José Luis Sánchez Navarro in avemundi writes that he has often been asked how to set up a tree structure in a database; his program El Puchero (program for the management of recipes) does exactly this. The source code for creating a tree structure of 5 levels deep is given in his article.
Jose A. Suárez in chochurro comments on the solution for setting up a tree structure in a database presented in avemundi and presents an alternative solution.
[Both of these solutions above seem unsatisfactory to me. I have a nagging memory from my early days in programming that it is possible to set up a tree structure using pointers that is infinitely extendible without requiring massive nested if statements in code or numerous tables to be created. I suspect the knowledge of data structures and algorithms that was painfully acquired by our ancestors has perhaps been lost by later generations.]
clbustos in Php y otras yerbas writes that one of the more pleasant things about programming in PHP on Windows is the PHP manual in CHM format. Moving to Linux, he found xchm which does not have nearly the features and functionality of the Windows version. Searching in Linux Links he found Dox which is just the "prescription that the doctor ordered" In his article, he gives a short example of the extendibility of Dox.
