PHP 将 mysql 转换为 excel

Question

正在将 PHP 转换为 Excel，但在 Excel 文件中遇到问题，它没有在自己的单元格中添加每一行。它的外观如下:https://www.dropbox.com/s/64lz7lqy8z7x72j/export.csv 它把它写入第一个单元格，看起来它已经写入了所有单元格。

这是 PHP 代码:

<?php

$conn = mysql_connect('localhost', 'root', '') or die(mysql_error());
mysql_select_db('chart', $conn) or die(mysql_error($conn));

$result = mysql_query('SELECT * FROM chartgoogle', $conn) or die(mysql_error($conn));

header('Content-Type: text/csv'); // tell the browser to treat file as CSV
header('Content-Disposition: attachment;filename=export.csv'); // tell browser to download a file in user's system with name export.csv

$row = mysql_fetch_assoc($result); // Get the column names
if ($row) {
    outputcsv(array_keys($row)); // It wil pass column names to outputcsv function
}

while ($row) {
    outputcsv($row);    // loop is used to fetch all the rows from table and pass them to outputcsv func
    $row = mysql_fetch_assoc($result);
}

function outputcsv($fields) {
    $separator = '';
    foreach ($fields as $field) {

        echo $separator . $field;
        $separator = ',';        // Separate values with a comma
    }
    echo "\r\n";     //Give a carriage return and new line space after each record
}

?>

Answer 1

试试这个:

function outputcsv($fields) {
    $csv = '';
    foreach ($fields as $field) {
        $csv .= '"' . $field . '",';
    }
    $csv .= "\r\n";     //Give a carriage return and new line space after each record
    echo $csv;
}

查看字段前后的双引号。 CSV 文件通常使用双引号作为闭包。他们称之为文本限定符。
