You can use mb_substr [1] with a UTF-8 encoding to get the single characters.

The problem is that if you set the post directly to the query it's available
to be an attach code in the field... (eg. DROP DATABASE;) it's called to
"SQL injection"...
what I mean on filtering:
always check the values in query eg.: $id = $_POST['id'];
if(is_numeric($id)){...}else{bad post}
and at other fields u can use eg. strstr() etc...

Hi,
Please advise if the following is possible and how can pass parameters
from the PHP to the Java application.
Thanks.
Here's my script draft:
<?PHP
...
....
$XML_toEnc = urlencode ($XML);
// The XML_toEnc
is a string and shall be urlencoded !
$EncXML = shell_exec(""/usr/bin/java/java -jar MyApp.jar -XML
<$XML_toEnc>); <<== ??? How can I pass parameters like a large string of
let say XML?
echo $EncXML; // back to the MObile Client
// Receiving client shall:
// urldecode the string
?>
