Php 将数组转换为更具可读性和逻辑性的结构
我有一个大约200条记录的数组，如下所示：Php 将数组转换为更具可读性和逻辑性的结构,php,arrays,Php,Arrays,我有一个大约200条记录的数组，如下所示： [0] => Array ( [sid] => 54 [sname] => vISL User book [sdate] => 2012-03-01 00:00:00 [pid] => 262 [cid] => 95 [at] =>

获得所需阵列结构的最佳方法是什么 我会说循环遍历数组，然后使用
var\u export$tmp = Array();
$out = Array();
foreach($input as $row) {
$tmp[$row['sid']][] = $row;
}
foreach($tmp as $key=>$rows) {
$tmp[$key] = Array(
"sid" =>$rows[0]['sid'],
"sname"=>$rows[0]['sname'],
"sdate"=>$rows[0]['sdate'],
"parr" =>Array()
);
foreach($rows as $row) {
$tmp[$key]['parr'][] = Array(
"pid" =>$row['pid'],
"cid" =>$row['cid'],
"at" =>$row['at'],
"amount" =>$row['amount'],
"psdate" =>$row['psdate'],
"first_name"=>$row['first_name'],
"last_name" =>$row['last_name'],
"pcid" =>$row['pcid'],
"cname" =>$row['cname']
);
}
}
$out = array_values($tmp);
file_put_contents("tmp.php",'<?php $data = '.var_export($out,true).'; ?>');
$tmp=Array（）；
$out=Array（）；
foreach（$行输入）{
$tmp[$row['sid'][]=$row；
}
foreach（$tmp作为$key=>$rows）{
$tmp[$key]=数组(
“sid”=>$rows[0]['sid']，
“sname”=>$rows[0]['sname']，
“sdate”=>$rows[0]['sdate']，
“parr”=>数组（）
);
foreach（$行作为$行）{
$tmp[$key]['parr'][]=数组(
“pid”=>$row['pid']，
“cid”=>$row['cid']，
“at”=>$row['at']，
“金额”=>$row[“金额”]，
“psdate”=>$row['psdate']，
“first_name”=>$row['first_name']，
“姓氏”=>$row[“姓氏”]，
“pcid”=>$row['pcid']，
“cname”=>$row['cname']
);
}
}
$out=数组_值（$tmp）；
文件内容（“tmp.php”，”；
var\u export$tmp = Array();

我假定您从联接查询中获得这些数组结果。 我认为如果你把这些数据从数据库中分离出来，那就容易多了。 因此，您的问题类似于此线程： 无论如何，您可以尝试以下方法：
$pk = 'sid'; // record pk
$pkKeys = array(
'pid' => array( // subRecord pk
'parr' => array( // subRecords array key => array(subRecord names)
'pid',
'cid',
'amount',
'psdate',
'pcid',
),
),
);
$resultArr = array();
array_walk($records,
function ($val, $key) use (&$resultArr, $pkKeys, $pk) {
$mapped = array();
foreach ($val as $itemKey => $item) {
if (in_array($itemKey, array_keys($pkKeys))) {
$populateData = $pkKeys[$itemKey];
$subRecordPk = key($populateData);
foreach($populateData[$subRecordPk] as $populateKey) {
if ($subRecordPk !== $populateKey) {
$resultArr[$val[$pk]][$subRecordPk][$val[$itemKey]][$populateKey]
= $val[$populateKey];
$mapped[$populateKey] = $populateKey;
}
}
} else if (!in_array($itemKey, $mapped)){
$resultArr[$val[$pk]][$itemKey] = $val[$itemKey];
}
}
}
);
您是如何读取数据的？答案通常是您必须自己创建此自定义数组。您是如何读取数据的？答案通常是您必须自己创建此自定义数组。
