Php Data-type Examples decbinbindecConverting from a boolean to a string will produce a 1 if the boolean is set to true, or an empty string if false. PHP provides a couple of constants especially for use as BooleansBoolean values Boolean type constantCasting a Variable Casting the return value Change the data type Changing Type by Casting Converting to in parentheses before our variable name Maintaining the integrity of the data and outputting the end result. Force to change the data type by adding (int), (integer), (float), (double), or (real) in front of the variable When the first expression is a string, the type of the variable will depend on the second expression. convert to float Typecasting Type conversionType conversionType conversionType conversions Convert String to Date Predefined Characters and Classes String char count Validating a number with ctype_digit() PHP Data Types gettype() and settype() Data Types Returns true if $a is an array Returns true if $a is a floating-point number Returns true if $a is an integer Create Object and check its type Create Object and get its type Returns true if $a is a string is_numeric in action bool empty ( mixed var ) returns true if its parameter has a false value Addition of two floating-point variables compared to a variable can lead to an unexpected result. Addition of two floating-point variables compared to a variable with the expected value result can lead to an unexpected result. Compare floating-point values,avoid the == operator and use the , , =, and =.
