PhP导出.csv将分隔符从逗号更改为其他

Question

我有这个 PhP 代码，用户点击一个按钮，它会自动下载一个 .csv 文件，里面有不同类型的信息。所以这个 .csv 文件是逗号分隔的，所以这意味着只要有逗号，指针就会转到下一个单元格。但我想将分隔符更改为逗号以外的任何内容，因为我的某些数据包含逗号，例如位置列包含 501A、501B 等数据，并且它需要位于单个单元格中。但是它会转到另一个单元格，因此当我以纵向打印时 id 不适合。所以我只是想问如何更改分隔符并用逗号维护数据？谢谢!

define("DB_HOST", "localhost");

function db_connect() {

  $db = mysqli_connect(DB_HOST, DB_USER, DB_PASS) or die("ERROR!");
  mysqli_select_db($db, DB_NAME);

  return $db;
}

$db = db_connect();
date_default_timezone_set("EST5EDT");
$date = date('m-d-Y,h.i.sa');

您可以使用 fputcsv()用于生成 csv 格式的数据

int fputcsv ( resource $handle , array $fields [, string $delimiter = "," [, string $enclosure = '"' [, string $escape_char = "\" ]]] )

编辑:

你的代码看起来像这样:

<?php
define("DB_HOST", "localhost");
define("DB_USER", "root");
define("DB_PASS", "");
define("DB_NAME", "envoy");
function db_connect() {

  $db = mysqli_connect(DB_HOST, DB_USER, DB_PASS) or die("ERROR!");
  mysqli_select_db($db, DB_NAME);

  return $db;
}

$db = db_connect();
date_default_timezone_set("EST5EDT");
$date = date('m-d-Y,h.i.sa');
$date2 = date('m/d/Y');
$filename = $date.'.csv';
$fp = fopen($filename,"w");

$sql2 = "SELECT sku as Sku,name as 'Brochure Name',location as Location FROM brochureinfo where modified LIKE '$date2' ORDER BY name  ";
$rs2 = mysqli_query($db, $sql2);
$total_records = mysqli_num_rows($rs2);
mysqli_close($db);

if ($total_records>0) {
    $row = mysqli_fetch_assoc($rs2);

    $delimiter = ';';
    $data = [];
    foreach ($row as $name => $value){
        $data[] = $name;
    }
    fputcsv($fp, $data, $delimiter);


    mysqli_data_seek($rs2,0);

    while ($row = mysqli_fetch_assoc($rs2)){
        fputcsv($fp, $row, $delimiter);
    }

    fclose($fp);

    header('Content-Type: text/csv');
    header("Content-Disposition: attachment; filename=$date.csv");
    header('Pragma: no-cache');

    echo $seperator;
}
else {
    fclose($fp);

    header('Content-Type: text/csv');
    header("Content-Disposition: attachment; filename=$date.csv");
    header('Pragma: no-cache');
    echo "No record modified today";
}
