php error. Module issue? (MacOS)?

Question

PHP

Tried to install gd module for support in png. I installed it according to some guide and after the ln -sf command, everything stopped working at all. Now php gives an error:
"PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20160303/php_gd2.dll' - dlopen(/usr/lib/php/extensions /no-debug-non-zts-20160303/php_gd2.dll, 0x0009): closured error in Unknown on line 0"
