PHP Simple implementation of infinite class classification method, PHP infinite class classification

In this paper, we describe the simple implementation of an infinite class of PHP methods. Share to everyone for your reference, as follows:

Database structure:

CREATE TABLE IF not EXISTS ' city ' (' id ' int (one) not NULL auto_increment, ' name ' varchar () character Set UTF8 collate UT F8_unicode_ci NOT NULL default ' 0 ', ' parentid ' int (one) not null default ' 0 ' PRIMARY KEY (' id ')) engine=myisam default CHAR Set=latin1 auto_increment=7;

PHP Files:

$DB =new db ($Config [' Host '], $Config [' User '], $Config [' Password '], $Config [' Port '], $Config [' db '], $Config [' CharSet '] ); function findcity ($table, $id =0, $level =1) {  global $db;  $FINDSQL = "Select Id,name,parentid from $table the Where parentid={$id} ORDER by id";  $findResult = $db->getarray ($FINDSQL);  $num = $db->numrows;  $LOGOSTR = "|";  for ($i =0; $i < $level; $i + +) {  $logoStr. = "--";  }   if ($num!=0) {for   ($j =0; $j < $num; $j + +) {     echo{$LOGOSTR} {$findResult [$j][name]} ";        Findcity ($table, $findResult [$j] [' ID '], $level + 1);}}  Findcity (city);
