好吧,如果觉得这应该是非常简单并且通过像array_merge()或array_merge_recursive这样的函数来完成,但我无法弄明白.我有两个简单的数组,如下面的(简化)示例.我只是想根据它们的索引将它们合并到一个数组中.
$array 1：
- Array (
- [0] => Array (
- [ID] => 201
- [latLng] => 45.5234515,-122.6762071
- )
- [1] => Array (
- [ID] => 199
- [latLng] => 37.7931446,-122.39466520000002
- )
- )
等等…
$array2：
- Array (
- [0] => Array (
- [distance] => 1000
- [time] => 10
- )
- [1] => Array (
- [distance] => 1500
- [time] => 15
- )
- )
$desiredResult：
- Array (
- [0] => Array (
- [ID] => 201
- [latLng] => 45.5234515,-122.6762071
- [distance] => 1000
- [time] => 10
- )
- [1] => Array (
- [ID] => 199
- [latLng] => 37.7931446,-122.39466520000002
- [distance] => 1500
- [time] => 15
- )
- )
当我尝试使用合并函数合并这些时,我只能得到这个：
$unDesiredResult：
- Array (
- [0] => Array (
- [ID] => 201
- [latLng] => 45.5234515,-122.39466520000002
- )
- [2] => Array (
- [distance] => 1000
- [time] => 10
- )
- [3] => Array (
- [distance] => 1500
- [time] => 15
- )
- )
我需要循环将第二组推入第一组,还是可以使用现有功能完成？
我不认为有一个功能为你做这个,你将不得不循环.
- $result = array();
- foreach($array1 as $key=>$val){ // Loop though one array
- $val2 = $array2[$key]; // Get the values from the other array
- $result[$key] = $val + $val2; // combine 'em
- }
或者您可以将数据推送到$array1,因此您需要创建第3个数组：
- foreach($array1 as $key=>&$val){ // Loop though one array
- $val2 = $array2[$key]; // Get the values from the other array
- $val += $val2; // combine 'em
- }
