Composer kurarken "The PHP exe did not run correctly" hatası

The PHP exe file you specified did not run correctly:
D:\xampp\php\php.exe

The php.ini used by your command-line PHP is: D:\xampp\php\php.ini

A setting in your php.ini could be causing the problem: Either the 'extension_dir' value is incorrect or a dll does not exist.

Program Output:
PHP Warning: PHP Startup: Unable to load dynamic library 'php_gd2.dll' (tried: D:\xampp\php\ext\php_gd2.dll (Belirtilen modül bulunamadı), D:\xampp\php\ext\php_php_gd2.dll.dll (Belirtilen modül bulunamadı))
