Creating a File & Downloading It Using PHP
In this PHP coding tutorial, you will learn how to create a file using PHP, and then enable your users to download it. The tutorial will teach you how to get a user’s ip, place it in a text file, and have the ‘download it all’ without the text file being stored on your server for more than a few seconds.
Today
I’ll show you how to get a user’s ip, stick it in a text file, and have
the download it all without the text file being stored on your server
for more than a few seconds.
Step 1: Getting the I.P Address
To get the ip address, we use this code:
So when we put it as a varible:
Step 2: Creating the file
Now that we have the user’s ip address stored in a varible, we want to put it in a file.
So first, we need to create the file:
If you notice, we are using hte person’s ip address for the file name.
Now here is the final piece of that code:
Step 3: Writing to the file
So we have the file created and now we need to write to it. Use this code to do so:
Note that it writing the ip address to our file
Step 4: Close it
Not much for this:
Step 5: Forcing it
Now that we have the file created and with the ip adress in it, we have to make the browser be “forced” into downloading it
I’ll explain all that in a later tutiral.
Step 6: Deleting the file
To delete the file, all we need to do is this:
Note that it deletes the file named after that ip adress
Final Code
Final Thoughts
To make the file download as a text file, you’ll need to stick an txt extension on the ip adress. I used this code to do so:
Also, its not secure, so I would clean it up before using it
All the best!
Step 1: Getting the I.P Address
To get the ip address, we use this code:
$_SERVER['REMOTE_ADDR'];So when we put it as a varible:
$ip = $_SERVER['REMOTE_ADDR'];Step 2: Creating the file
Now that we have the user’s ip address stored in a varible, we want to put it in a file.
So first, we need to create the file:
fopen($ip, 'w') or die("die");If you notice, we are using hte person’s ip address for the file name.
Now here is the final piece of that code:
$file = fopen($ip, 'w') or die("die");Step 3: Writing to the file
So we have the file created and now we need to write to it. Use this code to do so:
fwrite($file, $ip);Note that it writing the ip address to our file
Step 4: Close it
Not much for this:
fclose($file); Step 5: Forcing it
Now that we have the file created and with the ip adress in it, we have to make the browser be “forced” into downloading it
$filepath = "/home/manywor/public_html/phptest/";$file = $filepath . $ip; header("Content-type: application/force-download"); header("Content-Transfer-Encoding: Binary"); header("Content-length: ".filesize($file)); header("Content-disposition: attachment;filename=\"".basename($file)."\""); readfile($file); I’ll explain all that in a later tutiral.
Step 6: Deleting the file
To delete the file, all we need to do is this:
unlink($ip);Note that it deletes the file named after that ip adress
Final Code
//Get the IP Address of the user $ip = $_SERVER['REMOTE_ADDR']; //Create and close the text file $file = fopen($ip, 'w') or die("die"); //Write to the text file fwrite($file, $string); //Close it fclose($file); //Force it $filepath = "/home/manywor/public_html/phptest/"; $file = $filepath . $ip; header("Content-type: application/force-download"); header("Content-Transfer-Encoding: Binary"); header("Content-length: ".filesize($file));
header("Content-disposition: attachment;
filename=\"".basename($file)."\""); readfile($file); //Delete it unlink($ip);Final Thoughts
To make the file download as a text file, you’ll need to stick an txt extension on the ip adress. I used this code to do so:
//Replace the dots in it $ip =str_replace(".","",$ip); //Turn the IP into a text extention $extiontion = ".txt"; $ip = $ip .''. $extiontion;Also, its not secure, so I would clean it up before using it
All the best!
