如何使用fputcsv在csv中的十进制值后放置空格?

将值赋给变量并转换为字符串 例如:$test='14。31 '; $row[]=(string)$test;

或使用双引号

<?php
$fields[] = "case 1 - chr(32)";
$fields[] = "14.31 " . chr(32); // NO trailing space in .csv

$fields[] = "case 2 - chr(160)";
$fields[] = "14.31 " . chr(160); // 2 trailing spaces in .csv

$fields[] = "case 3 - rtrim + chr(32)";
$fields[] = rtrim("14.31 ", " ") . chr(32); // NO trailing space in .csv

$fields[] = "case 4 - rtrim + chr(160)";
$fields[] = rtrim("14.31 ", " ") . chr(160); // 1 trailing space in .csv

$fp = fopen('myfile.csv', 'w');

fputcsv($fp, $fields);

fclose($fp);
?>
