Are there any specific PHP functions or methods that can help avoid errors when dealing with special characters in strings?

Special characters in strings can cause errors when not properly handled, especially when dealing with encoding or escaping issues. To avoid these errors, PHP provides functions like htmlspecialchars() and htmlentities() to encode special characters in a string, making it safe to output in HTML. These functions convert characters like <, >, ", ', and & to their corresponding HTML entities, preventing any potential security vulnerabilities or display issues. 

$string = &quot;This is a string with special characters like &lt; and &gt;&quot;;
$encoded_string = htmlspecialchars($string, ENT_QUOTES, &#039;UTF-8&#039;);
echo $encoded_string;
