Question

我正在尝试编写一些PHP代码，它将$ _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
",""","""""",""""
",""",""""""
","""
"

如您所见，该程序在我的数据中添加了引号和逗号，我不想要。这显然是通过'file（“weather_data.csv”）来完成的，但我不知道如何禁用或解决这个问题。

这是我现在的代码：

<?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);

?>

Answer 1

$ fileContents读取为字符串数组，每行CSV文件一个条目，但不解析实际的CSV数据。最后一个fputcsv尝试将此数据写为CSV并将其转义（添加引号和内容）。您需要使用fwrite而不是fputcsv将旧文件内容（$ fileContents）添加到您的文件中：

fwrite($file, implode("\n", $fileContents));

php file（）函数创建引号和逗号
