我有问题显示两个数组与具体结构，我不知道是否可能。我有两个数组多维
美元Array (
[0] => Array
( [id] => 1
[total] => 4
[label] => one
[url] => 0 )
[1] => Array
( [id] => 2
[total] => 2
[label] => two
[url] => 500 )
[2] => Array
( [id] => 3
[total] => 9
[label] => three
[url] => -100 )
[3] => Array
( [id] => 5
[total] => 15
[label] => five
[ten] => 100 )
)
$ b
Array (
[0] => Array
( [id] => 1
[total] => 2
[label] => one
[url] => 100 )
[1] => Array
( [id] => 4
[total] => 4
[label] => four
[url] => -100 )
[2] => Array
( [id] => 3
[total] => 1
[label] => three
[url] => 200 )
[3] => Array
( [id] => 5
[total] => 1
[label] => five
[ten] => -100 )
)
[4] => Array
( [id] => 7
[total] => 1
[label] => seven
[ten] => 500 )
)
[5] => Array
( [id] => 6
[total] => 1
[label] => six
[ten] => 200 )
)
我希望这个结构通过标签
列出数组$a $b
--- ---
one one
two -
three three
- four
five five
- six
- seven
这是可能的吗?
Thanks in advance
首先，您需要使用array_multisort按id值对数组进行排序，如
// Define an test array
$array = array(
0 => array(
"id" => 1,
"total" => 4,
"label" => "one",
"url" => 0
),
1 => array(
"id" => 7,
"total" => 10,
"label" => "seven",
"url" => 0
),
2 => array(
"id" => 2,
"total" => 13,
"label" => "two",
"url" => 0
)
);
// Get a "id" list from the array
$ids = array();
foreach ($array as $key => $row) {
$ids[$key] = $row['id'];
}
array (size=3)
0 =>
array (size=4)
'id' => int 1
'total' => int 4
'label' => string 'one' (length=3)
'url' => int 0
1 =>
array (size=4)
'id' => int 2
'total' => int 13
'label' => string 'two' (length=3)
'url' => int 0
2 =>
array (size=4)
'id' => int 7
'total' => int 10
'label' => string 'seven' (length=5)
'url' => int 0
对于显示，我们只需要一个循环并检查$findIdNode["id"] == $i节点是否存在。
// Display the result
for($i=1; $i<=end($array)["id"]; $i++) {
// Check if the "id" value exist in $array
$findIdNode = $array[array_search($i, array_column($array, "id"))];
if($findIdNode["id"] == $i)
echo $findIdNode["label"]."<br />";
else
echo "-<br />";
}
one
two
