How can one disable case sensitivity in PHP variables and comparisons, and what are the implications of doing so?

To disable case sensitivity in PHP variables and comparisons, you can use the strtolower() function to convert all strings to lowercase before performing any comparisons. This ensures that comparisons are case-insensitive and variables are treated uniformly regardless of their case. 

$var1 = "Hello";
$var2 = "hello";

if(strtolower($var1) == strtolower($var2)) {
    echo "Variables are equal";
} else {
    echo "Variables are not equal";
}
