PHP simply implements a method to generate txt files to a specified directory

The example in this article describes how to simply implement PHP to generate a txt file to a specified directory. Share it with everyone for your reference, the details are as follows:

<?php
//fopen第二个参数可以是以下四个,区别就是是清空内容再写还是在后面累加内容
//"w" 写入方式打开，将文件指针指向文件头并将文件大小截为零。如果文件不存在则尝试创建之。
//"w+" 读写方式打开，将文件指针指向文件头并将文件大小截为零。如果文件不存在则尝试创建之。
//"a" 写入方式打开，将文件指针指向文件末尾。如果文件不存在则尝试创建之。
//"a+" 读写方式打开，将文件指针指向文件末尾。如果文件不存在则尝试创建之。
$myfile = fopen("c:/newfile.txt", "a") or die("Unable to open file!");//这个是在c盘根目录生成文件
$txt = $_GET;//获取参数
$b="";
foreach($txt as $k=>$v){
  $b = $b ."[".$k."]=>".$v."\n";
}
$txt1 = $_POST;
foreach($txt1 as $k=>$v){
  $b = $b ."[".$k."]=>".$v."\n";
}
$b = $b."123";
fwrite($myfile, $b);//写入内容,可以写多次哦,不过没啥意义,因为你拼接好字符串,一次写入就行了
fclose($myfile);//关闭该操作
?>

A simple and useful method is

file_put_contents("c:/zll.txt","内容");
