
|
the <em>index_page</em> or <em>url_suffix</em> being appended.</p>
|
|||
|
<p>Also like <a class="reference internal" href="#site_url" title="site_url"><code class="xref php php-func docutils literal"><span class="pre">site_url()</span></code></a>, you can supply segments as a string or
|
|||

an array. Here is a string example:</p>
|
|||
|
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nx">base_url</span><span class="p">(</span><span class="s2">"blog/post/123"</span><span class="p">);</span>

|
</pre></div>
|

|
</div>
|
|||
|
<p>The above example would return something like:
|
|||
|
<em>http://example.com/blog/post/123</em></p>
|
|||
|
<p>This is useful because unlike <a class="reference internal" href="#site_url" title="site_url"><code class="xref php php-func docutils literal"><span class="pre">site_url()</span></code></a>, you can supply a
|
|||
|
string to a file, such as an image or stylesheet. For example:</p>
|
|||
|
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nx">base_url</span><span class="p">(</span><span class="s2">"images/icons/edit.png"</span><span class="p">);</span>
|
|||
|
</pre></div>
|
|||
|
</div>
|

|
<p>This would give you something like:
|

|
<em>http://example.com/images/icons/edit.png</em></p>

<p>This function is an alias for <code class="docutils literal"><span class="pre">CI_Config::base_url()</span></code>. For more info,

<p>Does a “header redirect” to the URI specified. If you specify the full
|
|||
|
site URL that link will be built, but for local links simply providing
|
|||
|
the URI segments to the controller you want to direct to will create the
|
|||
|
link. The function will build the URL based on your config file values.</p>
|
|||
|
<p>The optional second parameter allows you to force a particular redirection
|
|||
|
method. The available methods are <strong>auto</strong>, <strong>location</strong> and <strong>refresh</strong>,
|
|||
|
with location being faster but less reliable on IIS servers.
|
|||
|
The default is <strong>auto</strong>, which will attempt to intelligently choose the
|
|||
|
method based on the server environment.</p>
|
|||
|
<p>The optional third parameter allows you to send a specific HTTP Response
|
|||
|
Code - this could be used for example to create 301 redirects for search
|
|||
|
engine purposes. The default Response Code is 302. The third parameter is
|

<em>only</em> available with <strong>location</strong> redirects, and not <em>refresh</em>. Examples:</p>
