Are there any specific PHP coding practices or techniques that can simplify the process of identifying the largest variable among multiple variables?

When trying to identify the largest variable among multiple variables in PHP, one approach is to use the `max()` function, which returns the highest value from a list of arguments. By passing all the variables as arguments to the `max()` function, you can easily determine the largest variable.

$var1 = 10;
$var2 = 20;
$var3 = 15;

$largest = max($var1, $var2, $var3);

echo "The largest variable is: " . $largest;
