Run wget in php

Example Code for Calling Windows Application URL through Php’s Wget

Running an application from a service will not display its GUI as the service operates in a separate session that cannot interact with the user’s desktop. To better understand this, refer to the manual page for exec on http://php.net/manual/en/function.exec.php. Avoid attempting Solution 3 on most servers as they are usually blocked from running commands like wget. Instead, replace a crappy iframe with file_get_contents and quickly modify the font, images, and remove unwanted elements to improve the appearance of the site.

Call URL with wget and return an ERRORLEVEL depending on URL’s contents

Php — Call URL with wget and return an ERRORLEVEL, I was thinking about the Windows version of wget.

How to run wget from php so that output gets displayed in the browser window?

Instead of using a more complicated method, opt for file_get_contents which is much simpler.

echo file_get_contents('http://www.google.com'); 

If the usage of wget is necessary, one can attempt utilizing the following command:

$url = 'http://www.google.com'; $outputfile = "dl.html"; $cmd = "wget -q \"$url\" -O $outputfile"; exec($cmd); echo file_get_contents($outputfile); 

The usage of the exec function enables the execution of wget. Although my experience with wget is limited to basic file downloads, the command-line arguments specified for wget can be employed to generate the desired output. As for the exec method’s second argument, it is an array that receives the output of wget line by line.

So you would have something like:

For a better explanation, refer to the manual page for exec available at http://php.net/manual/en/function.exec.php.

Running commands like wget is typically blocked on most servers, so trying to do so is not recommended. Instead, my client requested that I use file_get_contents to replace the iframe they originally had, which was a quick and effective solution.

]+\>/i", " ", $content); $content = preg_replace("/]+\>/i", " ", $content); $echo $content; ?> 

After making some changes to the font and removing unnecessary images and iframes, my website now looks much better. Although I admit my coding skills are not exceptional, the improvement is significant and it has also eliminated some frustrating formatting issues.

PHP how to launch windows GUI application

My assumption is that PHP is being executed by a service called Apache.

Initiating an application from a service will no longer show its graphical user interface since the service operates in a distinct session that prohibits communication with the user’s desktop.

For further information, refer to the response provided regarding the issue of C# service not displaying GUI while initiating a process.

There may be alternative methods to accomplish this goal.

1. Develop a personalized application using C++ (or a similar language) to generate the desired GUI application for the designated user. The approach outlined in the response to «How can a Windows service execute create a GUI application?» ( CreateProcessAsUser() ) can be utilized for this purpose, which necessitates the provision of the user’s username and password.
2. Develop an application that includes a custom client and server. The server component should consistently operate in User mode and display the GUI. The client will be triggered by PHP and use IPC event signaling to communicate with the server. Once notified, the server can initiate the GUI application.
3. In four consecutive sentences, the following points are discussed: — MSDT P1 — MSDT P2 — MSDT P3 — MSDT P4

The image is downloaded successfully using wget http://mydomain.com/image.jpg from the command line.

Whenever I insert this piece of code in any of the following locations: exec() , system() , or passthru() , for instance,

exec('wget http://mydomain.com/image.jpg'); 

Alternately, it can be done using either system() or passthru() .

The resulting image is generated, but its size is limited to 255 bytes.

Is there anyone who can explain the reason behind this occurrence?

To resolve the issue, you could consider utilizing the quiet option (-q) and specifying an output file (-O) instead. The problem could be caused by the frequent status updates.

Downloading PHP files from open directory using wget gives empty/blank PHP files

After using wget to download a directory folder, I noticed that all the PHP files were empty. Despite showing a file size on the web directory, I expected the files to contain content.

The location of the folder I intend to download is as follows:

The URL mentioned belongs to the AutomateWoo Referrals plugin hosted on the iSuperman website.

These instructions were followed to reach Download recursively with wget.

How can I obtain an HTTP directory that includes all files and subdirectories in the same order as they appear in the online file/folder list?

Can you suggest any reasons for the empty downloads?

Access the source code of automatewoo-referrals.php file on isuperman.tw website by typing «view-source:https://www.isuperman.tw/wp-content/plugins/automatewoo-referrals/automatewoo-referrals.php» in the browser’s address bar.

Run script after wget downloading is complete (wget background mode)

After completing the download, I want to execute a PHP script, which can be achieved without difficulty using a method like.

wget http://example.com && php script.php 

However, I make use of wget’s background downloading feature, as demonstrated in wget -b , resulting in an output similar to Continuing in background, pid 12345 .

Is it feasible to execute wget in the background and then run a script once the download is complete?

By using the -b option with wget, a subprocess is created in a separate shell session (setsid), and the original process terminates once the subprocess is launched.

As the subprocess runs is active in a separate shell session, utilizing wait command is not possible. However, we can create a loop that verifies if the subprocess is still running, and we require the subprocess’s PID for this purpose.

wget -b http://example.com && \ ( PID=`pidof wget | rev | cut -f1 | rev`; while kill -0 $PID 2> /dev/null; do sleep 1; done; ) && \ php script.php & 

Parsing the output of wget could provide an alternative means of obtaining the subprocess’s PID.

To comprehend the functioning of the background option in wget, one can refer to the C source code.

. pid = fork (); if (pid < 0) < perror ("fork"); exit (1); >else if (pid != 0) < printf (_("Continuing in background, pid %d.\n"), (int)pid); if (logfile_changed) printf (_("Output will be written to `%s'.\n"), opt.lfilename); exit (0); >setsid (); freopen ("/dev/null", "r", stdin); freopen ("/dev/null", "w", stdout); freopen ("/dev/null", "w", stderr); . 

Prevent WGET and other automated downloading of website

My PHP website has been experiencing a surge of automated hits from a particular source over the past few weeks. It appears that instead of using a proper browser to access the site, someone is using automated tools such as WGET or CURL to «poach» the content.

Is it possible to prevent automated access?

To explore the issue, I experimented with WGET on renowned websites such as Yahoo, US News, and Bloomberg. While Yahoo and US News pages (HTML code) were successfully downloaded, my trial on a Bloomberg sample page proved unsuccessful.

It seems that Bloomberg has found a solution to prevent automated access, while the question remains if there are any measures a webmaster can take to achieve the same.

Although I concur with the idea of free internet access, there may be instances where it becomes necessary to establish certain limitations to prevent unauthorized entry.
