PHP for the Web is a terrific introduction on how to use modern PHP effectively. While there is a lot of material out there about building applications with PHP, most of them focus on using a framework like Laravel or Symfony. By working with pure PHP, you will be able to focus on the core ideas instead of how a particular framework implements them.

In this course, you will learn how to use multiple web technologies like POST requests, forms, sessions, and redirects to build a CRUD application with an authentication system.

By the end, you will have all the ingredients at your disposal to go out and build stunning, dynamic PHP web applications.

PHP for the Web: Learn PHP without a Framework

If you don’t explicitly set a `method` attribute on an HTML `form` element, a `POST` request will be made when submitting the form.


<p>If you don’t explicitly set a <code>method</code> attribute on an HTML <code>form</code> element, a <code>POST</code> request will be made when submitting the form.</p>


Only at the beginning of each PHP script that produces an HTML page based on user input

Only when all the HTML has been `echo`-ed

Every time you `echo` user input as part of the HTML page

Where should you use the function `htmlspecialchars`?

<p>Where should you use the function <code>htmlspecialchars</code>?</p>


If the `method` attribute of an HTML `form` element has been set to `post`, and you have a text field named `city`, you can get the submitted value from `[...]`.

<p>If the <code>method</code> attribute of an HTML <code>form</code> element has been set to <code>post</code>, and you have a text field named <code>city</code>, you can get the submitted value from <code>[...]</code>.</p>


Is this the correct way to select the option of the HTML `select` element that the user has submitted?

 ~~~~~~~~php
       
<select name="country">
     <?php if ($_POST['country'] === 'NL'){ ?>
        <option value="NL">NL</option> 
     <?php } ?>
     
</select>
~~~~~~~~

<p>Is this the correct way to select the option of the HTML <code>select</code> element that the user has submitted?</p>
<pre><code class="language-php">      
&lt;select name=&quot;country&quot;&gt;
    &lt;?php if ($_POST['country'] === 'NL'){ ?&gt;
       &lt;option value=&quot;NL&quot;&gt;NL&lt;/option&gt; 
    &lt;?php } ?&gt;
    &lt;!-- and so on --&gt;
&lt;/select&gt;
</code></pre>
