Are there any best practices for handling boolean values when reading from configuration files in PHP?

When reading boolean values from configuration files in PHP, it's important to handle them correctly to avoid unexpected behavior. One common approach is to use strict comparisons (===) when checking boolean values to ensure they are properly evaluated. Additionally, it's a good practice to explicitly cast the values to boolean using the (bool) or (boolean) casting operators. 

// Read boolean value from configuration file
$configValue = true; // Example value read from config file

// Cast the value to boolean
$booleanValue = (bool) $configValue;

// Check the boolean value using strict comparison
if ($booleanValue === true) {
    echo "Boolean value is true";
} else {
    echo "Boolean value is false";
}
