如何在PHP中合并2个json文件，其中1个是数组

Question

我用PHP在不同的表中创建了json。返回的1个json对象是一个数组。如何将第二个都合并为第一个的子数组。我想通过单个get将其作为单个json发送到Xamarin表单（android）

PHP数组合并给出参数2不是数组

Json1
{
    "employeeid": "1123",
    "employeename": "EMP 001 NAME",
    "mMacID": "E0138",
    "machinename": "FOS",
    "iscleaning": 1,
    "isperforming": 1,
    "isverifying": 1,
    "cSeqno": 1,
    "cMacID": "E0138",
    "cInterval": 112,
    "cCleanOperationMaxTime": 300,
    "cPerformOperationMaxTime": 600,
    "oSequenceID": 6,
    "oMacID": "E0138",
    "oItemNumber": " ",
    "oBatchNumber": " ",
    "oPONumber": " ",
    "oCompletedOperation": 0,
    "oComplOperStartTime": 0,
    "oCompOperEndndTime": 0,
    "oOperationToContinue": 1
}

Json2 (Array)
[
    {
        "pMachineID": "E0138",
        "pmachinetoLocationSequence": 1,
        "pLocationNumber": 1,
        "pLocationName": "TestLoc1",
        "pLocationInterval": 12,
        "pImageRequiredForVerifying": 1,
        "pErrorFound": 0
    },
    {
        "pMachineID": "E0138",
        "pmachinetoLocationSequence": 1,
        "pLocationNumber": 2,
        "pLocationName": "TestLoc2",
        "pLocationInterval": 15,
        "pImageRequiredForVerifying": 0,
        "pErrorFound": 0
    },
    {
        "pMachineID": "E0138",
        "pmachinetoLocationSequence": 1,
        "pLocationNumber": 3,
        "pLocationName": "TESTLOC3",
        "pLocationInterval": 18,
        "pImageRequiredForVerifying": 0,
        "pErrorFound": 0
    },
    {
        "pMachineID": "E0138",
        "pmachinetoLocationSequence": 1,
        "pLocationNumber": 1,
        "pLocationName": "LOC1",
        "pLocationInterval": 12,
        "pImageRequiredForVerifying": 0,
        "pErrorFound": 0
    }
]

我想要第二个作为第一个数组。

只需解码2个JSON字符串，然后将数组添加到此类中

$js1 = '{
    "employeeid": "1123",
    "employeename": "EMP 001 NAME",
    "mMacID": "E0138",
    "machinename": "FOS",
    "iscleaning": 1,
    "isperforming": 1,
    "isverifying": 1,
    "cSeqno": 1,
    "cMacID": "E0138",
    "cInterval": 112,
    "cCleanOperationMaxTime": 300,
    "cPerformOperationMaxTime": 600,
    "oSequenceID": 6,
    "oMacID": "E0138",
    "oItemNumber": " ",
    "oBatchNumber": " ",
    "oPONumber": " ",
    "oCompletedOperation": 0,
    "oComplOperStartTime": 0,
    "oCompOperEndndTime": 0,
    "oOperationToContinue": 1
}';

$js2 = '[
    {
        "pMachineID": "E0138",
        "pmachinetoLocationSequence": 1,
        "pLocationNumber": 1,
        "pLocationName": "TestLoc1",
        "pLocationInterval": 12,
        "pImageRequiredForVerifying": 1,
        "pErrorFound": 0
    },
    {
        "pMachineID": "E0138",
        "pmachinetoLocationSequence": 1,
        "pLocationNumber": 2,
        "pLocationName": "TestLoc2",
        "pLocationInterval": 15,
        "pImageRequiredForVerifying": 0,
        "pErrorFound": 0
    },
    {
        "pMachineID": "E0138",
        "pmachinetoLocationSequence": 1,
        "pLocationNumber": 3,
        "pLocationName": "TESTLOC3",
        "pLocationInterval": 18,
        "pImageRequiredForVerifying": 0,
        "pErrorFound": 0
    },
    {
        "pMachineID": "E0138",
        "pmachinetoLocationSequence": 1,
        "pLocationNumber": 1,
        "pLocationName": "LOC1",
        "pLocationInterval": 12,
        "pImageRequiredForVerifying": 0,
        "pErrorFound": 0
    }
]';

$j1 = json_decode($js1);
$j2 = json_decode($js2);

// You may want to give this a more sensible name than `theArrays`
$j1->theArrays = $j2;

print_r($j1);

$new_json_string = json_encode($j1);

echo $new_json_string;

print_r($j1)的结果

您可以使用json_decode和array_merge来解决这个问题

$json1ToArray = json_decode($json1, true);
$json2ToArray = json_decode($json2, true);
$res = array_merge($json1ToArray, $json2ToArray);
print_r($res);
