Two Functions 1 are used to generate the Tree Code:

The Code is as follows:
Function getTree ($ data, $ pId) { $ Tree = ''; Foreach ($ data as $ k => $ v) { If ($ v ['pid '] = $ pid) { $ V ['pid '] = $ this-> getTree ($ data, $ v ['id']); $ Tree [] = $ v; // Unset ($ data [$ k]); } } Return $ tree; }

Function 2 is converted to html code:

The Code is as follows:
Function procHtml ($ tree) { $ Html = ''; Foreach ($ tree as $ t) { If ($ t ['pid '] = '') { $ Html. =" {$ T ['fzname']} "; } Else { $ Html. =" ". $ T ['fzname']; $ Html. = $ this-> procHtml ($ t ['pid ']); $ Html = $ html ." "; } } Return $ html? ' '. $ Html .' ': $ Html; }
