Automatic download?

[Cragsterboy]

 

Hey,

 

ive just started getting into php, so yeh im a bit of a noob at the moment.

 

But i was wondering, is there a script which automatic downloads a file from another server to its own server ???

 

So like every twenty four hours (becuase the data i want to download updates every 24 hrs) it downloads the file to its server?

 

Ive had a look around but all im finding is scripts to force users to download which i dont want, so yeh if there is a script could you help me out with it?

 

Thanks,

What is the file you're going to "download"? You could use file_get_contents, and then file_put_contents.

The file i want to download is a txt file, but its in urlencode() so when it downloads i need it to decode it as well, so i will have to find a script to do that as well, i did find a decoder script earlier but lost, but il find ti again in a moment. Do you have any tips or tricks for decoding it?

 

K ive just done a quick script with the two things you suggested, im guessing its wrong

 

<?php
echo file_get_contents("www.test.com/test.txt");
echo file_put_contents("test.txt","www.test.com/test.txt");

?> 

 

Am i on the correct lines there?

No, your code needs to be

<?php

$contents = file_get_contents("http://www.test.com/test.txt");
if(!empty($contents))
{
    file_put_contents("test.txt", $contents);
}

?>

 

The file i want to download is a txt file, but its in urlencode() so when it downloads i need it to decode it as well

Do you mean it encoded using urlencode()? If so PHP has built function called urldecode() to decode the urlencode'd string.

[Cragsterboy]

<?php

$contents = file_get_contents("http://www.test.com/test.txt");
if(!empty($contents))

$a = explode('&', $QUERY_STRING);

foreach($a as $key => $b)
{
   $b = split('=', $b);
   echo 'Value for parameter '.htmlspecialchars(urldecode($b[0])).' is '.htmlspecialchars(urldecode($b[1]))."<br />\n";
} 

{
    file_put_contents("test.txt", $contents);
}

?>

 

Ok ive added the code to decode the urlencode(), im guessing again that code above is wrong lol as you can see iam a bit of a noob with php lol SO yeh sorry for the annoyance lol

WHat that! What's supposed to be encoded? The file url or the contents of the file? If its the contents of the file then its

<?php

$contents = file_get_contents("http://www.test.com/test.txt");
if(!empty($contents))
{
    $contents = urldecode($contents);
    file_put_contents("test.txt", $contents);
}

?>

What's that?  urldecode() is the opposite of urlencode()...what were you trying to do?

 

Oh, wildteen beat me to it. D:

Lol that made me laugh, see told you i was wrong (a large amount wrong) I was reading the link you gave me and it said that the code i put in was the right code and more cleaned up so i guess i was wrong lol.

 

Ok right im guessing now i need to do a cron job? So that it executes this script daily? Am i correct there? for once? lol

Yes.

[Cragsterboy]

whay go me.

 

Right i just used the script and it worked, except it didnt decode the text, so i change the chmods on it to 777, because i thoguht it was due to it not being able to execute and now my script wont work  ??? ive changed the chmods back and still no luck heres my script below

 

<title>Auto download</title>

<?php

$contents = file_get_contents("http://en8.tribalwars.net/map/tribe.txt");
if(!empty($contents))
{
    $contents = urldecode($contents);
    file_put_contents("world8.txt", $contents);
}

?>

 

ok now its showing this

 

The server encountered an unexpected condition which prevented it from fulfilling the request.

The script had an error or it did not produce any output. If there was an error, you should be able to see it in the error log.

 

What am i doing wrong now? lol

Check your servers error log, the reason for the error will be logged there.

 

Also you'll need to make sure the file world8.txt has write permissions (chmod 755 should do it). I am also amusing you're running php5, as file_put_contents is only available for PHP5. You can check the version of PHP by running phpversion() function.

yeh i got php 5 and ive chmoded the fiel to that

 

So whats gone wrong ???

i'd recommend using a php function called system for any serious downloads ie

 

<?php

 

//auto

 

system('wget https://example.com/auto.zip', @$foo);

if(system('unzip -r auto.zip', @$foo)) echo "downloaded"

[Cragsterboy]

 

right by some luck ive got it to work 

 

But its not decoding the text from urlencode(), so looks like im going to investigate how to do that, anybody suggest any other codes to do this?

Sorry for the double post but i have fixed the error, seems like the code

 

if(!empty($contents))

 

was confusing it so i removed that and now it decodes it fine! Thanks for the help!
