我试图根据其创建的＆＃39;来检索记录。 timestamp列，其中昨天是开始日期，检索记录直到当月开始
$h_msg1 = m_chat_history::where('employee_id',$request->other_id)->whereNull('to_group')->where('to_employee_id',$request->id)->whereBetween('created_at', [
Carbon::parse('yesterday')->startOfDay(),
Carbon::now()->endOfMonth(),
])->get();
但不幸的是，它会抛出我的空洞结果，任何帮助，想法，线索，建议，建议吗？

尝试以下代码
$first_day_this_month = date('Y-m-01 H:s:i');
$yesterDay = date('Y-m-d H:s:i',strtotime("-1 days"));
$record = m_chat_history::whereBetween('created_at',[$first_day_this_month, $yesterDay])->get();

根据你的消息，你需要使用 startOfMonth ：
var zData = createData();
var xData = d3.range(0, zData.length);
var yData = d3.range(0, zData[0].length);
var data = [ {
z: zData,
x: xData,
y: yData,
type: 'contour',
colorscale: 'Jet',
showscale: false,
autocontour: false,
contours: {
start: -5,
end: 3,
size: 0.5
}
}];
var layout = {
margin: {
b: 0,
l: 0,
r: 0,
t: 0
},
height: 600,
width: 600,
title: '',
xaxis: {
ticks: '',
showticklabels: false
},
yaxis: {
ticks: '',
showticklabels: false
}
};
Plotly.newPlot('graph', data, layout, {displayModeBar: false});
function createData(){
var data = [
