我需要有一个这样的数组
Array
(
[id] =>
[name] =>
[description] =>
[table_id] =>
[records] => Array
(
[0] => Array
(
[id] =>
[table_id] =>
[created] => 2016-01-15T09:19:36-0700
[updated] =>
[created_by] =>
[updated_by] =>
[fields] => Array
(
[created] =>
[Delivery Date] =>
[Total Price Including Shipping] =>
[Enquiry Status] =>
[Equipment Booked 1] =>
[Equipment Booked 2] =>
[Equipment Booked 3] =>
[Equipment Booked 4] =>
[Equipment Booked 5] =>
[Equipment Booked 6] =>
[Surname] =>
)
)
)
[record_count] => 1
)
我需要从 [记录] 中嵌套数组的最后一个元素中提取 [created] 字段。我尝试执行以下操作
$target_elems = $target.['record_count'];
//print_r($target_elems);
//echo $target_elems;
//echo $target.['records'].[$target_elems].['created'];
echo '<pre>'; print_r($target); echo '<pre/>';
bur 我总是得到数组到字符串的转换错误（注释行显然已经过测试）。
唯一生成的输出是
ArrayArrayArrayArray
正如你所说：- I need to extract the [created] field from the last element of the nested array in [records].
首先计算子数组records记录数，然后获取数据：
<?php
$count = count($target['records']); // count number of record in records sub-array
echo $target['records'][$count-1]['created']; // get last created from records array
?>
您可以通过以下方式获取created条记录的字段值。
$last_record = end($target['records']); // get the last record of an array
echo $last_record['created']; // print value of array key 'created'
希望它能帮助你:)
试试这样，
function ProcessData($arr){
foreach($target as $key => $value){
if( is_array($value) and !empty($value) ){
ProcessData($value);
}else{
if($key == 'created'){
echo $value;
}
}
}
}
