我有这个数组:
array(
"tour_0" => 1446,
"tour_1" => 1471,
"date-from-1471" => "2014-08-07",
"date-to-1471" => "2014-08-15",
"tour_2" => 30,
"date-from-30" => 2014-08-01,
"date-to-30" => 2014-08-05,
"tour_3" => 10
)
现在,我需要对它进行分类:
array(
"0" => array("ID" => 1446),
"1" => array("ID" => 1471, "from" => "2014-08-07", "to" => "2014-08-15"),
"2" => array("ID" => 30, "from" => "2014-08-07", "to" => "2014-08-15"),
"3" => array("ID" => 10),
)
我怎样才能完成这件事? 我尝试过各种各样的事情,但我似乎无法想出这个......
感谢并对标题感到抱歉,但我不知道如何描述它。
答案 0 :(得分:1)
这个怎么样?
$ret = [];
foreach($inputArray as $key => $value) {
if (preg_match('/^tour_([0-9]+)/', $key)) {
$ret[$value] = ["ID" => $value];
}
if (preg_match('/date-from-([0-9]+)/', $key, $matches)) {
$ret[$matches[1]]["from"] = $value;
}
if (preg_match('/date-to-([0-9]+)/', $key, $matches)) {
$ret[$matches[1]]["to"] = $value;
}
}
print_r($ret);
/*

足够接近? (这是非常繁琐的更改数组的键,考虑到它们是有序的(0,1,2,3,...),如果它们不是,也许你也可以保存顺序(在子阵列的另一项中)并且一旦形成这个数组就重新组合)
