I want be able to upload an image or just paste the URL of an image in order to upload it a sa profile picture for my website users.
the point is i dont wanna store the url but i want to have a copy of that image on my server because if that external image will be lost i dont want to lose it either...
i believe facebook and tumblr etc do so... what the php script or best practice to do that?
thanks!
You can get the contents (bytes) from the image using the PHP function (http://php.net/manual/en/function.file-get-contents.php)
$contents = file_get_contents('http://www.google.com/images/logos/ps_logo2.png');
You can use CURL library as well... Here's an example of how you can downloadImageFromUrl with and save it in a local SaveLocation
function downloadImageFromUrl($imageLinkURL, $saveLocationPath) {
$channel = curl_init();
$curl_setopt($channel, CURLOPT_URL, $imageLinkURL);
$curl_setopt($channel, CURLOPT_POST, 0);
$curl_setopt($channel, CURLOPT_RETURNTRANSFER, 1);
$fileBytes = curl_exec($channel);
curl_close($channel);
$fileWritter = fopen($saveLocationPath, 'w');
fwrite($fileWritter, $fileBytes);
fclose($fileWritter);
}
You can use this as follows:
downloadImageFromUrl("http://www.google.com/images/logos/ps_logo2.png", "/tmp/ps_logo2.png")
You can also get the same name of the image by parsing the URL as well...
I think this is you are looking for: Copy Image from Remote Server Over HTTP
You can use a function called imagecreatefromjpeg or something. It takes a URL path to the image and creates a new image off of that. Have a look at http://php.net/manual/en/function.imagecreatefromjpeg.php
There's different functions for different extensions, though (if you prefer using such). You may need to check for the image extension from the URL and use the appropriate function I suppose.
Handling uploads is covered in this documentation, and if users paste a URL, I'd recommend using file_get_contents to save a copy of the image to your server, and then you can simply store the path to that image, rather than the external image.

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 $largeimg variable.
So, I have a little PHP code that uses Kaywa to generate and display a QR code:
echo "<img src='http://qrcode.kaywa.com/img.php?s=10&d=$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.
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 have a picture url like this http://www.address.com/image.jpg
I want do dynamically save this image on my server
How can i achieve this using php
Thanks
You can get it using file_get_contents() and saving it using file_put_contents(). Something like:
$image = file_get_contents('http://www.address.com/image.jpg');
file_put_contents('image.jpg', $image);
You also might want look into cURL to fetch the image; it should perform better than file_get_contents() (unless you compile curl with --with-curlwrappers)
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.
