Purely basic folder creation

纯粹的基本文件夹创建

<?php mkdir("testing"); ?><= this, actually creates a folder called "testing".

<?php mkdir("testing"); ?><= this，实际上创建了一个名为“testing”的文件夹。

• mkdir () function on PHP.net

• PHP.net 上的 mkdir() 函数

Basic file creation

基本文件创建

<?php
$file = fopen("test.txt","w");
echo fwrite($file,"Hello World. Testing!");
fclose($file);
?>

Use the aor a+switch to add/append to file.

使用a或a+开关添加/附加到文件。

• fwrite() function on PHP.net

• PHP.net 上的 fwrite() 函数

EDIT:

编辑：

This version will create a file and folder at the same time and show it on screen after.

此版本将同时创建一个文件和文件夹，然后将其显示在屏幕上。

<?php

// change the name below for the folder you want
$dir = "new_folder_name";

$file_to_write = 'test.txt';
$content_to_write = "The content";

if( is_dir($dir) === false )
{
    mkdir($dir);
}

$file = fopen($dir . '/' . $file_to_write,"w");

// a different way to write content into
// fwrite($file,"Hello World.");

fwrite($file, $content_to_write);

// closes the file
fclose($file);

// this will show the created file from the created folder on screen
include $dir . '/' . $file_to_write;

?>

You can create a directory with PHP using the mkdir()function.

您可以使用mkdir()函数使用 PHP 创建目录。

mkdir("/path/to/my/dir", 0700);

mkdir("/path/to/my/dir", 0700);

You can use fopen()to create a file inside that directory with the use of the mode w.

您可以使用fopen()使用 mode 在该目录中创建一个文件w。

fopen('myfile.txt', 'w');

fopen('myfile.txt', 'w');

w: Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

w: 只开放写；将文件指针放在文件的开头并将文件截断为零长度。如果该文件不存在，请尝试创建它。

在回答如何在 PHP 中写入文件的问题时，您可以使用以下示例：

    $fp = fopen ($filename, "a"); # a = append to the file. w = write to the file (create new if doesn't exist)
    if ($fp) {
        fwrite ($fp, $text); //$text is what you are writing to the file
        fclose ($fp);
        $writeSuccess = "Yes";
        #echo ("File written");
    }
    else {
    $writeSuccess = "No";
    #echo ("File was not written");
    }

... You can then use copy()to duplicate a PHP file, although this sounds incredibly inefficient.

... 然后您可以使用copy()复制 PHP 文件，尽管这听起来非常低效。
