PHP gettype() Function

The gettype() function returns a string representing the type of the variable. This is useful when you are unsure what data you received (e.g., from a database or a form) and want to verify its type before further processing.

EXAMPLE

$text = "Hello Borut";
$integerNumber = 13;
$decimalNumber = 13.45;
$myArray = ["a", "b", "c"];
$emptyValue = NULL;
$isProgrammer = true;

echo "Type for \"$text\" is: " . gettype($text) . "\n";
echo "Type for number $integerNumber is: " . gettype($integerNumber) . "\n";
echo "Type for decimal $decimalNumber is: " . gettype($decimalNumber) . "\n";
echo "Type for array [\"a\", \"b\", \"c\"] is: " . gettype($myArray) . "\n";
echo "Type for NULL is: " . gettype($emptyValue) . "\n";
echo "Type for true is: " . gettype($isProgrammer) . "\n";

// Example of checking type in a condition
if (gettype($integerNumber) === "integer") {
    echo "\nThe variable is an integer, we can proceed with calculations.";
}
