When you export an Excel table, it is originally a field, and the first time you export it to the second line

When you export an Excel table, it is originally a field, and when you export it comes to the second line
Start Export
Header ("Content-type:application/vnd.ms-excel");
Header ("Content-disposition:attachment;filename=xueyuan_list_data.xls");

Echo mb_convert_encoding (' remarks ', ' GBK ', ' UTF-8 '). " \ t ";

$xuhao = 1;
foreach ($arr _xueyuan_list as $arr)
{
echo "\ n";
Echo $xuhao. "\ t";
Echo mb_convert_encoding ($arr [' Beizhu '], ' GBK ', ' UTF-8 '). " \ t ";
$xuhao = $xuhao + 1;
}

Since the data Beizhu at the time of submission is textarea, so beizhu this field will contain a newline character, when exported, once the content has a newline, then the second line will be displayed to the Excel table in another row, But what I want is beizhu. All the content in this field is only displayed in the "Remarks" box in the Excel table, what should I do?

Tested without replacing the carriage return line
Just wrap the output string in double quotes.
