I needed something to do smart capitalization of names entered by users. While looking through thousands of user-entered names, I realized that there were three types of people: those that typed in all lower-case, all upper-case, or mixed case. examples: john smith JANE DOE Jeanne de Boer Bobby-Jo MacDonald I realized that people with intercapitalization in their names tended to type in mixed-case, so I made a function to do capitalization to names that were either all lower-case or all upper-case, and to leave mixed-case alone. I believe that this takes care of many internationalization issues in a subtle, intuitive, and user-empowering manner. Call it like this: print my_ucwords ( 'BRYON THUR' ); print my_ucwords ( 'chris steinberg' ); print my_ucwords ( 'Mike van Lammeren' ); function my_ucwords( $given_string ) { if( preg_match( '/[A-Z]/', $given_string ) and preg_match( '/[a-z]/', $given_string ) ) { # mixed-case detected, so don't touch string return $given_string; } return ucwords( strtolower( $given_string ) ); }
