如何打开一个文本文件并用PHP appendstyle写入它
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);
要将数据附加到文件中,您需要以附加模式打开文件(请参阅 fopen):
  • ‘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.

所以在只写append模式下打开textFile.txt:

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

但您也可以使用将fopen,fwrite和fclose组合在一起的更简单的功能file_put_contents

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