V8Js::__construct - Construct a newV8Jsobject

SYNOPSIS

       public  V8Js::__construct  TRUE	([string   $object_name  =  "PHP"],  [array   $variables = array()], [array  $extensions = array()], [bool
       $report_uncaught_exceptions])

DESCRIPTION

	Constructs a new V8Js object.

PARAMETERS

	      o $object_name
		- The name of the object passed to Javascript.

	      o $variables
		- Map of PHP variables that will be available in Javascript. Must be an associative array in format array("name-for-js" =>  "name-
		of-php-variable"). Defaults to empty array.

	      o $extensions
		- List of extensions registered using V8Js.registerExtension(3) which should be available in the Javascript context of the created
		V8Js object.

	      Note

		      Extensions registered to be enabled automatically do not need to be listed in this array. Also if an extension has dependen-
		     cies, those dependencies can be omitted as well. Defaults to empty array.

	      o $report_uncaught_exceptions
		-  Controls whether uncaught Javascript exceptions are reported immediately or not. Defaults to TRUE. If set to FALSE the uncaught
		exception can be accessed using V8Js.getPendingException(3).

RETURN VALUES

	Returns a new V8Js context object.

ARRAY_KEY_EXISTS(3)							 1						       ARRAY_KEY_EXISTS(3)

array_key_exists - Checks if the given key or index exists in the array

SYNOPSIS

       bool array_key_exists (mixed  $key, array  $array)

DESCRIPTION

       array_key_exists(3) returns TRUE if the given $key is set in the array. $key can be any value possible for an array index.

PARAMETERS

	      o $key
		- Value to check.

	      o $array
		- An array with keys to check.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      array_key_exists(3) example

	      <?php
	      $search_array = array('first' => 1, 'second' => 4);
	      if (array_key_exists('first', $search_array)) {
		  echo "The 'first' element is in the array";
	      }
	      ?>

       Example #2

	      array_key_exists(3) vs isset(3)

	      isset(3) does not return TRUE for array keys that correspond to a NULL value, while array_key_exists(3) does.

	      <?php
	      $search_array = array('first' => null, 'second' => 4);

	      // returns false
	      isset($search_array['first']);

	      // returns true
	      array_key_exists('first', $search_array);
	      ?>

NOTES

       Note

	       For backward compatibility, the following deprecated alias may be used: key_exists(3)

       Note

	       For  backward compatibility reasons, array_key_exists(3) will also return TRUE if $key is a property defined within an object given
	      as $array. This behaviour should not be relied upon, and care should be taken to ensure that $array is an array.

	       To check whether a property exists in an object, use property_exists(3).
