    PHP supports the following types:

   
      array
     
      floating-point numbers
     
      integer
     
      object
     
      string
     
  
   The type of a variable is usually not set by the programmer;
   rather, it is decided at runtime by PHP depending on the context in
   which that variable is used.
  
   If you would like to force a variable to be converted to a certain
   type, you may either cast the variable or
   use the settype() function on it.
  
   Note that a variable may behave in different manners in certain
   situations, depending on what type it is at the time. For more
   information, see the section on Type Juggling.
  Integers
    Integers can be specified using any of the following syntaxes:
      1 
  2 $a = 1234; # decimal number
  3 $a = -123; # a negative number
  4 $a = 0123; # octal number (equivalent to 83 decimal)
  5 $a = 0x12; # hexadecimal number (equivalent to 18 decimal)
