hi
The "X" in AJAX says that the data are XML Data.
To parse XML I use DOM.
It is also possible to validate the data using RelaxNG, DTD or XMLSchema
before processing.
A receiver in PHP looks like
<?php
//read the string ($HTTP_RAW_POST_DATA is by default
//not active -> use "php://input")
$content=file_get_contents("php://input");
//make a dom object
//many people know DOM already from programming javascript
$dom=domDocument::loadXML($content);
//validate with DTD,RelaxNG or XMLSchema
//http://at.php.net/manual/de/function.dom-domdocument-relaxngvalidate.php
if($dom->relaxNGValidate("test.rng")){
//than read the data you need
//for example if your XML looks like
//<person born="1935">
//<firstname>Dalei</firstname><lastname>Lama</lastname>
//</person>
$firstname=$dom->getElementsByTagName('firstname')->item(0);
$lastname=$dom->getElementsByTagName('lastname')->item(0);
$born=$dom->documentElement->getAttribute('born');
}else{
echo "data are not valid";
}
?>
If you don't like XML (AJAX) use JSON.
