php file()函数创建引号和逗号

我正在尝试编写一些php代码,将$_GET-data作为输入,并将其保存到csv文件中。 当多次运行代码时,我的csv文件如下所示:

Date,Time,Temperature,"Air Humidity","Soil Humidity",Light,"Wind Direction","Wind Speed",Rain
2013-03-16,16:24:27,12,80,40,82,255,10,0
"2013-03-16,16:24:26,12,80,40,82,255,10,0
","""2013-03-16,16:24:26,12,80,40,82,255,10,0
",""",""""""2013-03-16,16:24:25,12,80,40,82,255,10,0
",""","""""",""""
",""",""""""
","""
"

正如您所看到的,该程序在我不想要的数据中添加了引号和逗号。这显然是由“file(“weather_data.csv”)”完成的,但我不知道如何禁用或解决此问题。

这是我目前的代码:

<?php

// Save received data into variables:
$temperature  = $_GET["t"];
$airHumidity  = $_GET["ha"];
$soilHumidity = $_GET["hs"];
$light        = $_GET["l"];
$windDir      = $_GET["wd"];
$windSpeed    = $_GET["ws"];
$rain         = $_GET["r"];

// Arrays for the column descriptor (first line in the csv-file) and the recent data:
$columnDescriptor = array("Date","Time","Temperature","Air Humidity","Soil Humidity","Light","Wind Direction","Wind Speed","Rain");
$recentData       = array(date("Y-m-d"),date("H:i:s"),$temperature,$airHumidity,$soilHumidity,$light,$windDir,$windSpeed,$rain);

$fileContents = file("weather_data.csv");
array_shift($fileContents); // removes first field of $fileContents

$file = fopen("weather_data.csv","w");

fputcsv($file,$columnDescriptor);
fputcsv($file,$recentData);
fputcsv($file,$fileContents);

fclose($file);

?>
