PHP and FLEX communication

Communication between PHP and Flash using POST method of HTTPService service:-

Here I have created Flex project which passes two variables to PHP and get the sum back from PHP and displays the same in Flex. You need to send the variables in “name” “value” to PHP page as shown in code, same name value pair can be passed as Sum_HttpServ.send({num1:’3′,num2:’6′});

Below is the code written in Flex application:-

<?xml version=”1.0″ encoding=”utf-8″?>
<mx:Application xmlns:mx=”; layout=”absolute” creationComplete=”fnCreationComplete()”>
                <mx:HTTPService id=”Sum_HttpServ” url=”http://yourDomain/someFolder/GetSum.php&#8221; result=”fnDiplayResult(event)” fault=”fnHandleFault(event)”/>
                                import mx.controls.Alert;                               

                                private function fnCreationComplete():void{
                                                var Obj:Object=new Object();
                                private function fnHandleFault(event:FaultEvent):void{
                                     "Error ID="+event.fault.errorID+"  faultString="+event.fault.faultString);

                                private function fnDiplayResult(event:ResultEvent):void{

Below is the code written in the PHP “http://yourDomain/someFolder/GetSum.php&#8221; page which is placed on remote machine in virtual directory

print ($Number1+$Number2);

To use GET method, you need to change Sum_HttpServ.method=”POST”; in flex project and use $_GET[‘num1'] and $_GET[‘num2'] in PHP page.

Getting Multiple parameters from PHP:-
To return the multiple parameters from PHP you can return the variables separated by ampersand (&) if you are using flashvars as resultFormat. There are fore more formats namely “text”, “array”, “xml”, “e4x” you can use anyone as per your need but depending on that you will have to format your response object in PHP.  Here I am using flashvars as result format.

Below is the PHP code that returns addition & multiplication of variable.

print “Addition=$Addition&Multiplication=$Multiplication”;

And now you are ready to send the variables from PHP. Now in flex application, your fnDiplayResult() function will change to

private function fnDiplayResult(event:ResultEvent):void{
                      “Addition = “+event.result.Addition);
                      “Multiplication = “+event.result.Multiplication);

And add line Sum_HttpServ.resultFormat=”flashvars”; in fnCreationComplete() function before you send the parameters to PHP.

    its good Nitin.can u tell me how data from database display in combobox in flex through php.

  6. Nitin Gore says:

    Hi Shital, first get the data from database in any format you like, then you need to convert it to Arraycollection of string objects. And then you can use this arraycollection as a data provider for the combo box.
