                                    intval

   (PHP 3, PHP 4 )
   intval -- Get integer value of a variable

Description

   int intval ( mixed var [, int base])

   Returns the integer value of var, using the specified base for the
   conversion (the default is base 10).

   var may be any scalar type. You cannot use intval() on arrays or
   objects.

     Note: The base argument for intval() has no effect unless the var
     argument is a string.

   See also floatval(), strval(), settype() and Type juggling.
