So I found the perfect example of a page I would like to download images from, this so happens to be http://www.habbo.com/habbo-imaging/avatarimage?figure=ch-215-110.hd-180-7.lg-275-110.hr-893-61&direction=3&head_direction=3&headonly=1&gesture=sml&size=1
Now, when you go to save the image if you were to on your desktop, it reads as a PNG file, although I am trying to save it using PHP but I want it to save as GIF.
What I've so far is:
$ch = curl_init('https://www.habbo.com/habbo-imaging/avatarimage?figure=hr-125&direction=3&head_direction=3&headonly=1&gesture=sml&size=1');
$fp = fopen('game/c_images/badges/' . $badge_id . '.gif', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
I managed to get the permissions working and a image saves, but it's saving just the file name and the photo isn't there. So I'm guessing it has something to do with me saving a PNG file as a GIF, surely there's something I'm missing.
yes,You can save image using html dom.
like use
`$new_image_name = '2018_'.mt_rand();
$base_url = 'https://www.habbo.com/habbo-imaging/avatarimage?figure=hr-125&direction=3&head_direction=3&headonly=1&gesture=sml&size=1';
$img = "./image_path/$new_image_name.jpg";
file_put_contents($img,file($base_url));
$local_image_url = "http://example.org/test/path_to_image/$new_image_name.jpg";`

I am writing a script where I am just resizing images from the requested image url and caching them. I am also giving width & height as optional params for the request. I am caching the images by their filenames & I want to cover one use case when user requests the same image with different width or height.
Since I am using Codeigniter's image resizing library, the filenames are appended with _thumb. That's how I am storing the images.
What should I do in that case? One solution would be to check the md5 hash of the resized image and cached image.
Here's what I am thinking to do:
$ch = curl_init($url); //initialize cURL
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
$dataToWrite = curl_exec($ch); //Execute the given cURL session.
curl_close ($ch); //close the given cURL session
$fp = fopen($dirPath.$filename,'w');
fwrite($fp, $dataToWrite);
fclose($fp);
Finally,
if (md5_file($dirPath.$filename) == md5_file($dirPath.$resizedImage){
serveimagefromcache() & deletethedownloadedfile();
} else {
resizetheimage() && serveit();
}
I am concerned about the performance as well, I would appreciate any other suggestions.
Even though #arkascha's suggestion was quite good but saving the file as filename hash is much more better.
With this,
$ext = pathinfo($filename, PATHINFO_EXTENSION);
$filehash = sha1($filename.$width.$height);
$filename = $filehash.".".$ext
you can prevent the issue that I was having.
i want to download image from this url
http://feelgrafix.com/959413-rococo.html
and this the source image
http://feelgrafix.com/data_images/out/28/959413-rococo.jpg
but when i download image from this source
file Download page url not download source image
this the code i used it
$url = 'http://feelgrafix.com/data_images/out/28/959413-rococo.jpg';
$ch = curl_init($imgURL);
$fp = fopen('image.gif', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
curl_close($ch);
fclose($fp);
and this Other way
$content = file_get_contents($url); file_put_contents('sadsdasd.jpg',$content);
i think that this the protect from server ..
no one can download OR see the image direct before open the page home
so what can i do ?
Instead of using curl function i recommend you to user file_get_content($url) to fetch the file and file_put_contents($path) to save it in your desired path and in case if any error it throws just usin # before both the function.
I am using Google Charts from a URL for example:
http://chart.apis.google.com/chart?cht=lc&chs=250x100&chds=0,20...
How do I go about using PHP to save the image. I have tried:
$image = file_get_contents($lineChart->getUrl());
file_put_contents('playerchart.png', $image);
and
$ch = curl_init($lineChart->getUrl());
$fp = fopen('playerchart.png', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
However, both seem to corrupt the image and the image ends up not working.
Any ideas? Thanks
I tested the following code and I got a proper PNG that I could open in Preview.
$image = file_get_contents('http://chart.apis.google.com/chart?cht=lc&chs=250x10
0&chds=0,20');
file_put_contents('playerchart.png', $image);
Given that the above works, I would say that there is fair chance that there is an issue with the $lineChart->getURL() and it might not be returning exactly what you expect. (I'd say print it out to the screen and double check, there might be some other characters or which space or the like in there. The 'image' that you are saving to disk might actually be the HTML for a 404 page!)
If you'd like an alternative way of saving the file, I would suggest the below. This will fail if the destination URL is not an image.
$im = imagecreatefrompng($theurl);
imagepng ($im, 'mypic.png');
imagedestroy($im);
This works for me:
<?php
$img = file_get_contents("http://chart.apis.google.com/chart?cht=lc&chs=250x100&chds=0,20");
file_put_contents("test.png", $img);
?>
I'm willing to use thumbnails into my website which is mainly like websites directory.
I've been thinking to save url thumbnails into certain directory !
Example :-
I'm going to use free websites thumbnails service that gives me code to show thumbnail image of any URL as follow
<img src='http://thumbnails_provider.com/code=MY_ID&url=ANY_SITE.COM'/>
This would show the thumbnail of ANY_SITE.COM
i want to save the generate thumbnail image into certain directory my_site.com/thumbnails
Why i'm doing this ?
in fact my database table is like my_table {id,url,image} where i'm going to give the image thumbnail random name and store its new name into my_table related to its url then i can call it back anytime and i know how to do it but i don't know how to save it into certain directory.
any help ~thanks
Using cURL should work for you:
$file = 'the URL';
$ch = curl_init ($file);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
$rawdata=curl_exec($ch);
curl_close ($ch);
$fullpath = 'path to destination';
$fp = fopen($fullpath);
fwrite($fp, $rawdata);
fclose($fp);
You could use curl to fetch the remote image. You can save it with curl_setopt($handler, CURLOPT_FILE, '/my/image/path/here.jpg');. The id could be something simple like a hash of the original URL. Obviously you'd have to check to make sure the directories exist before you save the file (using is_dir() and creating them with mkdir() if they don't).
The following code retrieves an image and saves it to a local folder. A jpg file is indeed saved to local disk, with around 40KB filesize (seems correct). When I put the local path in an img tag, the file does not display.
Firebug > Inspect Element shows a size of 0 X 0 and I'm unable to view the image when saved to my desktop.
file_put_contents, file_get_contents and getimagesize don't return FAILs. $url IS a valid image. The problem is just saving it locally, the file seems to be corrupt - how come?
$url = $image->request_url; //the image generated on the remote server
//print_r(getimagesize($url)); die;
$img = 'thumbalizr/cache/screenshot_' . $row['id'] . '.jpg'; //path to our local cache folder + unique filename
if( !$captured_file = file_get_contents($url) ) die('file could not be retrieved');
elseif( !file_put_contents($img, $captured_file, FILE_APPEND) ) die('file could not be written to local disk'); //write the image to our local cache
"Are you sure the path is correct? Have you tried an absolute path?" YES
"Have you checked that the image is downloaded correctly, perhaps with another utility (e.g. ftp, diff)?" I can download the img via ftp but it does not open on my local computer either.
"What do you get if you call the URL directly in the browser?" FF just prints out the URL instead of showing the image
"Why are you using FILE_APPEND? if the target already exists, this writes to the end, which will naturally give you a corrupt image" I removed FILE_APPEND, no difference
"source and final extension are the same?" Yes I tried with jpg, jpeg and png - no difference
"First of all, example code is wrong. Can't use $capture_file in file_put_content because that variable is not defied becouso of if else if block logic." - WRONG, that code does run!
"Can you look into the image file" - no! Although the file has a realistic file size and I can download it, it's impossible to open it.
First off check the files you're been downloading in a text editor to see if you're getting HTML error pages instead of binary image data.
Second, I would use curl for this as it provides better success/error information. Here's your example modified to use it.
//path to our local cache folder + unique filename
$img_path = 'thumbalizr/cache/screenshot_' . $row['id'] . '.jpg';
$c = curl_init();
curl_setopt($c, CURLOPT_URL, $image->request_url);
curl_setopt($c, CURLOPT_HEADER, 0);
curl_setopt($c, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($c, CURLOPT_AUTOREFERER, true);
curl_setopt($c, CURLOPT_BINARYTRANSFER, true);
curl_setopt($c, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($c, CURLOPT_FORBID_REUSE, true);
// curl can automatically write the file out for you
curl_setopt($c, CURLOPT_FILE, $img_path);
// You can get more elaborate success/error info from
// curl_getinfo() http://www.php.net/manual/en/function.curl-getinfo.php
if (!curl_exec($c)) {
die('file could not be retrieved');
}
