The is_float() function in PHP checks if a variable is an integer.

This statement is false. The is_float() function in PHP checks if a variable is a float, not an integer. It returns true if the variable is a float (a number with a decimal point or an exponential form) and false otherwise. To check if a variable is an integer, you can use the is_int() function.
