Im sorry I am very new with arrays But I am interested in learning on this one. I think once I see the fix I will understand it, I know its something simple i just can not find what i am looking for.

 

[Mancent]

Anyone?

[trq]

The object you are getting back is NOT an array. It's json. See json_decode to turn it into an array.

[Mancent]

Any example: You can give,, the array has json, and I am converting it to xml, so the file product would be a xml, How can I do that? Could you show me?

[jcbones]

You need to encode the string before sending it to simpleXML.

 

The question mark (?) is what is causing it to barf.  I would suggest the work around.

//instead of:
$xml->addchild('element',$str);
//do
$xml->element = $str;

[Mancent]

Thank you guys you have been a really big help But however i have not yet had any luck getting it to work, more errors. so my mind just is not getting it yet!

[jcbones]

You need to change the amperstand (&) to &  You can do this with str_replace;

[Mancent]

{
		//$xml->addChild( $name, $value );
		$xml->$name = $value;
		}

 

Got it! That works perfect.

Your awesome  jcbones
