The problem is that the file encrypted cryptmessage.txt is not read to the end, because the number of push_backs when reading message.txt countpb1 != countpb2 94!=34 from the cryptmessage.txt file Help is urgently needed, do not be afraid that there is a fierce crypt, the problem is reading files, because ct1!=ct2 i.e. ct1 = 754 ,a ct2=418 and should be equal to one another because the reading algorithms are the same

Answer 1

Perhaps you are converting characters.
Try "rb" mode for reading, "wb" for writing.

Answer 2

preg_match('/href=\"(.*?)\"/', $var)
