What role does the ";" character play in the PHP.ini file when configuring extensions?

The ";" character in the PHP.ini file is used to comment out lines of code. When configuring extensions, you can use the ";" character to disable or enable specific extensions by commenting or uncommenting the corresponding lines in the PHP.ini file.

; Enable the extension by removing the semicolon before the extension name
; extension=example_extension.so

; Disable the extension by adding a semicolon before the extension name
; ;extension=example_extension.so
