So, I have a little PHP code that uses Kaywa to generate and display a QR code:
echo "<img src='http://qrcode.kaywa.com/img.php?s=10&d=$qr_url' alt='QR code' />";
Easy peasy. But for the sake of having a backup, I'd like to save this image to my server, maybe in "myserver/qrbackups". I know how to make PHP upload a file from a form, but can I do from a retrieved image URL?
See file_get_contents.
$data = file_get_contents("http://qrcode.kaywa.com/img.php?s=10&d=$qr_url");
$saved = file_put_contents('/path/to/myserver/qrbackups/the-code.png', $data);
Keep in mind /path/to/myserver/qrbackups/the-code.png should be a unique file name for each individual QR code.
You can use cURL to programmatically access URLs.
http://us3.php.net/manual/en/curl.examples-basic.php
You can try to use curl or file_get_contents to pull the file from the server.
For example:
http://www.phpriot.com/articles/download-with-curl-and-php
And after getting the file just display the one you got from your server or remote.
copy('http://domain.com/path', '/tmp/file.jpeg');
should work for you. And, as others have pointed you, cURL will work too.
If you have the GD extension on your server, you can use a library like PHP QR Code to eliminate the dependency on Kaywa. Usage requires only one line of code wherever you want to generate a QR code.

I am trying to save to disk an image that is served to me via a JSON result. The returned JSON result property that I am interested in is this:
https://i.scdn.co/image/6cd03f58ddf30a1393f06d6469973ba16ac908df
Which is the correct image. The problem is that, while the above URL does display the image, it does not allow me to download it, yet I can download it by right-clicking on it.
What I need to be able to do is, using my PHP code, save it to disk.
I have no issues saving results from other sites that give results that link to a direct image extension (.jpg, .gif or .png). But I have not been able to figure out how to programmatically download the image from the above URL.
Is it possible?
This is the code that I use, which works correctly on results that give a URL that has a correct image extension. The URL returned is loaded into the $largeimg variable.
$input = $largeimg;
$output = 'image.jpg';
file_put_contents($output, file_get_contents($input));
How do I achieve this?
file_get_contents() is able to accept raw URI arguments. Your code works perfectly for me, if modified in the way:
$input = 'https://i.scdn.co/image/6cd03f58ddf30a1393f06d6469973ba16ac908df';
So, file_get_contents() can download the image directly. I think, the problem is your $largeimg variable.
So this is simple to understand what i want to achieve. So i get links like theese:
http://rockdizfile.com/atfmzkm7236t
http://rockdizfile.com/xuj5oincoqmy
http://rockdizfile.com/pg8wg9ej3pou
So theese links are from one cloud storage site I want to make a php script that automates their downloading.
So I can't find which is the script or the thing these links download button starts and how can I start that so i can download it with php on my server?
Basically my idea is to download a lot of files but don't wanna do it manually so need automatic way of doing it. As far as I know I make a request which is the following 2 urls:
http://rockdizfile.com/pg8wg9ej3pou
http://wi32.rockdizfile.com/d/wsli6rbhfp4r2ge4t7cqeeztijrprelfiw4afvqg5iwspmvqabpkmgiz/Desislava%20feat.%20Mandi%20&%20Ustata%20-%20Pusni%20go%20pak%20(CDRIP).mp3
So the first url is executing the next one but here comes the tricky part as far as I tested that last string Desislava%20feat.%20Mandi%20&%20Ustata%20-%20Pusni%20go%20pak%20(CDRIP).mp3 is the file name we get when downloading so if you change it with for example somefile.mp3 it will download somefile.mp3 but with the same file content as http://wi32.rockdizfile.com/d/wsli6rbhfp4r2ge4t7cqeeztijrprelfiw4afvqg5iwspmvqabpkmgiz/Desislava%20feat.%20Mandi%20&%20Ustata%20-%20Pusni%20go%20pak%20(CDRIP).mp3 so the data is hidden in this hash wsli6rbhfp4r2ge4t7cqeeztijrprelfiw4afvqg5iwspmvqabpkmgiz or i think so. And now is the tricky part how to get this hash? we have almost everything we have the code for the url atfmzkm7236t the hash wsli6rbhfp4r2ge4t7cqeeztijrprelfiw4afvqg5iwspmvqabpkmgiz and the filename Desislava%20feat.%20Mandi%20&%20Ustata%20-%20Pusni%20go%20pak%20(CDRIP).mp3 There must be a way to download from this site without clicking so please help me kinda a hack this :)
you can use PHP's header function to force a file to download
header('Content-disposition: attachment; filename=index.php');
readfile('Link');
You should know that this will not give you the ability to download PHP files from external websites.
You can only use this if you got the direct link to a file
It's impossibly to tell you without the source code
e.g. sha1("Test Message") gives you 35ee8386410d41d14b3f779fc95f4695f4851682 but sha256("Vote this up") gives you 65e03c456bcc3d71dde6b28d441f5a933f6f0eaf6222e578612f2982759378ed
totally different... unless you're hidden function add's "65e03c456bcc3d71dde6b28dxxxxxxxxxxxxxxxxxxxxxxxxxx" (where xxxxxxxxxxxxxxxxxxxxxxxxxx is a bunch of numbers I can't be arsed to work out) to each hash...
then sha1("Test Message") gives you 65e03c456bcc3d71dde6b28d441f5a933f6f0eaf6222e578612f2982759378ed
The file is embedded into the swf player.
alert(jwplayer('mp3player').config.file);
Something like:
<?PHP echo file_get_contents($_GET["url"]); ?>
<script>
document.location=jwplayer('mp3player').config.file;
</script>
Though I've actually just noticed they change 5 digits of the URL on each page request, and the script above uses 2 page requests. One to get the URL and HTML source and another to try and download the file, meaning the URL has changed before the second request has started.
What are some possible ways to save an image or make use of it that is generated from a PHP script. Using save as it does not help though.
This is not an image created by me that's why I want to avoid get_contents.
here is the picture
and here is the url
https://render01.fontshop.com/fonts/font_rend.php?idt=f&id=38005&rbe=fsifr&rt=how+do+I+save+this?&rs=38&w=500&bg=ffffff&fg=000000&tp=0.0
Just write the content of the URL to a file
<?php
file_put_contents("img.png", file_get_contents("http://render01.fontshop.com/fonts/font_rend.php?idt=f&id=38005&rbe=fsifr&rt=how+do+I+save+this?&rs=38&w=500&bg=ffffff&fg=000000&tp=0.0"));
Using file_put_contents() function. If you don't have data in variable and want to readout use file_get_contents()
Since you are not generating the image in your own code, the simplest would be a combo of file_get_contents and file_put_contents:
$url = '...'; // your url here
$data = file_get_conents($url);
file_put_conents('image.png', $data);
In this specific case the render is a PNG image, but if there's a possibility of it being a JPEG or something else then you need to somehow detect that as well. I 'm not giving any suggestions for this because there's not enough info to go by.
You can define a filename in imgpng() or the other functions to tell PHP to store the picture instead of sending it to the calling browser.
I understand you want to save it on the client, with a browser, not on the server.
"Save as" worked fine for me (Firefox 7). In Chrome you'll have to specify the extension of the filename manually. Did not test other browsers, but it should work similarly
You can do this from the terminal using the curl command.
curl -o out.png 'http://render01.fontshop.com/fonts/font_rend.php?idt=f&id=38005&rbe=fsifr&rt=how+do+I+save+this?&rs=38&w=500&bg=ffffff&fg=000000&tp=0.0'
This will save the file as out.png
use imagepng function.
It will return file to browser or save it specified location.
Need to set parameter for function to save image on specified location.
I'm writing a web app that at one point allows a user to upload a photo to a flickr account (mine). I want to do this without saving the intermediate image on the server my web app is on.
What I've got so far is a page which implements phpFlickr and accepts a POST from a simple html form. I use $_FILES['file']['tmp_name'] as the path for phpFlickr to use. Here's the code:
<?php
require_once("phpFlickr.php");
$f = new phpFlickr("apikey", "secret", true);
$_SESSION['phpFlickr_auth_redirect'] = "post_upload.php";
$myPerms = $f->auth("write");
$token = $f->auth_checkToken();
$phid = $f->sync_upload($_FILES['file']['tmp_name']);
echo "Uploading Photo..." . $phid;
?>
I'm guessing that the tmp file is being lost because of the redirect that happens when $f->auth("write") is called, but I don't know. Is there a way to preserve it? Is there any way to do this without saving the file to the server?
Answer: There is No way to directly upload a file to Flickr without saving it as an intermediate file.
I've moved on to using move_uploaded_file() followed by a flickr API call, and its working perfectly.
I've also managed to get it to play nice with the excellent Jquery Uploadify, which lets me send multiple files to it in one go.
is that possible to show whole php page as an image file like png or jpg ?
for example,
<img src="details.php?id=44">
just like a screenshot of the page.
Thx
<?
// details.php file
// {
// do stuff to create your image and store in $my_image
// }
header("Content-type: image/jpg");
echo $my_image;
?>
1) output the mime type in the header.
2) echo your binary data
easy!
Not in the way you're thinking. You can use the PHP ImageMagick library or the PHP GD Library to generate an image dynamically and output it, but in order to get screenshots of a page you'll really need an outside service.
it depends on what you want to show. if its html/js/css, it varies across browsers.
If its unicode text to be displayed as images, you can use GD library for the purpose
I think you are talking about taking screenshots of a url or webpage. You can you freely available like:
http://www.shrinktheweb.com/
http://picoshot.com/
There are many such freely available services. If you want to host such service on your own server. You will need to create a software which can open your browser and take screenshot of the url. Ther are some softwares available as well. I hope it helps.
