Creating Files with PHP

Introduction:

Creating a new page in PHP is actually a lot easier than you think. Using a few simple functions and a form, you can create virtually any kind of file, assuming you have the correct permissions of course.

addfile.html:

<html>
<body>
<form action="addfile.php" method="post">
<p>File name - <input type="text" name="file_name" />
<p>
<p>File Extension:
<select name="file_ext">
<option value=".php">PHP</option>
<option value=".txt">Text</option>
<option value=".html">HTML</option>
<option value=".js">JavaScript</option>
</select>
</p>
<p>
<input type="submit" name="submit" value="Submit!" />
</p>
</body>
</html>

Explanation - addfile.html:

The addfile.html page is just a simple form that allows us to name the new page and select the extension. Pretty much self explanatory .

addfile.php:

[php]<?php

if(isset($_POST['submit'])) //has the form been submitted?

{

$file_directory = "/files/"; //the directory you want to store the new file in

$file_name = strip_tags($_POST['file_name']);//the file's name, stripped of any dangerous tags

$file_ext = strip_tags($_POST['file_ext']); //the file's extension, stripped of any dangerous tags

$file = $file_directory.$file_name.$file_ext; //this is the entire filename

$create_file = fopen($file, "w+"); //create the new file



if(!$create_file)

{

die("There was an error creating/opening the file! Make sure you have the correct permissions!\n");

}

$chmod = chmod($file, 0755); //set the appropriate permissions.

//attempt to set the permissions

if(!$chmod) 

{ 

echo("There was an error changing the permissions of the new file!\n"); //error changing the file's permissions

}

//attempt to write basic content to the file

if (fwrite($create_file, "Content goes here!") === FALSE) {

echo "Error writing to file: ($file)\n";

}

fclose($create_file);

echo "File was created successfully!\n"; //tell the user that the file has been created successfully

exit; //exit the script

}else{ //the form hasn't been submitted!

header("Location: addfile.html"); //redirect the user back to the add file page

exit; //exit the script

}



?>[/php]
