<p>As well as calling an application’s <a class="reference internal" href="../incoming/controllers.html"><span class="doc">Controllers</span></a>
|

via the URL in a browser they can also be loaded via the command-line

interface (CLI).</p>

<p>It is recommended to use Spark Commands for CLI scripts instead of

calling controllers via CLI.

|

<p>Let’s create a simple controller so you can see it in action. Using your
|
||
text editor, create a file called Tools.php, and put the following code
|
||
in it:</p>
|
||
<div class="highlight-html+php notranslate"><div class="highlight"><pre><span></span><span class="o"><?</span><span class="nx">php</span>
|
||
|
||
<span class="k">namespace</span> <span class="nx">App\Controllers</span><span class="p">;</span>
|
||
|
||
<span class="k">use</span> <span class="nx">CodeIgniter\Controller</span><span class="p">;</span>
|
||
|
||
<span class="k">class</span> <span class="nc">Tools</span> <span class="k">extends</span> <span class="nx">Controller</span>
|
||
<span class="p">{</span>
|
||
<span class="k">public</span> <span class="k">function</span> <span class="nf">message</span><span class="p">(</span><span class="nv">$to</span> <span class="o">=</span> <span class="s1">'World'</span><span class="p">)</span>
|

<span class="p">{</span>
|

<span class="k">return</span> <span class="s2">"Hello </span><span class="si">{</span><span class="nv">$to</span><span class="si">}</span><span class="s2">!"</span> <span class="o">.</span> <span class="nx">PHP_EOL</span><span class="p">;</span>
|
||
<span class="p">}</span>
|
||
<span class="p">}</span>
|
||
</pre></div>
|
||
</div>
|
||
<div class="admonition note">
|
||
<p class="admonition-title">Note</p>
|
||
<p>If you use <a class="reference internal" href="../incoming/routing.html#auto-routing-improved"><span class="std std-ref">Auto Routing (Improved)</span></a>, change the method name to <code class="docutils literal notranslate"><span class="pre">cliMessage()</span></code>.</p>
|
||
</div>
|
||
<p>Then save the file to your <strong>app/Controllers/</strong> directory.</p>
|
||
</section>
|
||
<section id="define-a-route">
|
||
<h3><a class="toc-backref" href="#id3">Define a Route</a><a class="headerlink" href="#define-a-route" title="Permalink to this headline"></a></h3>
|
||
<p>If you use Auto Routing, skip this.</p>
|
||
<p>In your <strong>app/Config/Routes.php</strong> file you can create routes that are only accessible from
|
||
the CLI as easily as you would create any other route. Instead of using the <code class="docutils literal notranslate"><span class="pre">get()</span></code>,
|
||
<code class="docutils literal notranslate"><span class="pre">post()</span></code>, or similar method, you would use the <code class="docutils literal notranslate"><span class="pre">cli()</span></code> method. Everything else
|
||
works exactly like a normal route definition:</p>
|
||
<div class="highlight-html+php notranslate"><div class="highlight"><pre><span></span><span class="o"><?</span><span class="nx">php</span>
|
||
|
||
<span class="nv">$routes</span><span class="o">-></span><span class="na">cli</span><span class="p">(</span><span class="s1">'tools/message/(:segment)'</span><span class="p">,</span> <span class="s1">'Tools::message/$1'</span><span class="p">);</span>
|
||
</pre></div>
|
||
</div>
|
||
<p>For more information, see the <a class="reference internal" href="../incoming/routing.html#command-line-only-routes"><span class="std std-ref">Routes</span></a> page.</p>
|
||
<div class="admonition warning">
|
||
<p class="admonition-title">Warning</p>
|
||
<p>If you enable <a class="reference internal" href="../incoming/routing.html#auto-routing-legacy"><span class="std std-ref">Auto Routing (Legacy)</span></a> and place the command file in <strong>app/Controllers</strong>,
|
||
anyone could access the command with the help of <a class="reference internal" href="../incoming/routing.html#auto-routing-legacy"><span class="std std-ref">Auto Routing (Legacy)</span></a> via HTTP.</p>
|
||
</div>
|
||
</section>
|
||
<section id="run-via-cli">
|
||
<h3><a class="toc-backref" href="#id4">Run via CLI</a><a class="headerlink" href="#run-via-cli" title="Permalink to this headline"></a></h3>
|
||
<p>Now normally you would visit your site using a URL similar to this:</p>
|
||
<div class="highlight-html+php notranslate"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">tools</span><span class="o">/</span><span class="nx">message</span><span class="o">/</span><span class="nx">to</span>
|
||
</pre></div>
|
||
</div>
|
||
<p>Instead, we are going to open Terminal in Mac/Linux or go to Run > “cmd”
|
||
in Windows and navigate to our CodeIgniter project’s web root.</p>
|
||
<div class="highlight-bash notranslate"><div class="highlight"><pre><span></span>$<span class="w"> </span><span class="nb">cd</span><span class="w"> </span>/path/to/project/public
|
||
$<span class="w"> </span>php<span class="w"> </span>index.php<span class="w"> </span>tools<span class="w"> </span>message
|
||
</pre></div>
|
||
</div>
|
||
<p>If you did it right, you should see “Hello World!” printed.</p>
|
||
<div class="highlight-bash notranslate"><div class="highlight"><pre><span></span>$<span class="w"> </span>php<span class="w"> </span>index.php<span class="w"> </span>tools<span class="w"> </span>message<span class="w"> </span><span class="s2">"John Smith"</span>
|
||
</pre></div>
|
||
</div>
|
||
<p>Here we are passing it an argument in the same way that URL parameters
|
||
work. “John Smith” is passed as an argument and output is:</p>
|
||
<div class="highlight-html+php notranslate"><div class="highlight"><pre><span></span><span class="nx">Hello</span> <span class="nx">John</span> <span class="nx">Smith</span><span class="o">!</span>
|
||
</pre></div>
|
||
</div>

<h2><a class="toc-backref" href="#id5">That’s the Basics!</a><a class="headerlink" href="#that-s-the-basics" title="Permalink to this headline"></a></h2>
|
||
<p>That, in a nutshell, is all there is to know about controllers on the
|
||
command line. Remember that this is just a normal controller, so routing
|
||
and <code class="docutils literal notranslate"><span class="pre">_remap()</span></code> works fine.</p>
|
||
<div class="admonition note">
|
||
<p class="admonition-title">Note</p>
|
||
<p><code class="docutils literal notranslate"><span class="pre">_remap()</span></code> does not work with <a class="reference internal" href="../incoming/routing.html#auto-routing-improved"><span class="std std-ref">Auto Routing (Improved)</span></a>.</p>
|
||
</div>
|
||
<p>If you want to make sure running via CLI, check the return value of <a class="reference internal" href="../general/common_functions.html#is_cli" title="is_cli"><code class="xref php php-func docutils literal notranslate"><span class="pre">is_cli()</span></code></a>.</p>
|
||
<p>However, CodeIgniter provides additional tools to make creating CLI-accessible
|
||
scripts even more pleasant, include CLI-only routing, and a library that helps
|
||
you with CLI-only tools.</p>
