使用PHP构建JSON数据

Question

I would like to produce the following JSON output using PHP

{
"dataid": "An optional sourcetable identifier",
"columns": [
    {
        "colvalue": "Status",
        "coltext": "Status",
        "header": "Status",
        "sortbycol": "Status",
        "groupbyrank": null,
        "pivot": true,
        "result": false
    },
    {
        "colvalue": "Priority",
        "coltext": "Priority",
        "header": "Priority",
        "sortbycol": "Priority",
        "dataid": "An optional id.",
        "groupbyrank": 4,
        "pivot": false,
        "result": false
    },
    {
        "colvalue": "Team",
        "coltext": "Team",
        "header": "Team",
        "sortbycol": false,
        "dataid": "An optional id.",
        "groupbyrank": 1,
        "pivot": false,
        "result": false
    },
    {
        "colvalue": "Module",
        "coltext": "Module",
        "header": "Module",
        "sortbycol": "Module",
        "dataid": "An optional id.",
        "groupbyrank": 2,
        "pivot": false,
        "result": false
    },
    {
        "colvalue": "SLA",
        "coltext": "SLA",
        "header": "SLA",
        "sortbycol": "SLA",
        "dataid": "An optional id.",
        "groupbyrank": 3,
        "pivot": false,
        "result": false
    },
    {
        "colvalue": "Score",
        "coltext": "Score",
        "header": "Score",
        "sortbycol": "Score",
        "groupbyrank": null,
        "pivot": false,
        "result": true
    }
],
"rows": [
    {
        "Team": "Technical",
        "Module": "BASIS",
        "SLA": "Critical",
        "Priority": "High",
        "Status": "In Progress",
        "Score": "1",
        "Score2": "18.27"
    },
    {
        "Team": "Technical",
        "Module": "BASIS",
        "SLA": "Critical",
        "Priority": "High",
        "Status": "In Progress",
        "Score": "1",
        "Score2": "18.27"
    },

]

}

However i am stuck on how to combine my array which are hardcoded and my dynamic data (taken from MySQL row).

The following is my PHP code to generate the column and dataid which is static

$test = array(
        "dataid" => 'An optional sourcetable identifier',
        "columns" => array(
            array(
                'colvalue' => 'Status',
                'coltext' =>'Status',
                'header' =>'Status',
                'sortbycol' => 'Status',
                'groupbyrank' => null,
                'pivot' => true,
                'result' => false
            ),
            array(
                'colvalue' => 'Priority',
                'coltext' => 'Priority',
                'header' => 'Priority',
                'sortbycol' => 'Priority',
                'dataid' => 'An optional id.',
                'groupbyrank' => 4,
                'pivot' => false,
                'result' => false
            ),
        )
    );

What i am stuck with is how do combine it with my row data? Can someone help me with this.

Thanks

You can ammend existing arrays just by using a new key:

$test['rows'] = $yourRowDataAsArray;
