How does PHP handle data types differently compared to languages like C and C++?

PHP handles data types dynamically, meaning that variables do not need to be explicitly declared with a data type. This differs from languages like C and C++ where variables must be declared with a specific data type before they can be used. PHP automatically converts data types as needed, which can lead to unexpected behavior if not handled carefully.

// Example of PHP handling data types dynamically
$number = 10;
$string = "20";

$result = $number + $string; // $result will be 30, as PHP converts the string "20" to a number for the addition operation
echo $result;
