⟩ What are the different types of PHP variables?

PHP has a total of eight data types which we use to construct our variables −

☛ Integers − are whole numbers, without a decimal point, like 4195.

☛ Doubles − are floating-point numbers, like 3.14159 or 49.1.

☛ Booleans − have only two possible values either true or false.

☛ NULL − is a special type that only has one value: NULL.

☛ Strings − are sequences of characters, like 'PHP supports string operations.'

☛ Arrays − are named and indexed collections of other values.

☛ Objects − are instances of programmer-defined classes, which can package up both other kinds of values and functions that are specific to the class.

☛ Resources − are special variables that hold references to resources external to PHP (such as database connections).
