Method Detail



	
	
HTML_AJAX_JSON (Constructor)   [line 142]

	

    

    

		HTML_AJAX_JSON HTML_AJAX_JSON(
[int
$use = 0])
    

    


	
		constructs a new JSON instance




        
Parameters:

    

    

          

        int  
        $use  
        —
          
object behavior flags; combine with boolean-OR
possible values: 
  • SERVICES_JSON_LOOSE_TYPE:  loose typing.
                                   "{...}" syntax creates associative arrays
                                   instead of objects in decode().
  • SERVICES_JSON_SUPPRESS_ERRORS:  error suppression.
                                   Values which can't be encoded (e.g. resources)
                                   appear as NULL instead of throwing errors.
                                   By default, a deeply-nested resource will
                                   bubble up with an error, so all return values
                                   from encode() should be checked with isError()

decode   [line 484]

  • Return: number, boolean, string, array, or object                    corresponding to given JSON input string.                    See argument 1 to HTML_AJAX_JSON() above for object-output behavior.                    Note that decode() always returns strings                    in ASCII or UTF-8 format!
