I have a Java string array lets say something like this:

String [] distance = {"40","43","32","313","3123"};

I sent this array as a POST message to the server where a php file reads this array.

nameValuePairs.add(new BasicNameValuePair("distance",distance); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); httpclient.execute(httppost);

This entire array will be read in this variable: $_POST['distance']

I am unable to access an element in this array using $_POST['distance[0]'].

How can i access only one specified element from this variable

If I put your sample String [] distance = {40,43,32,313,3123}; in a .java source file I get the error Type mismatch: cannot convert from int to String — also, Java and PHP are both generally server-side languages. If you're sending this array as a POST could you mean javascript rather than java? – Stephen P Jul 8 '14 at 21:22
    
On the other hand, String [] distance = {40,43,32,313,3123}; isn't valid javascript syntax either. – Stephen P Jul 8 '14 at 21:25
    
@StephenP You are right. I have edited my java code. – user3760741 Jul 8 '14 at 21:26

You should read in the array element in PHP as:

$distance = explode(',', $_POST['distance']);
echo $distance[0];

You have plenty of options.

  1. Encode the data as JSON on the Java side and decode the string on the PHP side.
  2. Post the data as a string with Java that is detected as array in PHP: distance[]=40&distance[]=43&distance[]=32&...
  3. Work on the actual string you get and decode the native form created by Java, i.e. comma separated list of values.

I am not sure, but if you send string via post, you can try to replace data until you get something like this 40,43,32,313,3123

and after you can use php function explode.
