我正在寻找一种解决方案，从foreach循环中的平面数组数据创建关联数组：
我有一个csv/xls文件，第一行有标题，下一行有数据。
第1行：标题行2,3,4,5：数据
阵列看起来：
array(3) {
[0]=>
array(7) {
[0]=>
string(3) "country"
[1]=>
string(7) "state"
[2]=>
string(3) "city"
[3]=>
string(5) "name"
[4]=>
string(4) "address"
[5]=>
string(6) "gender"
[6]=>
string(6) "status"
}
[1]=>
array(7) {
[0]=>
string(12) "Argentina"
[1]=>
string(12) "Corrientes"
[2]=>
string(12) "Corrientes"
[3]=>
string(12) "Jorge"
[4]=>
string(12) "Avenida Avellaneda 12"
[5]=>
string(12) "Masculino"
[6]=>
string(12) "Activo"
}
[2]=>
array(7) {
[0]=>
string(12) "Argentina"
[1]=>
string(12) "Chaco"
[2]=>
string(12) "Resistencia"
[3]=>
string(12) "Mariano"
[4]=>
string(12) "Avenida Peron 12"
[5]=>
string(12) "Masculino"
[6]=>
string(12) "Activo"
}
}
最后我需要得到的结果是：
array(2) {
[0]=>
array(7) {
['country']=>
string(12) "Argentina"
['state']=>
string(12) "Corrientes"
['city']=>
string(12) "Corrientes"
['name']=>
string(12) "Jorge"
['address']=>
string(12) "Avenida Avellaneda 12"
['gender']=>
string(12) "Masculino"
['status']=>
string(12) "Activo"
}
[1]=>
array(7) {
['country']=>
string(12) "Argentina"
['state']=>
string(12) "Chaco"
['city']=>
string(12) "Resistencia"
['name']=>
string(12) "Mariano"
['address']=>
string(12) "Avenida Peron 12"
['gender']=>
string(12) "Masculino"
['status']=>
string(12) "Activo"
}
}
$array = $your_flat_array;
for ($i = 1; $i < count($array); $i++) {
$new_array[$i-1] = [];
foreach ($array[$i] as $key => $value) {
$new_array[$i-1][$array[0][$key]] = $value;
}
}
print_r($new_array);
从平面阵列创建多维阵列
你已经有了一个多维数组，因为你在一个数组中有数组。
在这种特定情况下，您可以将array_splice（）与array_combine（）结合使用。
试试这个：
$oldArray = array(
array( "country", "state", "city", "name" ),
array( "Argentina", "Corrientes", "Corrientes", "Jorge" ),
array( "Argentina", "Chaco", "Resistencia", "Mariano" )
);
$newArray = array_splice( $oldArray, 1 );
foreach( $newArray as $index => $array ) {
$newArray[$index] = array_combine( $oldArray[0], $array );
}
echo "<pre>";
var_dump( $newArray );
输出：
array(2) {
[0]=>
array(4) {
["country"]=>
string(9) "Argentina"
["state"]=>
string(10) "Corrientes"
["city"]=>
string(10) "Corrientes"
["name"]=>
string(5) "Jorge"
}
[1]=>
array(4) {
["country"]=>
string(9) "Argentina"
["state"]=>
string(5) "Chaco"
["city"]=>
string(11) "Resistencia"
["name"]=>
string(7) "Mariano"
}
}
您所要做的就是从数组中删除第一项（头行）：
array_splice($yourArray, 0, 1);
