How can using outdated HTML tags like <font> affect the functionality of PHP scripts?

Using outdated HTML tags like <font> can affect the functionality of PHP scripts because these tags are no longer supported in modern web development practices. This can lead to issues with styling, responsiveness, and compatibility across different browsers. To solve this issue, it is recommended to use CSS for styling instead of relying on outdated HTML tags. 

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;style&gt;
        /* CSS styling for text color */
        p {
            color: red;
        }
    &lt;/style&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;?php
    // PHP code to output text with red color
    echo &quot;&lt;p&gt;This text will be displayed in red color.&lt;/p&gt;&quot;;
    ?&gt;
&lt;/body&gt;
&lt;/html&gt;
