How can escaping characters and meta tags help resolve character encoding issues in PHP?

Escaping characters and using meta tags can help resolve character encoding issues in PHP by ensuring that the data is properly encoded and displayed. Escaping characters involves using functions like htmlspecialchars() to convert special characters into HTML entities, preventing them from causing encoding issues. Additionally, setting the correct meta tags in the HTML document header, such as <meta charset="UTF-8">, can specify the character encoding used in the document. 

// Escaping characters using htmlspecialchars()
$unsafe_string = &quot;Hello, &lt;script&gt;alert(&#039;XSS attack&#039;);&lt;/script&gt;&quot;;
$safe_string = htmlspecialchars($unsafe_string, ENT_QUOTES, &#039;UTF-8&#039;);

// Setting meta tag for character encoding
echo &quot;&lt;!DOCTYPE html&gt;&quot;;
echo &quot;&lt;html&gt;&quot;;
echo &quot;&lt;head&gt;&quot;;
echo &quot;&lt;meta charset=&#039;UTF-8&#039;&gt;&quot;;
echo &quot;&lt;title&gt;Character Encoding Example&lt;/title&gt;&quot;;
echo &quot;&lt;/head&gt;&quot;;
echo &quot;&lt;body&gt;&quot;;
echo &quot;&lt;p&gt;$safe_string&lt;/p&gt;&quot;;
echo &quot;&lt;/body&gt;&quot;;
echo &quot;&lt;/html&gt;&quot;;
