How to write fixed width text file with PHP

Take a look at the str_pad method. E.g.

str_pad('Somevalue', 20, " ", STR_PAD_LEFT);

Will left-pad the string "Somevalue" with spaces, giving

"           Somevalue"

Whereas

str_pad('Somevalue', 20);

Will right-pad the string with spaces, giving:

 "Somevalue           "
