php method to convert floating point numbers to integers :

Built-in function intval() in php is used to get the integer value of a variable. Returns the integer value of var on success and 0 on failure. An empty array returns 0, a non-empty array returns 1.

intval()The function returns the integer value of the variable var by using the specified base conversion (the default is decimal). intval() cannot be used with object, otherwise an E_NOTICE error will be generated and 1 will be returned.

Syntax:

int intval ( mixed $var [, int $base = 10 ] )

Parameter description:

• $var: The quantity value to be converted to integer.

• #$base: The base used for conversion.

If base is 0, the base used is determined by detecting the format of var: if the string includes the prefix of "0x" (or "0X"), use hexadecimal (hex); otherwise, if the string starts with "0", octal will be used; otherwise, decimal will be used.
