PHP: Types - ManualLearn about the type system and the data types of PHP, a popular general-purpose scripting language. The page covers NULL, booleans, integers, floating point numbers, strings, arrays, objects, enumerations, resources, callbacks, mixed, void, never, relative, class types, value types, iterables, type declarations, and type juggling.
Every single expression in PHP has one of the following built-in types depending on its value: null; bool; int; float (floating-point number) string; array; object; callable; resource; PHP is a dynamically typed language, which means that by default there is no need to specify the type of a variable, as this will be determined at runtime.
PHP does not break any rules with the values of true and false. The value false is not a constant for the number 0, it is a boolean value that indicates false. The value true is also not a constant for 1, it is a special boolean value that indicates true. It just happens to cast to integer 1 when you print it or use it in an expression, but it's not the same as a constant for the integer value ...
The key can either be an int or a string.The value can be of any type.. Additionally the following key casts will occur: . String s containing valid decimal int s, unless the number is preceded by a + sign, will be cast to the int type. E.g. the key "8" will actually be stored under 8.On the other hand "08" will not be cast, as it isn't a valid decimal integer.
