[RESOLVED] Extracting values from long string

[nicky77]

Hi guys, i think this should be pretty straightforward but I'm not too sure how to do it. I need to extract certain values from an encoded cookie, such as username and password etc. When i decode the cookie, i am left with a string such as the following:

s:5:"email";s:29:"email@yahoo.com";s:8:"username";s:8:"theuser1";s:8:"password";s:50:"c4b16518512c64eba2ca9752ce50f690f9e3d105cbadd47066";

If I want to extract the email, username and password values, what is the best way to split up the string?

Thanks in advance for any help!

explode might be good for this


$str = 's:5:"email";s:29:"email@yahoo.com";s:8:"username";s:8:"theuser1";s:8:"password";s:50:"c4b16518512c64 eba2ca9752ce50f690f9e3d105cbadd47066';

$parts = explode('";s:8:"', $str);

foreach($parts as $k => $v)
{
echo "Key: " . $k . " Value: " . $v . "<br />";
}


you might have to refine it to get the values you want but it should work

That 'encoded cookie' looks serialized to me.. but I'm not 100% positive.

Checkout unserialize() (http://php.net/unserialize)

Cheers for the replies. Legendx, you're right it looks like a serialized object - the only thing is that when i try to unserialize it i get a blank result. The actual decoded output is much longer than the one i originally posted, here it is:

session_id|s:32:"cfaeda9cfb76b9571c0ea70f0351b69a";total_hits|i:34;_kf_flash_|a:0:{}user_agent|s:90:"Mozilla/5.0 (Windows; U; Windows NT 6.0; en-GB; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1";ip_address|s:12:"27.236.81.31";last_activity|i:1220370914;auth_user|O:10:"User_Model":6:{s:14:"�*�object_name";s:4:"user";s:9:"�*�object";a:6:{s:2:"id";i:12;s:5:"email";s:29:"email@yahoo.com";s:8:"username";s:8:"theuser1";s:8:"password";s:50:"c4b16518512c64 eba2ca9752ce50f690f9e3d105cbadd47066";s:6:"logins";i:23;s:10:"last_login";i:1220365480;}s:10:"�*�changed";a:0:{}s:9:"�*�loaded";b:1;s:8:"�*�saved";b:1;s:10:"�*�sorting";a:1:{s:2:"id";s:3:"asc";}}

Sorted - used session_decode() instead of unserialize()

This will work for your original string.

$string='s:5:"email";s:29:"email@yahoo.com";s:8:"username";s:8:"theuser1";s:8:"password";s:50:"c4b16518512c64 eba2ca9752ce50f690f9e3d105cbadd47066";';
$pattern='/"[a-z A_Z @ \. 0-9]*"/';
preg_match_all($pattern,$string,$parts);

//print_r($parts);
foreach($parts as $v0){
foreach($v0 as $k => $v){
if($k=='1') $email=$v;
if($k=='3') $username=$v;
if($k=='5') $password=$v;
}
}
echo $email.'<br>';
echo $username.'<br>';
echo $password.'<br>';

Will the cookie info vary? As long as it label/value you can combine the odd/even keys then examine the keys for the one you want.

$parts = explode('";s:8:"', $str);
The s:x value is not the same Phil so that wouldn't work.
