This article focuses on "how to convert floating-point to int in php". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to convert floating point to int in php.

The method of changing floating point type to int type in php: 1, use intval () function, syntax "intval (floating point data)"; 2, use settype () function, syntax "settype (floating point data, 'integer')".

Operating environment of this tutorial: windows7 system, PHP7.1 version, DELL G3 computer

The way to convert floating-point to int in php:

Method 1: use the intval () function

The intval () function is used to get the integer value of a variable.

The intval () function returns the integer value of the variable var by using the specified binary base conversion (the default is decimal). Intval () cannot be used for 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 numerical value to be converted to integer.

$base: the base used for conversion.

If base is 0, determine which binary to use by examining the format of the var:

Use hexadecimal (hex) if the string includes the prefix of "0x" (or "0X"); otherwise

Use octal (octal) if the string starts with "0"; otherwise

Decimal (decimal) will be used.

Return value: the integer value of var is returned on success and 0 on failure. Empty array returns 0, and non-empty array returns 1.

Example: convert a floating point to an int

Method 2: use the settype () function

The settype () function is used to set the type of variable.

The types that can be set are:

"boolean" (or "bool", starting with PHP 4.2.0)

"integer" (or "int", starting with PHP 4.2.0)

"float" (available only after PHP 4.2.0, "double" used in older versions is now disabled)

"string"

"array"

"object"

"null" (since PHP 4.2.0)

Note: the settype () function changes the type of the variable itself.
