Setting proc title on PHP based daemons is pretty sweet.
(PHP 5 >= 5.5.0, PHP 7, PHP 8)
cli_set_process_title — プロセスのタイトルを設定する
$title): boolプロセスのタイトルを設定します。これは top や ps といったツールで表示されます。 この関数は、 CLI モードでしか使えません。
title新しいタイトル。
成功した場合に true を、失敗した場合に false を返します。
OS がこの機能に対応していない場合に E_WARNING
が発生します。
例1 cli_set_process_title() の例
<?php
$title = "My Amazing PHP Script";
$pid = getmypid(); // これを使えば、プロセスのタイトルを ps で確認できます
if (!cli_set_process_title($title)) {
echo "Unable to set process title for PID $pid...\n";
exit(1);
} else {
echo "The process title '$title' for PID $pid has been set for your process!\n";
sleep(5);
}
?>
In Linux this command changes the title for commands like 'ps -a' it doesn't seem to work with 'top' or 'pkill'
To change the short name (eg PHP) to something else you can use the below:
<?php
$strNewName='myscript';
cli_set_process_name($strNewName);
cli_set_process_title($strNewName);
var_dump(cli_get_process_name());
var_dump(cli_get_process_title());
function cli_set_process_name($strName)
{
file_put_contents("/proc/".getmypid()."/comm",$strName);
}
function cli_get_process_name()
{
return(trim(file_get_contents("/proc/".getmypid()."/comm"),"\r\n"));
}
Note: The above will NOT work in Windows and may not work in all flavours of linux (I use Debian).
Please note that the function might be inconsistent depending on your system.
On 2 of my systems (CentOS 7.7 and Linux Mint 18.3), setting the title will work for ps but not for top.
<?php
cli_set_process_title("sleeping-daemon");
sleep(100);
/*
*ps* returns
25072 pts/2 S 0:00 sleeping-daemon
*top* returns
25072 aurelien 20 0 285848 23256 16856 S 0.0 0.3 0:00.01 php
*/
In Windows, this function will set the Command Prompt window title, which is restored to the previous setting once the script finishes. If you need to do this in 5.5.X and below, you'll need to use system() to run the title command.
cli_set_process_title() change name only for some process manager in linux. In fact this function change value appear in /proc/self/cmdline and not value in /proc/self/comm. This value in comm file is used as name in #ps or #pstree and other process manager.
For changing proccess name completly in linux you could add after cli_set_process_title() this code:
$f = fopen('/proc/self/comm','w');
if ($f) { fwrite($f, 'my-new-app-name'); fclose($f);
