gettype - Get the type of a variable

SYNOPSIS

       string gettype (mixed  $var)

DESCRIPTION

	Returns the type of the PHP variable $var. For type checking, use is_* functions.

PARAMETERS

	      o $var
		- The variable being type checked.

RETURN VALUES

	Possible values for the returned string are:

	      o "
		boolean"

	      o "
		integer"

	      o "
		double" (for historical reasons "double" is returned in case of a float, and not simply "float")

	      o "
		string"

	      o "
		array"

	      o "
		object"

	      o "
		resource"

EXAMPLES

       Example #1

	      gettype(3) example

	      <?php

	      $data = array(1, 1., NULL, new stdClass, 'foo');

	      foreach ($data as $value) {
		  echo gettype($value), "
";
	      }

	      ?>

	      The above example will output something similar to:

	      integer
	      double
	      NULL
	      object
	      string

EXAMPLES

       Example #1

	      Using get_class(3)

	      <?php

	      class foo {
		  function name()
		  {
		      echo "My name is " , get_class($this) , "
";
		  }
	      }

	      // create an object
	      $bar = new foo();

	      // external call
	      echo "Its name is " , get_class($bar) , "
";

	      // internal call
	      $bar->name();

	      ?>

	      The above example will output:

	      Its name is foo
	      My name is foo

       Example #2

	      Using get_class(3) in superclass

	      <?php

	      abstract class bar {
		  public function __construct()
		  {
		      var_dump(get_class($this));
		      var_dump(get_class());
		  }
	      }

	      class foo extends bar {
	      }

	      new foo;

	      ?>

	      string(3) "foo"
	      string(3) "bar"
