How can explicit casting help prevent errors related to boolean values in PHP code?

When dealing with boolean values in PHP, explicit casting can help prevent errors by ensuring that the variable is treated as a boolean type. This can be particularly useful when comparing variables or using them in conditional statements, as it avoids unexpected type conversions that could lead to unintended behavior.

// Example of using explicit casting to prevent errors related to boolean values
$var = "true"; // This is a string, not a boolean
$boolVar = (bool) $var; // Explicitly cast $var to a boolean

if ($boolVar) {
    echo "The boolean value is true";
} else {
    echo "The boolean value is false";
}
