Protype and communicating with external PHP file

Hi Guys
I have created this script to read URLs from a TXT file and the pass
them to an array .. this part is working good, but when I try to add
the second part of the script that will send each array element to a
PHP file to handle it and return the proper results, it doesnt work

Before I list the  script .. here is the content of Test3.txt

http://site.info/
http://site1.info/
http://site.com/


And here is an assumption how the PHP file blogs.php might look:

<?
   $keyword=$_REQUEST[''keyword''];
	echo $keyword;
?>

Here is my script below, any help is appreciated guys:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html;
charset=windows-1252">
<script src="prototype.js"></script>
<title>JS</title>
</head>
<body>
<SCRIPT LANGUAGE = JAVASCRIPT>
      var request = new ActiveXObject(''Msxml2.XMLHTTP'');
      request.open(''get'', ''Test3.txt'',
true);
      request.onreadystatechange = extractURLs;
      request.send();
       // document.write(responseText);
       function extractURLs() {
       // if (request.readyState == 4 && request.status == 200) {
           urlArray = request.responseText.split("\n")
           start_your_function(urlArray);
       // }
       document.write(urlArray.length);

      }
	    document.write(urlArray[5] + "<br />");
      var i=0 ;
      var dd= urlArray.length - 1;

       document.write(dd);
       document.write(i);
for (i=0;i<=dd;i++)
{
 var keyword=urlArray[i];
// When I add this part it is not working any more
                   var request2 = new
ActiveXObject(''Msxml2.XMLHTTP'');

     new Ajax.Request(''blogs.php?=''+keyword, true);

     Ajax.Responders.register(responder);

         document.write(i);

      document.write(keyword + "<br />"); */

               }

      </SCRIPT>

Protype and communicating with external PHP file

Hi Guys, I am writing this code to pull URLs form txt file and pass
them to an array .. (this part is working well)  but the second part
which is sending each array element to external PHP file to get some
results is not working for me.

The Text3.txt file is looking like this:

http://site.info/
http://site1.info/
http://site.com/

You can assume the blogs.php file will look like this :

<?
   $keyword=$_REQUEST[''keyword''];
	echo $keyword;
?>

Anybody can help me in that ? your help will be appreciated guys ..
here is my code

Re: Protype and communicating with external PHP file

Why are you making XHRs w/ the proprietary activeX syntax?  There is
your first problem, adopt Ajax.Request for any and all XHRs and half
your problems will be solved.

Also be careful when sending an array of data.  When you have
identically named pairs you can lose data.  You''ve got to use the
square bracket notation on your names, check out this demo i set up.
The responder justs print_r() the $_POST array..

http://positionabsolute.net/projects/javascript/name-pair-test.html


Lose data
var str = "name=matt&name=william&name=tobie&name=sam";

preserve data
var str =
"name[]=matt&name[]=william&name[]=tobie&name[]=sam";

There is a potential workaround.

Try this as your php script ...

<?php phpinfo(); ?>

Now run that like this ...

http://www.your-site.com/phpinfo.php?test=1&test=2

If you look through the config of your server, looking for test, you
will see that ...

$_SERVER[''QUERY_STRING''] =
''test=1&test=2''
$_SERVER[''REQUEST_URI''] =
''/phpinfo.php?test=1&test=2''

But, as correctly mentioned by Matt, both $_GET and $_REQUEST (and
$_POST if that was the submission method) will lose the data.

I don''t have a script to convert QUERY_STRING into an array that is
100% perfect (I''ve just realised that you can have multiple levels of
keys to support which makes it a little more awkward.

But, assuming the reason that you are using QUERY_STRING is because
you have not supplied keys (or used [] at all), then the following
script will help ...

<?php
// This function takes the servers QueryString and converts it to an array.
// It will deal with repeated names.
// An array is returned.
// NOTE: This function is specifically ignoring keys - if you have
supplied keys, then
//       you would not normally require this function.
function queryStringToArray()
	{
	// Default result is empty array.
	$a_Result = array();

	// Do we have anything to convert?
	if ('''' != $_SERVER[''QUERY_STRING''])
		{
		// Split the query string on a real &.
		$a_Parts = preg_split(''`&(?!amp;)`sim'',
$_SERVER[''QUERY_STRING'']);

		// Process each part into the result array.
		foreach($a_Parts as $s_Part)
			{
			$i_EqualPos = strpos($s_Part, ''='');
			// If no = or = is at the end of Part, then Part is Name and Value
is empty string.
			if ((0 == $i_EqualPos) || (strlen($s_Part) == 1 + $i_EqualPos))
				{
				// Remove any trailing 				$s_Name = rtrim($s_Part, ''='');
				$s_Value = '''';
				}
			else
				{
				// Split on the first 				$s_Name = substr($s_Part, 0, $i_EqualPos);
				$s_Value = substr($s_Part, 1 + $i_EqualPos);
				}

			// Does Name exist?
			if (array_key_exists($s_Name, $a_Result))
				{
				// Make the stored value an array and add the new value.
				$a_Result[$s_Name] = array($a_Result[$s_Name], $s_Value);
				}
			else
				{
				// Add the name/value to the results array.
				$a_Result[$s_Name] = $s_Value;
				}
			}
		}

	return $a_Result;
	}
?>

Usage would be ...

<?php
$a_Data = queryStringToArray();
?>

As an example, test.php?test=1&test=2&test=3

results in an array of ...

array ( ''test'' => array ( 0 => array ( 0 =>
''1'', 1 => ''2'', ), 1 =>
''3'', ), )
