Value 0 and 1 is equal to false and true in php

Question

some time we use 0 value or 1 value for php, instead of 0 and 1 value, can we use True/False method in php.

Answer 1

A boolean TRUE value is converted to the string "1". Boolean FALSE is converted to "" (the empty string). This allows conversion back and forth between boolean and string values.

Answer 2

We converting the in boolean datatype in FALSE:

• the boolean FALSE itself the integer 0 (zero)
• the special type NULL (including unset variables)
• an object with zero member variables (PHP 4 only) string "0"
• SimpleXML objects created from empty tags
• the empty string,and the
• the float 0.0 (zero)
• an array with zero elements

Every other value is considered TRUE.
