Laravel：获取数据数组并使用 For 循环
我正在尝试获取数据数组并使用 For 循环。所以我有一个名为“颜色”的数组，我想用 For 循环数组。但我在结果上遇到了一些麻烦。我已经尝试在 foreach 中更改数组，但我不知道如何获得我想要的结果。
结果 ：
"data": [
{
"title": "get data users",
"function_name": "selectDataUser",
"function_drop": "selectDataUser",
"type_of_chart": "Pie",
"embed": null,
"created_at": "2019-06-15 03:26:09.000",
"updated_at": null,
"data_chart": [
{
"name": "Administrator",
"total": "100",
"color": "0xFF888888" //color cannot be the same
},
{
"name": "Staff",
"total": "100",
"color": "0xFF888888" //the color must be different
},
{
"name": "Super Administrator",
"total": "1",
"color": "0xFF888888" //this is not result what I want.
}
],
}
]
我想要这样的回应：
"data": [
{
"title": "get data users",
"function_name": "selectDataUser",
"function_drop": "selectDataUser",
"type_of_chart": "Pie",
"embed": null,
"created_at": "2019-06-15 03:26:09.000",
"updated_at": null,
"data_chart": [
{
"name": "Administrator",
"total": "100",
"color": "0xFF000000" //all this color different
},
{
"name": "Staff",
"total": "100",
"color": "0xFF444444" //the color different
},
{
"name": "Super Administrator",
"total": "1",
"color": "0xFF888888" //this is result what I want.
}
],
}
]

MM们
$set是数组，不能作为字符串赋值。我的建议是更改以下代码： for ($i=0; $i < count($data_chart) ; $i++) { $set = $color[$i]; //Get data array color } foreach($data_chart as $row){ $row->color = $set; }到 $i=0; foreach($data_chart as $row){ $row->color = $color[$i]; $i++; }但是如果您的$data_chart计数超过$color计数，它将返回错误，以便更好地处理使用以下代码： $i=0; foreach($data_chart as $row){ if(isset($color[$i])){ $row->color = $color[$i]; $i++; } else{ $i=0; } }
