What considerations should be made when handling character encoding and collation settings in PHP scripts, webpages, and databases?

When handling character encoding and collation settings in PHP scripts, webpages, and databases, it is important to ensure consistency across all components to avoid issues with displaying and storing data correctly. This includes setting the appropriate character encoding in PHP scripts using functions like `mb_internal_encoding()`, specifying the charset in HTML meta tags, and configuring the collation settings in database tables to match the character encoding used. 

// Set character encoding in PHP script
mb_internal_encoding('UTF-8');

// Specify charset in HTML meta tag
<meta charset="UTF-8">

// Configure collation settings in MySQL database table
ALTER TABLE table_name CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
