How can checking the HTML output of PHP code help in identifying issues with string comparisons, as discussed in the forum thread?

Checking the HTML output of PHP code can help in identifying issues with string comparisons by allowing you to see the actual values being compared and any unexpected characters or whitespace that may be present. This can help in debugging and ensuring that the strings being compared are exactly the same. 

<?php
$string1 = "Hello";
$string2 = "hello";

// Incorrect comparison
if ($string1 == $string2) {
    echo "Strings are equal";
} else {
    echo "Strings are not equal";
}

// Correct comparison with case-insensitive check
if (strcasecmp($string1, $string2) == 0) {
    echo "Strings are equal";
} else {
    echo "Strings are not equal";
}
?>
