PHP - 更改数字格式 [英] PHP - change number format

问题描述

我有这个代码:

<?php
if(isset($_POST['get_luna_inceput'])){
  $ret =[];
  $sch_luna_inceput = $_POST['get_luna_inceput'];
  $sql = "SELECT
            ...";
  $result = $conn->query($sql);
  if ($result->num_rows > 0){
  while($row = $result->fetch_assoc()){
    $ret[] =[$row['JUDET'], floatval($row['TOTAL'])];
  }
  }
}
  echo json_encode($ret) ;
?>

我的代码 sql 以数字格式 (1523,45) 返回 $row['TOTAL'] 的值.如何更改格式 (1.523,45)?我试过这个: $ret[] =[$row['JUDET'], number_format(floatval($row['TOTAL']),2,",",".")] 和不行.谢谢！

My code sql returns values for $row['TOTAL'] in number format (1523,45). How can I change in format (1.523,45)? I tried this: $ret[] =[$row['JUDET'], number_format(floatval($row['TOTAL']),2,",",".")] and not work.Thank you!

推荐答案

$num = 1523.45;
echo number_format ( $num, 2, ",", "." );

执行 1.523,45

executes 1.523,45

在你的情况下是

$ret[] = [ $row['JUDET'], number_format( $row['TOTAL']), 2, ",", ".") ];
