Php get process list

Retrieving process details using a process ID in Linux with PHP

To obtain a list of files open by a particular process, you can utilize various solutions. The first solution is to use the command and filter the output using options such as excluding PHP runtime, including path with your files, and keeping only regular files. Another solution involves checking for processes with arguments using a specific method. The third solution is to use the system PHP call and pass a shell command to get process information, which can then be piped through grep with the PID to find the process name.

Find exact script from PID

To display the complete command line used to initiate a process.

In case the aforementioned solution is insufficient, you have the option of obtaining the inventory of files being accessed by said process through:

The extensive result can be managed with the help of grep . This tool enables you to keep regular files, exclude PHP runtime, and include the path of your files, among other things. Additionally, examining the open files may provide a clue.

PHP Process ID and unique, I want to run a php script on background and store its PID on database. So that I can check if the particular script running or not (later). We can use getmypid

How can I find pid of my PHP job on Linux?

To avoid modifying the output of ps , refrain from using grep and opt for pgrep instead. In case you have a single PHP process operating, you can locate it by name using the following method:

Upon execution, an output in the form of 49282 shall be generated.

Given that multiple processes are running, distinguishing between them is possible by utilizing the following code: pgrep —full . Suppose two commands are being executed, namely php foo.php and php bar.php , and it is necessary to obtain the process ID for the process that is running foo.php .

Not always required, but helpful in avoiding false-positive matches, the use of ^ and $ is recommended. You can refer to the documentation that is specific to grep for more information on regular expressions.

Unless I am mistaken, the code that follows should be functional for you.

To avoid incorrect results, it’s advisable to recall the PIDs once the sub processes are established instead of scrutinizing the entire process list.

An alternative approach would be to identify and recall the initiator of the sub-processes, and subsequently locate their associated offspring processes.

Unfortunately, the information you provided was insufficient for us to offer more targeted assistance.

PHP echo memory by process ID, 1) Do you know what tail does? · 1. So you copy and paste code, it didn’t work, so you posted to stackoverflow.com. · I have been playing with

Get program name for PID using PHP

Obtain the command line through /proc/PID/cmdline and eliminate the null byte located at the end.

$cmd = trim(file_get_contents("/proc/$pid/cmdline"), "\0"); 

Use the following method to verify processes along with their arguments.

$cmd = str_replace("\0", " ", trim(file_get_contents("/proc/$pid/cmdline"), "\0")); 

One way to retrieve the name of a process is by utilizing the system php call. This can be done by passing a shell command to look up process information, which can then be piped through grep along with the PID.

PHP Check Process ID, In linux, you would look at /proc. return file_exists( «/proc/$pid» );. In Windows you could shell_exec() tasklist.exe, and that would find

PHP get PID of process and kill it

Give the command pgrep a try.

$command = "pgrep programname"; $pid = shell_exec($command); 

My proposed resolution would be as follows:

$command = 'ctorrent -x "/var/www/html/torrents/'.$torrentName.'"'; $outputfile = "output.out"; $pidfile = "pidfile.pid"; exec(sprintf("%s > %s 2>&1 & echo $! >> %s", $command, $outputfile, $pidfile)); $pid = file_get_contents($pidfile); $outout = file_get_contents($outputfile); 

As per your writing, it is possible to terminate the process.

After receiving advice from various individuals, I finally found a solution. In the end, I added . ‘ & echo $!; ‘; at the end of the code as suggested by ineersa. However, this caused the PID to be added at the beginning of my output text. But with a simple fix, I was able to capture only the first line of the output, and now it functions perfectly.

$command = "ctorrent -x \"/var/www/html/torrents/$torrentName\""; $output = shell_exec($command); echo "
"; echo $output; echo "

The ProcessList class provides a platform-independent way to retrieve the list of processes running on your systems. It works both on the Windows and Unix platforms.
 
To retrieve the list of processes currently running on your system, simply use the following :
 
require ( 'ProcessList.phpclass' ) ; $ps = new ProcessList ( ) ; 
 
The $ps variable can now be accessed as an array to retrieve process information, which is simply an object of class Process :
 
foreach ( $ps as $process ) echo ( "PID : ProcessId>, COMMAND : Command>" ) ; 
 
Whether you are running on Windows or Unix, the properties exposed by the Process objects remain the same (see the Reference section).
 
For Windows platforms, you will need the following package :
 
http://www.phpclasses.org/package/10001-PHP-Provides-access-to-Windows-WMI.html 
 
A copy of the source code is provided here for your convenience, but it may not be the latest release.
 
The ProcessList class is a container class that allows you to retrieve information about individual processes. It implements the ArrayAccess and Iterator interfaces, so that you can loop through each process currently running on your system.
 
Each element of a ProcessList array is an object of class Process.
 
public function __construct ( $load = true ) ; 
 
Creates a process list object. If the $load parameter is true, the process list will be retrieved ; otherwise, you will need to call the Refresh() method later before looping through the list of available processes.
 
public function GetProcess ( $id ) ; 
 
Searches for a process having the specified $id.
 
Returns an object of class Process if found, or false otherwise.
 
public function GetProcessByName ( $name ) ; 
 
Searches for a process having the specified name. The name is given by the Command property of the Process object.
 
public function GetChildren ( $id ) ; 
 
Returns the children of the specified process, or an empty array if $id does not specify a valid process id.
 
Refreshes the current process list. This function can be called as many times as desired on the same ProcessList object.
 
The Process class does not contain methods, but simply expose properties that contain information about a process.
 
Contains the command-line arguments of the process. As for C (and PHP) programs, Argv[0] represents the command path.
 
Command name, without its leading path.
 
Full command line, including arguments.
 
CPU time consumed by the process, in the form "hh:mm:ss".
 
Dd of the parent process for this process.
 
Process id of the current process.
 
Process start time, in the form "yyyy-mm-dd hh:mm:ss".
 
Process title. On Windows systems, it will be the title of the process. Since there is no notion of process title on Unix systems, it will be set to the value of the Command property.
 
Attached tty. This information is useful mainly for Unix systems.
 
User name running the process. On Unix systems, this can be either a user name or a user id.

Complete Code to Check Process Running in Windows Using PHP
 
Code Explanation:
 
 
In the above code, we use the PHP tasklist command to see what processes are running in Windows.
 
exec is the PHP inbuilt function used to execute an external program and return the last value, if there is no return then it returns the NULL value.
 
In the last line, we print the $task_list variable where we store the list of running processes in windows.
 
 
Output:
 
 
You can check it by running it on your local machine using XAMP or WAMP.
 
How to Kill Windows Process Using PHP
 
Code Explanation:
 
In the above code, we use the same exec() function to execute the PHP tasklist command and by using taskName from the list we can kill the process.
 
Here is the complete explanation of how we can check processes running in windows PHP and also kill by using the command.
 
To know more you can check PHP: getmypid – Manual.
