llHTTPRequest(), POST data and PHP

Hiya.

I'm trying to pass a string to a PHP script via llHTTPRequest(url, [HTTP_METHOD,"POST"], myString).

I've never used PHP before and thus have no idea how to get to the data in myString. Does anyone have any code snippets that illustrate how to get to these variables?

Thanks!

Well I don't know PHP but this may help.

If you POST the data string as the body, then the string will have to be read from the input stream of the POST request at the server side (i.e. it won't appear as http request parameters).

You could alternatively append a query string to the URL.

/esc

Well.. not good business sense, but in the interest of education:

Using the get method is much easier.

Simply append ?varname=value&varname2=value2...to infinity to your url to send data to that php script

Then, have that php script read data from:

$_GET['varname'];

...yes true, except urls have a limited length and so a GET query string may lead to corrupt data...

What I finally found that worked:

<?php
header("Content-type: text/plain; charset=UTF-8";

// taken from the comments on the llHTTPRequest wiki page
$p_data = implode('', file('php://input'));
$p_data = explode('&', $p_data);
foreach ($p_data as $p_val)
{
$d_parts = explode('=', $p_val);
$_POST[$d_parts[0]] = urldecode($d_parts[1]);
}

// to put results out to a file
$fp = fopen ( 'myOutput.txt', "w";
fwrite($fp, print_r($_POST, true));
fclose($fp);

// to assign values
$phpVar = $_POST["slVar"];

//dynamic values (where is $i is an integer)
$phpVarDyn = $_POST["slVar" . $i];

?>

My body in LSL was filled with key value pairs, identical to a url's query string. E.g.: key1=value1&key2=value2&key3=value3&keycount=3

Adding a keycount allowed me to loop through the keys using the 'dynamic values' syntax above.

I spent much too long putting all this information together so I hope it comes in handy for someone else.
