Using output from other sites?

[Tandem]

The site below contains just some plain text.

https://daopay.com/svc/numgen?appcode=41970&orderno=yes&format=hash&country=GB&price=1.0

I want to be able to take the digits next to "number=" and next to "orderno=" and be able to use them in a script.

As of now i have not even attempted this as i really don't know where to start, and would be grateful for any help, thanks.

You can use [url=http://www.php.net/manual/en/function.file-get-contents.php]file_get_contents()[/url] with the URL (depending on your server setup) to put the entire contents of that file in a string, then use a regular expression to get the two values.

I've tried the following code and it appears to work fine.

[code]<?php

$string = file_get_contents('https://daopay.com/svc/numgen?appcode=41970&orderno=yes&format=hash&country=GB&price=1.0');

// strip out the new lines
$string = preg_replace("/\n/", "", $string);

// match the values after the string 'number' and 'orderno'
preg_match("/number=(\d+).*orderno=(\d+)/", $string, $matches);

foreach ($matches as $k => $v){
  if ($k > 0){
      echo "Key: $k - Value: $v<br>\n";
  }
}

// of if you don't want to loop
$number = $matches[1];
$orderno = $matches[2];

echo "$number<br>\n$orderno";

?>[/code]

Thanks for your responses. I tried the code out, and i get the following error:

Warning: file_get_contents(https://daopay.com/svc/numgen?appcode=41970&orderno=yes&format=hash&country=GB&price=1.0) [function.file-get-contents]: failed to open stream: Invalid argument in C:\...... on line 2

Can't figure out why myself as i don't really understand file_get_contents() very well.

[HuggieBear]

Can you post the code you have then.

It's the exact code above, totally on it's own.

[HuggieBear]

OK, what version of PHP are you running?

Regards
Huggie

[Tandem]

it's version 4.3.11

[code]<?php
$lines = file("https://daopay.com/svc/numgen?appcode=41970&orderno=yes&format=hash&country=GB&price=1.0");
$data = array();
foreach($lines as $line)
{
list($key,$value) = explode('=',$line);
$data[$key] = $value;
}
?>[/code]

Will read the data into an array.

Simpler and it worked when I tested it.

Make a file that contains:
[code]<?php
phpinfo();
?>[/code]

Upload it and run it. Then check if the directive "allow_url_fopen" is set to on or off.

Orio.

Daniel, file() is identical to file_get_contents, the only subtle difference is it returns it into a string instead of an array, it's likely to cause the exact same error.

Tandem, create a file like this:

phpinfo.php
[code=php:0]<?php
  phpinfo();
?>[/code]


Open it in your browser and scroll down to PHP Core.  Look for the value allow_url_fopen and see if it's switched 'on'

Oh wait, they weren't working on my local test server, but when i uploaded them to my real host they worked fine.

I'll do the allow_url_fopen thing for my test server. Thanks alot for the help.

Yeah, but it's simpler and more more effecient to run through a loop and explode the lines instead of using regular expressions.

That I won't deny  :)  but that still wouldn't have fixed his immediate problem.

On my test server where the file() and file_get_contents function won't work, the allow_url_fopen is set to On.

Should that be set to off or...?

[Orio]

If it's on they [i]should[/i] work. Unless something else is blocking it...

Is this the FULL error you get?

Orio.

[HuggieBear]

It should be set to 'on' to allow the functionality you're after, but I think your local test server needs to be set-up to be publically available to use the features properly, in a DMZ otherwise you'll have firewall and all sorts to overcome.

I'd be willing to bet it's network related and not php related.

I am not sure if this could have any effect on it, but is safe mode on?
