How do you open a textfile and write to it with php appendstyle

    textFile.txt

        //caught these variables
        $var1 = $_POST['string1'];
        $var2 = $_POST['string2'];
        $var3 = $_POST['string3'];

    $handle = fopen("textFile.txt", "w");
    fwrite = ("%s %s %s\n", $var1, $var2, $var3, handle);//not the way to append to textfile
fclose($handle);

推荐答案

要将数据追加到文件中，您需要以追加模式打开文件(请参见

To append data to a file you would need to open the file in the append mode (see fopen):

• 'a'
  仅开放写作；将文件指针放在文件末尾.如果文件不存在，请尝试创建它.
• 'a +'
  开放供阅读和写作；将文件指针放在文件末尾.如果文件不存在，请尝试创建它.

• 'a'
  Open for writing only; place the file pointer at the end of the file. If the file does not exist, attempt to create it.
• 'a+'
  Open for reading and writing; place the file pointer at the end of the file. If the file does not exist, attempt to create it.

因此要在仅写入附加模式下打开 textFile.txt :

fopen("textFile.txt", "a")

但是您也可以使用更简单的功能 file_put_contents ，该功能结合了fopen，fwrite和fclose的一项功能:

But you can also use the simpler function file_put_contents that combines fopen, fwrite and fclose in one function:

$data = sprintf("%s %s %s\n", $var1, $var2, $var3);
file_put_contents('textFile.txt', $data, FILE_APPEND);
