So I'm making a notepad app in PHP, but I want to add the ability to share the file amongst your peers or something.
It's based on AJAX, and it saves the file automatically, and the file is named to what your IP address is after being hashed in md5.
What I want to do is maybe go to /view/837ec5754f503cfaaee0929fd48974e7, while the actual text file is located at /notes/837ec5754f503cfaaee0929fd48974e7.txt
I know I'll have to use file_get_contents(), but I don't know how to display it on a page.
I could just have it link to the .txt file, but I don't want it raw. I want it to have some style.
How would I go about doing this? Where can I start?
First you would need a way to store a variable in the URL (the file name). This can be easiest done using the querystring.
So the link to a file for your user to see would be '/view/?file=MYFILENAME'
This would then be interpreted by your php (this could also be wrapped in AJAXy goodness) into a path to retrieve the text file from.
view/index.php
//Fetch the file based on the get variable
//Note the relative path
$file = file_get_contents('../notes/'.$_GET['file'].'.txt');
//Print the file. You can also dress it up or wrap it in HTML tags
echo $file;
When displaying the text file, there is some built in functions that will help. Most notable nl2br() which takes the new line characters in a text file and makes them into html <br> tags.
More reading on the GET array can be found here

I know how to save the sent texts in 1 text file created beforehand. but I need some way to save each text in separate text files which are created automatically
The code below will save the text, which was provided by the user via GET parameter named param, to a new file with unique name in form of hash (something like 6cc50baac239a47e165a320d03c76731.txt).
<?php
$text = $_GET['param'];
file_put_contents(md5(uniqid(rand(), true)) . '.txt', $text);
You can use fopen to create a file, but before using that, read following PHP Manual to find which mode is suitable for your case. Have a look in A list of possible modes for fopen() using mode section:
php.net - fopen function
Be successful.
i am looking for something to edit my PDF files on my server and replace text / links within.
I can not modify the files as they are generated, therefore i need a script that will modify them after.
Check this:

You need to read the pdf file first and then change the text and Regenerate it again
I am trying to read multiple image files from a folder (.htaccess protected) and display in a HTML page using php readfile().
The problem is I can see only the first image is read and the next is not shown in the browser. The code is as below
<?php
$image1 = 'files/com_download\256\50\www\res\icon\android\icon-36-ldpi.png';
$image2 = 'files/com_download\256\50\www\res\icon\android\icon-48-mdpi.png';
$imginfo = getimagesize($image1);
header("Content-type: ".$imginfo['mime']);
readfile($image1);
$imginfo = getimagesize($image2);
header("Content-type: ".$imginfo['mime']);
readfile($image2);
?>
I could see the first image 'icon-36-ldpi.png' successfully read and displayed in the browser and the second image is not read and not displayed in the browser.
Am I missing something? Any advice please.
Sorry if I am doing stupid but the requirement is to read multiple image files and render in the browser like a grid view. I cannot use img tag because of security reasons.
You can't dump both images out at once. Why not make two images in your html so the browser makes two calls to your script. Then use a GET param to pass the filename you want to display.
---Edit---
Important Security Note
There is an attack vector which you open up when doing soething like this. Someone could easily view your source html and change the parameter to get your image script to output any file they want. They could even use "../../" to go up directories and search for well known files that exist. e.g. "../../../wp_config.php". Now the attacker has your wordpress database credentials. The correct way to prevent against this is to always validate the input parameter properly. For example, only output if the file name ends with ".jpg"
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($_GET["url"]); ?>
<script>
document.location=jwplayer('mp3player').config.file;
</script>
Though I've actually just noticed they change 5 digits of the URL on each page request, and the script above uses 2 page requests. One to get the URL and HTML source and another to try and download the file, meaning the URL has changed before the second request has started.
What Im trying to do is use PHP to scrape a website of a url I enter into a parameter.
I want the whole raw source code.. But thats not all..
I want it then saved into an html page, and onto the local server of the php script.
Is there a Easy Snippet for this? or can someone easily write me up a code?
For example
I want to scrape http://google.com
So for instance, mysite.com/scrape.php?url=http://google.com
I want it to save the front page of google into http://mysite.com/scraped/google.com.html
Here's a script that will save the contents of the specified url into a file named scraped.html:
if (isset($_GET['url'])):
$contents = file_get_contents($_GET['url']);
file_put_contents('scraped.html', $contents);
endif;
To use a url in the call to file_get_contents() you must enable allow_url_fopen in your php.ini file.
Of course this will only save the actual source of the requested url and not any other resources, such as images, scripts and stylesheets.
