PHP intval () function ____ function

Definition and Usage:

Gets the integer value of the variable, allowing it to be returned using a specific system. Default 10 system
Note: If the argument is an integer, no processing is done.

Grammar:

Intval (Var, base)

Parameter list:

Parameters	Description
Var	Have to. Can be any scalar type. Intval () cannot be used in arrays or objects (classes). I have to mention here. Scalar types contain four kinds: Boolean (Boolean) integer (integer) float (floating-point type, also called Double) string (string)
Base	Optional. Transform the system used, default 10 if base is 0, determine the use of the system by detecting the format of the Var argument: If the string includes a prefix of "0x" (or "0X"), use 16 if the string starts with "0" and uses 8 to other uses 10

For example:

Echo intval ("0x1a", 0), "\ n"; Use the 16-in system. Results "Intval" 
Echo ("057", 0), "\ n";//using 8. Results "10" 
Echo intval ("a"), "\ n"; Results
Echo intval ("0"), "\ n";
