What is the difference between 'Male' and 'male' in PHP?

In PHP, 'Male' and 'male' are treated as different values due to case sensitivity. If you want to compare or manipulate these values without considering their case, you can use functions like strtolower() or strtoupper() to convert them to a common case before performing any operations. 

$value1 = 'Male';
$value2 = 'male';

// Convert both values to lowercase
$value1_lower = strtolower($value1);
$value2_lower = strtolower($value2);

// Now you can compare the values without considering case
if($value1_lower == $value2_lower) {
    echo "Values are equal regardless of case.";
} else {
    echo "Values are not equal.";
}
