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.

I have a question. I would like to add rotating links inside my email signature to
track results on my site. I can make these dynamic tracking urls on google as you may know
but I would like to rotate them inside my email signature to see which text draws the most
conversions or returning visitors.
Is this possible?
I found this for instance:
$mybanners[1] = '<img src="banner1.jpg">';
$mybanners[2] = '<img src="banner1.jpg">';
$id = rand(1,2);
echo $mybanners[$id];
But when I look into my windows live mail I can only upload html files.
Does someone know how to do this?
You can't provide PHP scripts in a mail, since it is a server-side language and it will be opened by a mail client. Even Javascript is very often blocked for security reason.
What you can do is make a "fake" image which will be in fact generate by a PHP script. YOu can find inspiration by looking to script made for forum avatar rotation. The idea is to generate an image, which will be displayed to the client but, in the same time, save some data about the user who requests the image if you want:
<?php
// Save whatever you want about the user
file_put_content("log/user.txt", $_SERVER['HTTP_REFERER']);
// Render a valid PNG image
header('Content-Type: image/png');
readfile("/path/to/banner.png");
?>
This script should be used as a standard image (with, if you want, a nice URL rewrite to make a .png link):
<img src="http://www.example.com/my_super_banner.php" />
where my_super_banner.php is the script described before.
I have a question about displaying images in PHP. I need to have a PHP file display as JUST an image, as opposed to an image embedded in a web page, as if you had browsed to the JPEG image directly. The reason that I need it to be a PHP page as opposed to actually browsing to the image is that I need to resize the image before it is delivered. It would be easiest to use an image directly because that way I can display the image in a desktop application more easily. Is there any way to do this? Thanks!
<?php
header('Content-Type: image/jpeg');
readfile('path/to/image.jpeg');
You need to set the header Content-Type property to be the correct image type. See this link for the some examples.
http://www.electrictoolbox.com/image-headers-php/
Choose the correct header :
header("Content-type: image/png");
And use php gd to change the image size : http://php.net/manual/fr/book.image.php
I am done with generating PDF file using FPDF in php. But the problem is how to open this pdf without the Save As option? I want to display the pdf document in the browser.
http://www.fpdf.org/en/doc/output.htm
Syntax: Output([string name] , string dest) , use I as Destination and fdpf will try to show it in the browser, if browser plugings and so on enable it
You cannot force this display, as it is up to the user to choose to display the PDF inline or systematically save them. I prefer the second option...
Now, there is a JavaScript / HTML 5 project (experimental!) to display PDF without plugin, so perhaps you can try that.
Even when using fpdf passing the output to the browser, I believe its still up to the user if they open or save it.
A solution would be to use some kind of PDF viewer, for example http://view.samurajdata.se/
Try this $pdf->Output('I', 'filename.pdf')
See the reference http://www.fpdf.org/en/doc/output.htm
Set header's content-type to 'application/pdf'. Then, most browsers will try to open it and show in-browser (or at least ask user to save or open file)
Your browser must have pdf plugin installed. If you havent done so install latest version of Acrobat Reader. If you are using fpdf, output the string instead of forcing download
For details
http://www.fpdf.org/en/doc/output.htm
Try echoing the PDF instead to using header function. The header function will force the browser to download. The echo 'might' show the pdf.
I'm a beginner here and need help. I have this code, which works and outputs a graph in my browser (if this is the only code in php file). I don't know how to add text below or above just like any other site. When I try, it returns my whole code in the browser. How do I go on about this?
<?php
// content="text/plain; charset=utf-8"
require_once ('jpgraph/src/jpgraph.php');
require_once ('jpgraph/src/jpgraph_line.php');
// Some data
$ydata = array(11,3,8,12,5,1,9,8,5,7);
// Create the graph. These two calls are always required
$graph = new Graph(350,250);
$graph->SetScale('textlin');
// Create the linear plot
$lineplot=new LinePlot($ydata);
$lineplot->SetColor('blue');
// Add the plot to the graph
$graph->Add($lineplot);
// Display the graph
$graph->Stroke();
?>
Thanks in advance!
What you need is quite simply:
<img src="graph.php">
Put that in a separate HTML file or PHP script. You cannot output the image and text in the same script / web page. It needs to be separated.
Don't worry about the .php extension for the image src= attribute. It will display despite the lack of .jpeg extension. (The Graph class already outputs the correct MIME type I assume.)
I'm a bit rusty on PHP, but I believe that all "require" are supposed to be made before any content is output. Otherwise, the normal HTML/XHTML syntax and formatting take precedence.
I haven't actually used this library, but I'm assuming the image is output directly to the browser. It's probably easiest to create a new HTML document (or whatever the rest of your site is powered by) and include this as an image, with the image's src being the name of this script.
I would like to generate a dynamic image from a script, and then have it load to the browser without being persistent on the server.
However, I cannot call this by setting the image's src="script.php", since that would require running the script that just generated the page and its data all over again, just to get the final data that will generate the graph.
Is there a way to do this that is similar to setting image's src="script.php", but which is called from within another script, and just sends the image without saving it? I need access to the data that is used in the generation of the markup, in order to create this dynamic image.
Or, if not, what is the easiest way to destroy the image once the page is loaded? a quick ajax call?
Is there any way to cache certain data for some limited time frame in order for it to be available to some other script?
Any ideas would be greatly appreciated, as I'm having a really hard time finding the right solution to this...
Thanks!
You can inline the image into a <img> tag if you need to.
Like
<?php
$final_image_data; // Your image data, generated by GD
$base64_data = base64_encode($final_image_data);
echo "<img src=\"data:image/png;base64,{$base64_data}\" ... />";
?>
That should work on all modern browsers, and IE8. Doesn't work well with some email clients tho (Outlook, for one).
Also, another solution I found is to store the image in a session variable which is then called from a php script in the image tag. This would allow a user specific image to be served, and then removed from memory by the script... This also avoids messy img src="" tags...
Hopefully that is helpful to someone.
Use a rewrite rule.
RewriteRule ^magicimage.jpg$ /myscript.php
Then simply echo your image data from gd, instead of writing it to disk -- which is as simple as not providing a filename to the appropriate image*() function
myscript.php
<?php
$im = imagecreatetruecolor($w, $h);
//...do gd stuff...
header('Content-type: image/jpeg');
//this outputs the content directly to the browser
//without creating a temporary file or anything
imagejpeg($im);
And finally, utilize the above
display.php
<img src="magicimage.jpg">
