Spring Brother Technology blog to talk about PHP source encryption that something

Today Spring Brother Technology blog to everyone about the source of encryption of those things. Encryption is a hindrance to progress, ASP. NET is because they are compiled post, resulting in a few excellent source code.

PHP Source comparison is commonly used Zend Company's Zendguard and Ioncube Company's Ioncube PHP Encode. Neither of these encryption can be run independently. The Zendoptimizer and ioncube PHP accelerator PHP engine will be able to decode the operation normally. If you do not want to encrypt under a third-party engine, you can use the following method: see Code

function Encode_file_contents ($filename) {

$type =strtolower (substr (STRRCHR ($filename, '. '), 1));

if (' php ' = = $type && is_file ($filename) && is_writable ($filename)) {//If it is a PHP file and can be written with compression encoding

$contents = file_get_contents ($filename); Determine if the file has been encoded

$contents = Php_strip_whitespace ($filename);

Remove PHP header and tail markings

$headerPos = Strpos ($contents, ' <?php ');

$footerPos = Strrpos ($contents, '?> ');

$contents = substr ($contents, $headerPos + 5, $footerPos-$headerPos);

$encode = Base64_encode (Gzdeflate ($contents)); Start coding

$encode = ' <?php '. " \ n Eval (gzinflate (Base64_decode ("." "). $encode. "'". "))); N\n?> ";

Return file_put_contents ($filename, $encode);

}

return false;

}

Run the encrypted code after eval (gzinflate (Base64_decode (' encrypted string '));

As follows

This is the source code.

The post-encryption prototype is like this.

It's complicated after that.

After that, it's like this.

Key points function: eval (), Base64_encode (), Base64_decode (), Gzinflate (), Gzdeflate ()

It can also be used in combination with other encoding and decoding functions.
