Type Functions

Example

use TypedPHP\Functions\TypeFunctions;

TypeFunctions\getType(1.5); // number

TypeFunctions\isBoolean(false);   // true
TypeFunctions\isBoolean("false"); // false

Functions:

• isNumber(mixed $variable) → bool
• isBoolean(mixed $variable) → bool
• isNull(mixed $variable) → bool
• isObject(mixed $variable) → bool
• isFunction(mixed $variable) → bool
• isExpression(mixed $variable) → bool
• isString(mixed $variable) → bool
• isResource(mixed $variable) → bool
• getType(mixed $variable) → string

Caveats:

• isExpression will return false if isString returns true.
• isFunction will return false if isObject returns true.
• getType will return unknown if the argument is not matched by any of the is* functions.
