How to use Type Casting In PHP
One basic way to convert an integer to a double is by using type casting. PHP allows you to explicitly cast a variable to a different type using the (float) or (double) cast.
PHP
<?php // Original integer value $intValue = 42; // Convert to double using type casting $doubleValue = (float)$intValue; // Display the result echo "Integer: $intValue, Double: $doubleValue"; ?> |
Output
Integer: 42, Double: 42
