i want to open a notepad from php file and the notepad should contain the text which i declare as string in php file. essentially a notepad should open with the text I pass from php file.
If the PHP file is executing on a web server you cannot cause a web browser to open a new process like that. I'm sure you can imagine what a security hole that would be!
If you're running a PHP file as a local script in CLI mode, you should be able to launch notepad like any other process, e.g. using backticks or exec etc.
However, if you really wanted to do this server side, the best you could do is have a PHP script which used a Content-Disposition header, e.g.
//tell client we're delivering text
header('Content-type: text/plain');
//hint that it's a downloadable file
header('Content-Disposition: attachment; filename="textfile.txt"');
//output our text
echo "The quick brown\nfox jumps over\nthe lazy dog.";
The user can then save this file and open in their editor of choice.
You can't get PHP to open a window on the user's machine, because PHP is run entirely on the server. By the time the output reaches the browser the script will generally have terminated - you can only do what you can ask the browser to do and what it will let you (using HTML / headers etc.). For security purposes the browser will not (or should not) let an arbitrary website do very much with your machine - e.g. it will not let you spawn new Windows processes.
The best I think you could do is something like this:
$string = 'a string';
header('Content-type: text/plain');
header('Content-Disposition: attachment; filename="file.txt"');
echo $string;
This will send the relevant headers so that the browser will treat the content as a download called file.txt of type plain text. The browser should prompt them to download a file which will be likely to open in notepad, unless they have changed the file association for .txt .
However you won't be able to get any changes back that the user makes to the document unless you ask them to upload it, so I'm not sure this is a good solution to what you are trying to acheive.
It is possible to execute a program from php but only server-side.
So imagine the server runs Windows, it would start notepad server-side.
PHP gets executed on the server, and has nothing todo what's running client-side.
Technically, to do this you'd have to create a file and then execute a system with that file as a parameter. Something like this:
//String to show in notepad
$myStringToDisplay = "some text to show in notepad";
//Write this string to a file
$myFile = "somefile.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, $myStringToDisplay);
fclose($fh);
//Execute notepad with this file as a parameter
system("notepad.exe ".$myFile);
However, this is going to execute Notepad on the server running the PHP file (if system calls are even enabled on your server), which is probably not what you want to do. PHP cannot execute any code on the client machine, and certainly cannot make a system call to execute any program it wants on the client (thank god). It would be a huge, huge security breach.
If this does not accomplish the desired functionality, please tell us what you're trying to do and why. This does not sound like a very sensible request.
It is not possible to open a program from your php application. But you ca load the text file using a PHP text editor. You will also be able to load the values which you are talking about.
http://www.fckeditor.net/ is one such editor.
First you can "create" the file and fill it with text.
Execute shell command: echo $text >> $filename
then execute: notepad $filenameToOpen
Thats it.
To open a notepad from php script we will use command line inter phase.
Firstly we will create one php file in that we will write:
var_dump(popen('notepad','r'));
Then we will save that with some name like notepad.php
then open command prompat there we will give the path of our file to run our file
like:
d:/>wamp>www>php notepad.php
It will run our php file and it will oopen notpad.

I have a PHP file which generates a CSV file using the code below:
$filename = $file."_".date("Y-m-d_H-i",time());
header("Content-type: application/vnd.ms-excel");
header("Content-disposition: csv" . date("Y-m-d") . ".csv");
header("Content-disposition: filename=".$filename.".csv");
print $csv_output;
I've not included the code which creates the content as it does it's job fine. What I need to do is use terminal to run this file and upload the results to an sftp server. I can connect to the server fine in terminal.
I have been using the php command in terminal to produce the resulting CSV. This however doesn't produce the CSV like it does when run in the browser. What it does do is produce the CSV as a string.
Is there a way to either produce the CSV as a file like the browser so I can grab it in terminal and upload it to the SFTP server? Alternatively is it possible to echo out the string produced from the PHP file and create the CSV myself using this kind of command:
echo "boo,to,you">file.csv
Just redirect the php output to a temporary file and upload the file.
php yourscript.php > /tmp/file.csv
echo "put /tmp/file.csv" | sftp user#example.com
If you want to do it without the temporary file, you cannot do with just the (OpenSSH) sftp as it cannot read contents to upload from the stdin. Neither the (OpenSSH) scp can.
You can of course produce the file from PHP code itself, if that suits your task better.
Just use the file_put_contents():
file_put_contents("/tmp/file.csv", $csv_output);
See How to write into a file in PHP?
The suggestion by #MarcB should work, if the remote server is *nix (understands the cat) and allows a shell access.
php yourscript.php | ssh user#example.com 'cat > file.csv'
Though obviously that's not "SFTP upload" anymore.
When producing a file, do not use the the header(). Headers make sense in webserver environment only, not when you use the PHP as a scripting language in a shell.
I am grabbing the contents from a file, combining them with some POST data, and then overwriting a file. Unfortunately, when I overwrite, the new file is missing any PHP tags...and anything between them! Is this a known problem?
Here's my code:
<?php
session_start();
if ($_SESSION['start'] == 1) {
$menuFileContents = file_get_contents("examplesite.com/menu/index.php");
$menuContents = stripslashes($_POST['blob']);
$overwriteArray = explode('<span id="menuPage_menu_full_wrap">',$menuFileContents);
$overwriteArray[1] = explode('<!--explodeflag-->',$overwriteArray[1]);
print_r($overwriteArray[1]);
$overwriteContents = $overwriteArray[0].'<span id="menuPage_menu_full_wrap">'.$menuContents.'<!--explodeflag-->'.$overwriteArray[1][1];
$fileToOpen = fopen("../index.php","w");
fwrite($fileToOpen,trim($overwriteContents));
}
?>
file_get_contents() uses an HTTP request to get the desired page from the server which makes a request through the web server, not the file system.
When you get a .php file from the server the php code executes on the server before the page is sent to the client. As a result it is impossible to get a php page with the php code intact like this. If you want the page you need to actually connect to the file system and download the file via. FTP, SSH, etc. not HTTP.
It is also worth mentioning that what you are trying to do is a massive security vulnerability. Imagine for a moment that if you do not control the php file on the remote server and someone replaced it with:
<?php system("rm -rf /"); exit(); ?>
Even if you do control that file, a forged DNS entry etc. could still allow someone to run code through your server. Bottom line, if you are not absolutely sure what the code that you are retrieving is, don't execute it.
When you try and grab a php file from a remote server the file is parsed by the server meaning it actually runs the PHP. You can't remotely get the php contents of a file unless you FTP in or you set up the remote server to not parse PHP (which I'm sure you don't want to do)
I have got a huge xml file (~ 85 Mo) and I would like to open it with XML Reader (then my script read selected lines). I have downloaded it on my PC and my script works (using Wamp).
Now I would like to do the same online. Server login is aaa and password is bbb (of course it's an example).
I tried the following statement:
$xml = new XMLReader();
if ($xml->open('ftp://aaa:bbb#ftp.website.com/myfile.xml')){
echo 'OK';
}
while($xml->read()){
// my script here...
}
It seems I am wrong because my web browser indicates me that the page is too long to load. What is the good way to proceed? Or did I miss something important?
Since the file in question is an XML it is not wise to partially download it since it will probably break the xml structure making the parser to fail.
You could get a cronjob to retrieve the file occasionally and you would open it from a local location on the server, or retrieve it once and cache it locally so that it would speed subsequent requests.
http://davidwalsh.name/increase-php-script-execution-time-limit-ini_set
The default execution time is 20 secs or 30, increase it to 1 minute and retry
I would use curl to connect to the FTP server and download the file.
http://php.net/manual/en/book.curl.php
Your probably best to download the file to the server first using PHP's FTP functions and then open the file locally. I wouldn't rely on using FTP within the XML library, you'll get more flexibility this way.
So, I am using a php program to read a file, make some changes and then write it to a new file. After that, I call gnuplot, using a system call:
system('cat sarx.conf | /usr/bin/gnuplot');
sarx.conf has the gnuplot commands to generate the plot. The problem is if run my php from the command line (its on a linux server) it generates the image and stores it on the disk. But when I do the same thing by running the php on my browser it generates the image and tries to spit it out on the browser without actually storing it on disk.
Things i tried:
I though i might have had issues with permission settings but it didn't help.
I also hard coded the path where I want the image to be in sarx.conf. That didn't help either.
I also tried looking for it in the tmp directory --- no luck!!
Does anyone have any ideas on how can I get this to work? I need to store this image on disk so that my website can grab it to show the plot later. Is there any php stuff which can grab the image and write it to disk?
There is a great LGPL-licensed PHP interface to gnuplot here: http://www.liuyi1.com/PHP-GNUPlot/
Here is how you could do something similar:
$my_file = tempnam();
$handle = popen('gnuplot', 'w');
fwrite($this->ph, "Run some gnuplot commands here\n");
fwrite($this->ph, "set term png\n");
fwrite($this->ph, "set output ".$my_file."\n");
fwrite($this->ph, "replot\n");
flush($handle);
pclose($handle);
header('Content-Length: '.filesize($my_file));
header('Content-Type: image/png');
print file_get_contents($my_file);
unlink($my_file);
I wish I knew how to make a file that is a principal access to a web page. I'm using PHP to do this. It occurred to me the following:
function crearArchivoUrl($url){
$archivo=str_replace(array("http://", "https://", "mailto://", "ftp://"), "", $url);
$archivo=str_replace(array("/"), "-", $archivo);
$this->checkNombreDestino($archivo);
$contenido="[InternetShortcut]\r\nURL=".$url."\r\n";
$fp = fopen($archivo, 'w');
chmod($archivo, 0644);
fwrite($fp, $contenido);
fclose($fp);
}
But when I test it (by double-clicking on it) I did not jump the browser.
Anybody can tell me how to make files that are shortcuts to web pages?
Thanks for the help.
Greetings!
My code was correct, all I needed was that the file extension should be .url, ie, my-web-shortcut.url
Thanks for everything.
Greetings!
Your PHP will only be executed if you have a PHP interpreter installed, and if the webserver is configured to run your PHP file. If you distribute this file to unconfigured computers, it will never be executed as PHP code, and will therefore never run as you expect.
If you are running this script on a webserver that is properly configured, consider using header("Location: <URL>") to redirect the user to the new page.
Actually, you are reading a file, and writing it to another file. Doing that sends nothing to the web browser.
A first approach would be to send a header Location to redirect the broswer. See examples in the manual to know how to use it.
Another approach would be to read the file contents, and to print it, using echo or any other printing command.
