    JsHttpRequest::JsHttpRequest
    


    
JsHttpRequest(

$enc );

    




    Описание
    

    Constructor.
    

    Create new JsHttpRequest backend object and attach it  to script output buffer. As a result - script will always return  correct JavaScript code, even in case of fatal errors.
    QUERY_STRING is in form of: PHPSESSID=<sid>&a=aaa&b=bbb&JsHttpRequest=<id>-<loader>  WHERE <id> is a request ID, <loader> is a loader name, <sid> - a session ID (if present),  PHPSESSID - session parameter name (by default = "PHPSESSID").
    If an object is created WITHOUT an active AJAX query, it is simply marked as  non-active. Use statuc method isActive() to check.

    Описание
    

    string getJsCode()
    

    Return JavaScript part of the library.
    
		
    [ Наверх ]
    

    



    JsHttpRequest::isActive
    


    
isActive(
 );

    




    Описание
    

    Static function.
    

    Returns true if JsHttpRequest output processor is currently active.

    JsHttpRequest::php2js
    


    
php2js(
[mixed
$a = false] );

    




    Описание
    

    Convert a PHP scalar, array or hash to JS scalar/array/hash. This function is  an analog of json_encode(), but it can work with a non-UTF8 input and does not  analyze the passed data. Output format must be fully JSON compatible.
    
		
    Принимаемые параметры
    
			
    $a
    
		
    Any structure to convert to JS.

    JsHttpRequest::quoteInput
    


    
quoteInput(

$s );

    




    Описание
    

    string quoteInput(string $input)
    

    Quote a string according to the input decoding mode.  If entities are used (see setEncoding()), no '&' character is quoted,  only '"', '>' and '<' (we presume that '&' is already quoted by  an input reader function).
    Use this function INSTEAD of htmlspecialchars() for $_GET data  in your scripts.

    Описание
    

    void setEncoding(string $encoding)
    

    Set an active script encoding & correct QUERY_STRING according to it.  Examples:    "windows-1251"          - set plain encoding (non-windows characters,                              e.g. hieroglyphs, are totally ignored)    "windows-1251 entities" - set windows encoding, BUT additionally replace:                              "&"         ->  "&amp;"                              hieroglyph  ->  &#XXXX; entity

    Internal function, used in array_walk_recursive() before json_encode() call.
