How can the character encoding consistency between user input and PHP code be ensured in a web application?

To ensure character encoding consistency between user input and PHP code in a web application, it is important to set the correct character encoding in both the HTML form and the PHP script that processes the input. This can be done by specifying the character encoding in the HTML form using the meta tag <meta charset="UTF-8"> and setting the default character encoding in the PHP script using the header() function. 

// Set the character encoding in the HTML form
&lt;meta charset=&quot;UTF-8&quot;&gt;

// Set the character encoding in the PHP script
header(&#039;Content-Type: text/html; charset=UTF-8&#039;);
