How does the use of utf8_decode() impact the display of special characters in PHP?

When special characters are displayed incorrectly in PHP, it may be due to encoding issues. Using utf8_decode() can help convert UTF-8 encoded strings to ISO-8859-1, which may resolve the problem and display special characters correctly. 

// Example code snippet using utf8_decode() to display special characters correctly
$string = "Special characters like é, ü, and ñ";
$decoded_string = utf8_decode($string);
echo $decoded_string;
