What are the common reasons for PHP extensions not loading properly?

Common reasons for PHP extensions not loading properly include incorrect configuration settings in php.ini, missing or incompatible extension files, conflicts with other extensions, or insufficient permissions to access the extension files. To solve this issue, you can check the php.ini file for correct extension paths, ensure the extension files are present and compatible with your PHP version, resolve any conflicts with other extensions, and adjust file permissions if necessary.

; Check php.ini for correct extension paths
extension_dir = "ext"

; Ensure extension files are present and compatible
extension=example_extension.so

; Resolve conflicts with other extensions
; Disable conflicting_extension.so

; Adjust file permissions if necessary
chmod -R 755 /path/to/extension_files
