setting up a php web server

mrobertson · 06-02-2005, 07:40 AM

I am currently working on a creating a php server to recive values from a vb6 client. It has been suggested to me that I set up a web server......request the url from my vb6 client......pass the values to a php script.....and parse the values out. I am curious what the steps are to create this web server and declare the url that these values will be passed to. I am looking for specific examples or source code that may help me. I am brand new to php coding and this type of programming but am willing to learn. any help would be greatly appreciate. Please include specific code if at all possible.

To pass a variable in a url you send it as :
http://myhost.net/script.php?MyGreatVariable=AnyValue

(Do not forget to encode it if it contains special chars like space)
And the script.php that get the value :

PHP Code:



<?php 
//see if the variable is in $_GET array 
if (isset($_GET['MyGreatVariable']) ) { 
    // print the value 
    echo $_GET['MyGreatVariable']; 
} 
?>

look at www.php.net, very usefull resources for PHP and
a valuable search in php functions feature

How do you set up that url and where do you set it up at? Is it set up in vb6 or php. Also how and where do you code the php on a knoppix linux system. I tried to code in the text editor and it is giving me an error on the first line (ie. <?) saying no such file or directory exists. My string that is passed is four variables separated by commas (ex. 1234, 12.44, 56.99, 0.876). Could you explain more about the url in detail as to how exactly to set it up and where also what my host is.........Mygreat variable would be and any value would be.

Well, I know nothing about vb6, I never programmed in windows...
From the questions you are asking, may I suggest you to read
the basic of php here ?

I am also having a problem with my php coding I have the following code wrote:

<?
$vars = explode(", ", urldecode($_SERVER["QUERY_STRING"]));
foreach ($vars as $var){
print $var."<br>";
}
?>

I keep getting the same errors:

./PHPServer2.php: line 1: ? No such file or directory
./PHPServer2.php: line 2: Syntax error near unexpected token (
./PHPServer2.php: line 2: '$vars = explode(", ", urldecode($_SERVER["QUERY_STRING"]));

What would be causing this? I am trying to run it from the command line. I even tried to add

#!/usr/bin/php at the beginning of the program but it still didnt work. Any ideas on what is going on here?
