to distinguish multiple echo from php page
Jun 27^th, 2008, 10:48am

hi there
i am calling a php page using processing and am echoing lots of different contents on that page.
i want to receive all that content in processing but processing is receiving all the echo as a single element of the array

can anyone suggest how to differentiate the different contetnts being echoed by php page?
Also since the echoed matter is actually text from web so breaking the string based on delimiters may not be very good idea in this case.

The processing code:

String [] position;
int num,num1;
void setup()
{
background(255,255,255);
String url = "http://turing.lecolededesign.com:16080/~rshukla/gui_feed.php";
position = loadStrings(url);
//num= int(position[0]);
//println(num);
println(position);
}

void draw()
{

}

the php page
http://turing.lecolededesign.com:16080/~rshukla/gui_feed.php

the simplest solution is to modify the php script so each string echoed is escaped with "\n":

Code:

<?php
echo "line a\n";
echo "line b\n";
?>

then, you'll get your array of strings just using loadStrings() as you did.

otherwise, if you can't modify the php script, try spliting the string you got with the "http://" token :

Code:

String[] links = split(position[0], "http://");
for (int i = 1; i < links.length; i++)
  println("http://" + links[i]);

will return the list of the webpages.
