要实现无限递归的表记录级联删除，需要重写Zend_Db_Table的_cascadeDelete方法：

<?php /** * Zeal Extends of ZendFramework * * @category Zeal * @package Zeal_Db * @subpackage Table */ /** * @see Zend_Db */ require_once 'Zend/Db/Table/Abstract.php'; /** * Class for SQL table interface. * Extend for recurse cascade delete * * @category Zeal * @package Zeal_Db * @subpackage Table */ class Zeal_Db_Table_CascadeDeleteRecurse extends Zend_Db_Table_Abstract { /** * Called by parent table's class during delete() method. * * @param string $parentTableClassname * @param array $primaryKey * @return int Number of affected rows */ public function _cascadeDelete($parentTableClassname, array $primaryKey) { $rowsAffected = 0; foreach ($this->_getReferenceMapNormalized() as $rule => $map) { if ($map[self::REF_TABLE_CLASS] == $parentTableClassname && isset($map[self::ON_DELETE])) { switch ($map[self::ON_DELETE]) { case self::CASCADE: for ($i = 0; $i < count($map[self::COLUMNS]); ++$i) { $col = $this->_db->foldCase($map[self::COLUMNS][$i]); $refCol = $this->_db->foldCase($map[self::REF_COLUMNS][$i]); $where[] = $this->_db->quoteInto( $this->_db->quoteIdentifier($col, true) . ' = ?', $primaryKey[$refCol] ); } $depTables = $this->getDependentTables(); if(is_array($depTables) && count($depTables) > 0){ // 如果存在多级级联，递归调用。 $rowsToDel = $this->fetchAll($where); if($rowsToDel->count()) while(($row = $rowsToDel->current())){ $rowsAffected += $row->delete(); $rowsToDel->next(); } } else{ $rowsAffected += $this->delete($where); } break; default: // no action break; } } } return $rowsAffected; } }
