我想以特定的方式从Array创建一个JSON。我的数组在开头看起来像这样:
array(2) {
[22]=>
array(8) {
["factor"]=>
array(2) {
[0]=>
string(2) "12"
[1]=>
string(1) "1"
}
["unit"]=>
array(2) {
[0]=>
string(6) "months"
[1]=>
string(5) "times"
}
["value"]=>
array(2) {
[0]=>
string(3) "2.5"
[1]=>
string(1) "2"
}
["planid"]=>
array(2) {
[0]=>
string(1) "1"
[1]=>
string(1) "1"
}
["position"]=>
array(2) {
[0]=>
string(22) "Test 1"
[1]=>
string(21) "Test 2"
}
["vouchervalue"]=>
array(2) {
[0]=>
string(1) "0"
[1]=>
string(1) "0"
}
["vouchertype"]=>
array(2) {
[0]=>
string(0) ""
[1]=>
string(0) ""
}
["vat"]=>
array(2) {
[0]=>
int(19)
[1]=>
int(19)
}
}
[23]=>
array(8) {
["factor"]=>
array(2) {
[0]=>
string(2) "12"
[1]=>
string(1) "1"
}
["unit"]=>
array(2) {
[0]=>
string(6) "months"
[1]=>
string(5) "times"
}
["value"]=>
array(2) {
[0]=>
string(3) "2.5"
[1]=>
string(1) "2"
}
["planid"]=>
array(2) {
[0]=>
string(1) "1"
[1]=>
string(1) "1"
}
["position"]=>
array(2) {
[0]=>
string(22) "Test 3"
[1]=>
string(21) "Test 4"
}
["vouchervalue"]=>
array(2) {
[0]=>
string(1) "0"
[1]=>
string(1) "0"
}
["vouchertype"]=>
array(2) {
[0]=>
string(0) ""
[1]=>
string(0) ""
}
["vat"]=>
array(2) {
[0]=>
int(19)
[1]=>
int(19)
}
}
}
这就是JSON的样子:
string(354) "{"factor":[["12","1"],["12","1"]],"unit":[["months","times"],["months","times"]],"value":[["2.5","2"],["2.5","2"]],"planid":[["1","1"],["1","1"]],"position":[["Test 1","Test 2"],["Test 3","Test 4"]],"vouchervalue":[["0","0"],["0","0"]],"vouchertype":[["",""],["",""]],"vat":[[19,19],[19,19]]}"
但我想这样做:
string(214) "{"factor":["12", "1","12","1"],"unit":["months", "times","months","times"],"value":["2.5","2","2.5", "2"],"planid":["1","1","1","1"],"position":["Test 1","Test 2", "Test 3", "Test 4"],"vouchervalue":["0","0","0","0"],"vouchertype":["","","",""],"vat":[19,19,19,19]}"
这个想法是每个订单都可以包含多个位置,可用于创建可以在应用程序的其余部分中使用的JSON(有一个使用JSON的表)。
好吧,我不知道如何解决这个问题所以我对任何暗示感到高兴: - )

我们假设你有数组$ a中的数据。
$a = array(
array(
'factor'=> array( '12', '1' ),
'unit'=> array( 'months', 'times' ),
'value'=> array( '2.5', '2' ),
'planid'=> array( '1', '1' ),
'position'=> array( 'Test 1', 'Test 2' ),
'vouchervalue'=> array( '0', '0' ),
'vouchertype'=> array( '', '' ),
'vat'=> array( 19, 19 ),
),
array(
'factor'=> array( '12', '1' ),
'unit'=> array( 'months', 'times' ),
'value'=> array( '2.5', '2' ),
'planid'=> array( '1', '1' ),
'position'=> array( 'Test 3', 'Test 4' ),
'vouchervalue'=> array( '0', '0' ),
'vouchertype'=> array( '', '' ),
'vat'=> array( 19, 19),
),
);
在您的示例中,这包含两个要组合的数组。这是一种方式:
$b = array();
foreach( $a[0] as $k=>$v ) {
if ( isset( $a[1][$k] ) ) // Add keys in both arrays
$b[$k] = array_merge( $a[0][$k], $a[1][$k] );
else // Add keys in only first array
$b[$k] = $a[0][$k];
}
foreach( $a[1] as $k=>$v ) {
if ( !isset( $a[0][$k] ) ) // Add keys in only second array
$b[$k] = $a[1][$k];
}
echo json_encode( $b );
这遍历第一个数组。如果键('factor','unit')在两个数组中都可用,它会合并它们,否则它只会添加数组。
其次,它遍历第二个数组并添加第一遍中未添加的数组(如果该键不在第一个数组中)。
在你的情况下,数组似乎有相同的键集,第二遍可能没有必要,但只是为了确保......
结果如下:
{"factor":["12","1","12","1"],"unit":["months","times","months","times"],"value":["2.5","2","2.5","2"],"planid":["1","1","1","1"],"position":["Test 1","Test 2","Test 3","Test 4"],"vouchervalue":["0","0","0","0"],"vouchertype":["","","",""],"vat":[19,19,19,19]}
如果你不想让json中的数字进行字符串编码,比如“12”而不是12,请将jSON_NUMERIC_CHECK添加到json_encode
echo json_encode( $b, JSON_NUMERIC_CHECK );
{"factor":[12,1,12,1],"unit":["months","times","months","times"],"value":[2.5,2,2.5,2],"planid":[1,1,1,1],"position":["Test 1","Test 2","Test 3","Test 4"],"vouchervalue":[0,0,0,0],"vouchertype":["","","",""],"vat":[19,19,19,19]}

您正在寻找array_merge_recursive()
。根据文档:
array_merge_recursive()将一个或多个数组的元素合并在一起,以便将一个值的值附加到前一个数组的末尾。它返回结果数组。
如果输入数组具有相同的字符串键,则这些键的值将合并到一个数组中,并且这是递归完成的,因此如果其中一个值是数组本身,则该函数将合并它另一个数组中的相应条目。但是,如果数组具有相同的数字键,则后面的值不会覆盖原始值,但会附加。
在答案中使用上面列出 @HasseBjork 的示例输入(基于您的原始输入):
$a = array(
array(
'factor'=> array( '12', '1' ),
'unit'=> array( 'months', 'times' ),
'value'=> array( '2.5', '2' ),
'planid'=> array( '1', '1' ),
'position'=> array( 'Test 1', 'Test 2' ),
'vouchervalue'=> array( '0', '0' ),
'vouchertype'=> array( '', '' ),
'vat'=> array( 19, 19 ),
),
array(
'factor'=> array( '12', '1' ),
'unit'=> array( 'months', 'times' ),
'value'=> array( '2.5', '2' ),
'planid'=> array( '1', '1' ),
'position'=> array( 'Test 3', 'Test 4' ),
'vouchervalue'=> array( '0', '0' ),
'vouchertype'=> array( '', '' ),
'vat'=> array( 19, 19),
),
);
您需要做的就是:
echo json_encode(array_merge_recursive($a[0], $a[1]));
