What steps can be taken to troubleshoot and resolve PHP include path issues in a web application?

When encountering PHP include path issues in a web application, one common solution is to adjust the include_path directive in the php.ini configuration file to specify the correct path to the directories containing the included files. Another approach is to use the set_include_path() function within the PHP script to dynamically set the include path. Additionally, checking for typos or incorrect file paths in the include statements can help resolve the problem.

// Adjust the include_path directive in php.ini
// OR
// Use set_include_path() function within the PHP script
// Example:
set_include_path(get_include_path() . PATH_SEPARATOR . '/path/to/include/directory');

// Check for typos or incorrect file paths in the include statements
// Example:
include '/path/to/include/file.php';
