PHP

Question

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 returns $row['TOTAL'] 的数值格式为 (1523,45)。如何更改格式 (1.523,45)？我试过这个：$ret[] =[$row['JUDET'], number_format(floatval($row['TOTAL']),2,",",".")] 而不是 work.Thank 你！

Answer 1

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

执行 1.523,45

在你的情况下它将是

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

希望对您有所帮助
