在PHP中下载CSV时，列数据更改为不同的格式。我怎样才能阻止这一切？

当页面加载时，我正在使用PHP在服务器中创建csv。我将数据附加到$output，它在页面加载期间创建csv。我有一个列，它的帐号类似于（6280720003789856）。它在我的网页中看起来是正确的，但当我以CSV形式下载数据时，它会自动更改为（6.28072E+15）。我怎样才能阻止这种变化

代码如下

<?php
    $date_from = $_REQUEST['date_from'];
    $date_to = $_REQUEST['date_to'];
    $procedure = "call contract_compliance_givecentral_test1('".$date_from."','".$date_to."')";
    $conn2 = new MyConnection;
    $conn2->Connect();
    $rs2 = $conn2->ExecSQL($procedure);
    $output = '';
    $givecentral_contract = "Documents/givecentral_contract.csv";
    $filename = $givecentral_contract;
    $fp = @fopen($filename, "w+");
    $totalRows_rsnf_count = mysqli_num_rows($rs2);

    if ($totalRows_rsnf_count > 0) 
    { 
    // Show if recordset not empty 
    ?>  
    <div class="container" style="padding-left: 25px!important;padding-right: 25px!important;" id="printable_area">
     <div class="head">Contract Compliance - Givecentral
