What are the potential pitfalls of incorrect path settings for PHP extensions in the php.ini file?

Incorrect path settings for PHP extensions in the php.ini file can lead to errors such as "extension not found" or "unable to load dynamic library". To solve this issue, you need to ensure that the extension_dir path in php.ini is correctly set to the directory where your PHP extensions are located. Additionally, make sure that the extension file itself is in the specified directory.

; Path to the directory where PHP extensions are located
extension_dir = "C:/php/ext"
