Question

我有这个PhP代码，用户点击一个按钮，它会自动下载.csv文件，里面有不同类型的信息。所以这个.csv文件是用逗号分隔的，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除逗号之外的任何内容，因为我的一些数据有逗号，例如Location列有501A，501B等数据，它需要在单个单元格上。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。所以我只想问我如何更改分隔符并用逗号维护数据？谢谢！

<?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);

$seperator = "";
$comma = "";

foreach ($row as $name => $value){
    $seperator.= $comma. ''.str_replace('','""',$name);
    $comma=",";

}
$seperator .= "\n";

//echo $seperator;




mysqli_data_seek($rs2,0);

while ($row = mysqli_fetch_assoc($rs2)){


//$seperator = "";
$comma = "";

foreach ($row as $name => $value){

            $value = str_replace( array( "\r" , "\n", "\r\n", "\n\r" ) ,'' , $value);
            $value = str_replace('</b><br>','',$value);
            $value = str_replace('<b>','',$value);
            $value = str_replace('<br>','',$value);
            $value = str_replace('<br />','',$value);

    $seperator.= $comma. ''.str_replace('','""',$value);
    $comma=",";

    }
$seperator .= "\n";
}

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

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

您可以将fputcsv()用于csv格式的生成数据

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

修改

您的代码看起来会像这样：

<?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"; }

使用PHP函数，fputcsv将每一行放在一个数组中（每个列值将成为数组的一个项目），因此您不必担心里面的逗号。由于您是直接下载文件，因此请使用PHP输出作为文件句柄。请记住在输出开始之前设置标题。

$output = fopen('php://output', 'w');

// output the column headings/ values
fputcsv($output, array('Column 1', 'Column 2', 'Column 3');

PhP导出.csv将分隔符从逗号更改为其他人
