How to crack PHP shield encryption and decryption

After cracking phpjm.net's encryption, today we have cracked the bird "PHP shield! This bird encryption is basically the same as phpjm.net's practice. It is nothing more than a little bit of skill. He also made a jump in the encryption code and jumped to their website, do not touch the bottom line that we tolerate, fuck! He copied other people's encryption methods and shouted at him! Now we have also implemented a batch decryption program to publish some code. If you don't miss them for the time being, you can see them all in the future! Qq contact: 267014855

// Decrypt PHP shield $ file = 'Code. php'; $ fp = fopen ($ file, 'R'); $ str = fread ($ fp, filesize ($ file); fclose ($ fp ); $ code = strdecode ($ str); // The following is not published. It is not a problem to continue cracking here, php will be able to break through // a series of regular expression searches and function calls (the function is the following )//..... $ str = explode
