How does the behavior of htmlspecialchars() differ between the <head> and <body> sections of HTML in PHP?

When using the htmlspecialchars() function in PHP to escape special characters in HTML, it is important to consider where the output will be placed. In the <head> section of HTML, certain characters like "<" and ">" are not allowed and should be encoded differently than in the <body> section. To handle this, you can use the ENT_QUOTES flag for the <head> section and the ENT_HTML5 flag for the <body> section when calling htmlspecialchars(). 

// For &lt;head&gt; section
$escaped_head = htmlspecialchars($unescaped_text, ENT_QUOTES);

// For &lt;body&gt; section
$escaped_body = htmlspecialchars($unescaped_text, ENT_HTML5);
