Does PHP support automatic typecasting for variables?

PHP does support automatic typecasting for variables, meaning that it will automatically convert variables from one data type to another as needed. This can be convenient but can also lead to unexpected behavior if not carefully managed. To ensure that typecasting is done correctly, it is important to be aware of the data types being used and to explicitly cast variables when necessary.

$number = "10"; // string
$sum = $number + 5; // PHP will automatically typecast $number to an integer and perform the addition
echo $sum; // Output: 15
