PHP prompt cannot be loaded or mcrypt is not found. PHP extension mbstring solution_PHP tutorial

The PHP extension mbstring was not found and you appear to be using a multibyte character set. phpMyAdmin without the mbstring extension does not split strings properly and may produce unexpected results.

Solution to mcrypt failure to load
Tips: The mcrypt (external link, English) extension cannot be loaded, please check your PHP configuration.
In the php.ini file in the C:WINDOWS directory,
the first ";" in ";extension=php_mcrypt.dll" is not removed
so the corresponding function cannot be used. The solution is to open php.ini file, find;extension=php_mcrypt.dll and change it to
extension=php_mcrypt.dll. Remove the previous; to make it effective
After modifying PHP.INI, restart the computer. .

If it still doesn’t work, the libmcrypt.dll file may be missing in the system’s system32 (usually C: WINDOWSsystem32) directory. The solution is to find libmcrypt.dll in the php directory, copy it to the C:WINDOWSsystem32 directory, and then restart IIS.

Unable to load mbstring solution:
win system :
