在文件中查找密码

I have a piece of php code that upon a page load request finds a corresponding file which contains information about the page including the password.

The syntax in the file is as follows:

Pagename: 
PageInfo:
Password: SecretPassword 

How would I get around finding the password following the Password:?

My PHP code looks like this:

$filepath = absolute_url("page/info.php");  
$infoFile = fopen("$filepath", "r");
$contents = stream_get_contents($infoFile);

Seems a very strange way to store the data. Assuming this can't be helped though, you could RegEx this with something like:

$matches = array();
preg_match('/Password:\s(.*)$/', $contents, $matches);
//                     ^ Assuming there's only ever 1 space

echo $matches[1] will print SecretPassword
