Description:
------------
I am encrypting two php scripts and saving redistributable keys to ".blenc_keys" file. When running the first script (blenc_myscript_encoded.php) everything works fine, but when running the second script (blenc_myscript2_encoded.php) I get warning:

    Warning: blenc_compile: Validation of script 'C:\phpdesktop\phpdesktop-chrome\www\blenc_myscript2_encoded.php' failed. 
    MD5_FILE: c269d23aa66d05474d7b408484c74c1d MD5_CALC: bbf95ab01978895e216cc1d6ed4ccaea in Unknown on line 0

The second script executes fine after that warning is shown.

The blenc_encode.php example encrypts php script and saves redistributable key. There is also blenc_encode2.php that does the same but for blenc_myscript2.php / blenc_myscript2_encoded.php.

<?php

$source_code = file_get_contents("blenc_myscript.php");
$source_code = preg_replace('#^<'.'\?php\s+#', '', $source_code);
$source_code = preg_replace('#\s+\?>\s*$#', '', $source_code);
$redist_key = blenc_encrypt($source_code, "blenc_myscript_encoded.php");
$key_file = ini_get('blenc.key_file');
file_put_contents($key_file, $redist_key."\n", FILE_APPEND);
?>

On blenc_encrypt() manual page (http://php.net/manual/en/function.blenc-encrypt.php) there is an error in Example #1. Redistributable keys are saved on the same line, but they should be seperated by new line character. This line:

    file_put_contents($key_file, $redistributable_key, FILE_APPEND);

Should be changed to:

    file_put_contents($key_file, $redistributable_key."\n", FILE_APPEND);

People are getting into troubles because of that when script is run multiple times. Blenc key file is getting corrupted and results in a fatal error:

    Fatal error: blenc_compile: Validation of script 'encrypt.php' failed,
    cannot execute. in C:\xampp\htdocs\PHPEncode\encode.php on line 14

I'm suspending the reports for BLENC as it doesn't seem to have stalled (looking at both repositories I could find on git.php.net and github) and it does not seem compatible with any currently supported version of PHP either. Please unsuspend in case someone takes over this extension
