[SOLVED] Retrieve random string from page using cURL?

[slpctrl]

Hello, I need to use cURL to get a page, then have it decrypt a random encrypted string, it's just on the page. How might I do this? The encryption type is base64.

First you need to use a regular curl request to fetch the data of the page. Then you'll need to use some regex to keep only the part of the page you want, and then it's just about using base64_decode().

Getting the contents of the page shouldn't be a problem, a regular curl query.

Obtaining the part of the text you need is generally the tricky part- but that depends on how the HTML of that page looks like. If you are having problems with this part, post here (or in the regex board) how the HTML looks like (some kind of an example), and someone will help you find out how get the part you need.

The section of the page is seperated with the <div> tag like so:

 

 

<div class='main-body'>

<div style="text-align: center;">

<br /><br />

Random string: X3AtMGssLGB6KDZhY2lgXw==<br /><br />

</div>

 

How do I use that to retrieve the text? The encoded text is surrounded by text.

So you can use a simple regular expression to get the data:

 

<?php

preg_match_all("/Random string: ([a-zA-Z0-9=+\/]*)/", $html, $matches);
print_r($matches[1]);

?>

Alright, this is very close to what I need. Now, after some adjusting I've got the random string however it's in an array with only 1 element. How can I get that array to be a plain text variable with only the string?

<?php
$str = $matches[1];
echo $str;
?>

 

if that doesn't work can you post the results of

print_r($matches[1]);

The result is in $matches[1][0]
