What are common challenges faced when integrating HTML code with PHP, especially when dealing with quotation marks?

When integrating HTML code with PHP, a common challenge arises when dealing with quotation marks. This is because PHP uses double quotation marks for string interpolation, which can conflict with HTML attributes that also use double quotes. To solve this issue, you can either escape the double quotes within the HTML attributes using a backslash (\), or you can alternate between single and double quotes for better readability. 

<?php
echo "<input type=\"text\" name=\"username\">";
// or
echo '<input type="text" name="username">';
?>
