PHP を使用して Excel エクスポートで MySQL データを個々のセルに分割する方法

Exporting MySQL Data to Excel in PHP

Problem:

When exporting MySQL data to an Excel file, the text is combined into a single cell instead of being separated into individual cells.

Solution:

To export MySQL data to Excel with each row value in a separate cell, modify your PHP code as follows:

<code class="php">// ...
while (($row = mysql_fetch_row($result)) != FALSE) {
    foreach ($row as $value) {
        if (is_null($value)) {
            $line .= 'NULL' . "\t";
        } else {
            $value = str_replace('"', '""', $value);
            $value = '"' . $value . '"' . "\t";
            $line .= $value;
        }
    }
    $line = trim($line) . "\n";
    $line = preg_replace('/\r\n|\r|\n/', "\n", $line);  // Normalize newlines

    $data .= $line;
}
// ...</code>

Explanation:

• Each row value is now iterated over and encapsulated within double quotes to comply with Excel's format.
• Newlines are normalized to ensure consistency in the Excel file.

Updated Code:

<code class="php">$queryexport = ("
SELECT username,password,fullname FROM ecustomer_users
WHERE fk_customer='" . $fk_customer . "'
");

$result = mysql_query($queryexport);
$header = '';

for ($i = 0; $i < $count; $i++) {
    $header .= mysql_field_name($result, $i) . "\t";
}

while (($row = mysql_fetch_row($result)) != FALSE) {
    $line = '';
    foreach ($row as $value) {
        if (is_null($value)) {
            $line .= 'NULL' . "\t";
        } else {
            $value = str_replace('"', '""', $value);
            $value = '"' . $value . '"' . "\t";
            $line .= $value;
        }
    }
    $line = trim($line) . "\n";
    $line = preg_replace('/\r\n|\r|\n/', "\n", $line);  // Normalize newlines

    $data .= $line;
}

header("Content-type: application/vnd.ms-excel; name='excel'");
header("Content-Disposition: attachment; filename=exportfile.xls");
header("Pragma: no-cache");
header("Expires: 0");

// output data
echo $header . "\n" . $data;

mysql_close($conn);</code>
