How can you escape characters in PHP to avoid conflicts with HTML attributes?

To escape characters in PHP to avoid conflicts with HTML attributes, you can use the htmlspecialchars function. This function converts special characters like <, >, ", ', and & into their HTML entity equivalents, preventing them from being interpreted as HTML code. By using htmlspecialchars, you can safely output data from PHP variables into HTML attributes without causing any conflicts. 

&lt;?php
// Example variable containing data to be outputted
$data = &#039;&lt;script&gt;alert(&quot;Hello!&quot;);&lt;/script&gt;&#039;;

// Escaping the data to avoid conflicts with HTML attributes
$escaped_data = htmlspecialchars($data);

// Output the escaped data within an HTML attribute
echo &#039;&lt;div data-content=&quot;&#039; . $escaped_data . &#039;&quot;&gt;&lt;/div&gt;&#039;;
?&gt;
