Integer Data Type:

 

In PHP integer is single-value type. Integers are whole numbers. Its range varies according to your platform. But you can use any number from -2,147,483,648 to +2,147,483,647. Integer can be written in decimal, octal and hexadecimal. In decimal we can represent integer without zero.

 

For example:

 

1998 (Decimal)

 

 

In octal integer can be represented with a leading 0 and a sequence of digits from 0 to 7.

 

For example:

 

0755 (Octal)

 

 

In hexadecimal integer can be represented with 0-9 and alphabets A-F. 


For example:

 

0xFF(hexadecimal)

 

 

In php we just assign a value to a variable and on the basis of that value data type is confirmed.

$a = -123;                  //as  a negative number

$a = 0123;               //as a octal number (equivalent to 83 decimal)

$a = 0x12;             //as a hexadecimal number (equivalent to 18 decimal)

?>
