The PHP extension mbstring was not found, and you now appear to be using a multi-byte character set. phpMyAdmin without the mbstring extension does not properly split the string and can produce unexpected results.

Therefore, the corresponding function cannot be used. The solution is to open the php.ini file and find; extension = php_mcrypt dll change
extension= php_mcrypt.dll; Into law
Restart the computer after you have modified PHP.INI.

If this is not possible, the libmcrypt.dll file can be missing from the system's system32 (1: C:\WINDOWS\system32) directory. The solution is to find libmcrypt.dll in the php directory, copy it to C:\WINDOWS\system32, and restart IIS.
