使用此查询我得到了这个数组。但有些行重复一些不同的列。我想要做的是将这些不同的列作为父数组的多维数组中的单独数组。我尝试用Mysql group_by distinct子句来做这件事，但我无法做到。我认为最好的方法是通过php实现它。请给我一些帮助。谢谢 Myquery
$query = "SELECT "
. "a.emp_nmbr, a.emp_frstNm, a.emp_lstNm, a.emp_lclFrn, b.emp_dsgntn, b.emp_dprtmnt, b.emp_allwncs, b.emp_bscSlry, b.emp_sts, c.emp_lvsCtgry, c.emp_tknFrm, c.emp_tknTo "
. "FROM "
. "employee a "
. "LEFT JOIN "
. "emp_details b "
. "ON "
. "a.emp_nmbr = b.emp_nmbr "
. "LEFT JOIN "
. "leaves_details c "
. "ON "
. "a.emp_nmbr = c.emp_nmbr "
. "WHERE emp_lclFrn = 0 ";
. "LIMIT $page, $perPage ";
codeigniter模型函数执行查询。
function count_and_data($query) {
$query = $this->db->query($query);
$result = $query->result();
$count = $query->num_rows();
$data['count'] = $count;
$data['rows'] = $result;
return $data;
}
我得到的结果数组

这是一个快速流程，可以帮助您实现您的要求。
// collect all the unique data here
$holder = array();
foreach($data['rows'] as $data) {
// check with emp_nmbr = ophl3
if( ( $key = _finder($data->emp_nmbr, $holder) ) === false ) {
$holder[] = array(
'emp_nmbr'=>$data->emp_nmbr,
..........
'emp_lvData'=>array(
array('emp_lvsCtgry'=>$data->emp_lvsCtgry)
..........
)
);
}
else {
// emp_nmbr = ophl3 found now Merge Data Here..
if( ! empty( $data->emp_lvsCtgry ) ) {
$holder[$key]['emp_lvData'] =
array_merge(
$holder[$key]['emp_lvData'],
array('emp_lvsCtgry'=>$data->emp_lvsCtgry));
}
}
}
// Search Value in Muliti-dimentional array
function _finder($key, $array) {
if( ! is_array($array) || count($array) == 0 ) return false;
foreach( $array as $k=>$arr ){
if( in_array( $key, $arr ) ) {
return $key;
}
}
return false;
}
$holder保存所有唯一数组数据。
