What are the differences between intval and floor functions in php
This article mainly talks about "what are the differences between intval and floor functions in php". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what are the differences between intval and floor functions in php?"
Differences: 1, the intval () function is directly rounded off the decimal part, while the floor () function when the parameter is greater than 1, the decimal part is rounded, when the parameter is less than 1, the decimal part is removed and 1 is added on the basis of the integer. 2. The intval () function can be converted to binary, but not the floor function.

In php, both the intval and floor functions can be used for decimal rounding, so what's the difference between them? Let's take a look.
Floor () function
The floor () function rounds down to the nearest integer.
Syntax: floor (x)
Returns the next integer not greater than x, rounding off the fractional portion of x. The type returned by floor () is still float, because the range of float values is usually larger than integer.
Output:
0055-6-6
Intval () function
The intval () function is used to get the integer value of a variable.
Syntax:
Int intval (mixed var, int [base])
Return value: integer
Function type: PHP system function
Output:
forty-four
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.
