這篇文章主要介紹了php遞歸使用示例(php遞歸函數),包括遞歸獲得角色ID字符串、遞歸獲取級聯角色信息數組、通過父角色的id獲取子角色信息,需要的朋友可以參考下
代碼如下: //遞歸獲得角色ID字符串 function explodeRole($roleObj, &$resultStr){ if(0 < count($roleObj->childRoleObjArr)){ foreach($roleObj->childRoleObjArr as $childRoleObj){ if('' == $resultStr){ $resultStr .= "{$childRoleObj->id}"; }else{ $resultStr .= ", {$childRoleObj->id}"; } explodeRole($childRoleObj, $resultStr); } } } //遞歸獲取級聯角色信息數組 function makeRoleRelation(&$roleObjArr){ foreach($roleObjArr as $item){ $item->childRoleObjArr = getRoleObjArrByParentId($item->id); if(0 < count($item->childRoleObjArr)){ makeRoleRelation($item->childRoleObjArr); } } } //通過父角色的id獲取子角色信息 function getRoleObjArrByParentId($parentid){ $operCOGPSTRTSysRole = new COGPSTRTSysRole(); $operCOGPSTRTSysRole->setColumn($operCOGPSTRTSysRole->getAllColumn()); $operCOGPSTRTSysRole->setWhere("parentroleid={$parentid}"); $roleObjArr = $operCOGPSTRTSysRole->convResult2ObjArr($operCOGPSTRTSysRole->selectTable()); return isset($roleObjArr)?$roleObjArr:array(); }
