Colorized output of bash script in php

tRolex · September 12, 2019

I'm trying to make colourized output of bash script in php. So far I have this:

<?php
$cmd = '/home/thebalk/FiveM/manage.sh restart';
while (@ ob_end_flush()); // end all output buffers if any

$proc = popen($cmd, 'r');
echo '<pre>';
while (!feof($proc))
{
    echo fread($proc, 4096);
    @ flush();
}
echo '</pre>';

//
// Converts Bashoutput to colored HTML
//
function convertBash($cmd) {
    $dictionary = array(
        '[1;30m' => '<span style="color:black">',
        '[1;31m' => '<span style="color:red">', 
        '[1;32m' => '<span style="color:green">',   
        '[1;33m' => '<span style="color:yellow">',
        '[1;34m' => '<span style="color:blue">',
        '[1;35m' => '<span style="color:purple">',
        '[1;36m' => '<span style="color:cyan">',
        '[1;37m' => '<span style="color:white">',
        '[m'   => '</span>'
    );
    $htmlString = str_replace(array_keys($dictionary), $dictionary, $cmd);
    return $htmlString;
}
?>

and my output looks like this:

[1;36m BOT:[0;39m THE [1;32m TheBalkanRP-SRV01-test SERVER [0;39m WAS RUNNING [1;36m BOT:[0;39m STOPPING THE [1;32m TheBalkanRP-SRV01-test SERVER [1;36m BOT:[0;39m GTA V SERVER HAS STOPPED [1;36m BOT:[0;39m REMOVING CACHE FOLDER [1;36m BOT:[1;31m CACHE FOLDER HAS BEEN REMOVED [0;39m [1;36m BOT:[0;39m STARTING THE [1;32m TheBalkanRP-SRV01-test [0;39m SERVER [1;36m BOT:[1;32m SERVER HAS STARTED [0;39m

I know my function is not connected with the code above but what is the right way to do it? Thank you!

You're missing that the escape sequence starts with a \033 (aka \e). And that's not a literal backslash, so if you add it into your $dictionary then you'll need to switch to double-quoted strings too.

Black is

\e[1;30m

where \e is a control character, like \n, and not literally a backslash + 'e'.

ok now i get it so i have to change this in bash script: WIT="\033[0;39m" ROOD="\033[1;31m" GROEN="\033[1;32m" but what about the part of code to use this function with the code above? Thank you for your help!

First, you need-- actually no, it can wait until you discover it for yourself.

convertBash() takes a string line of output as an argument and returns a new string with HTML markup. fread() reads from the process and returns a string line of output.

So instead of echoing the line of output, you run that line through convertBash and echo what it returns.

I understand but cant make it right..

I would like to make a script where admins can "start, restart" a game server "FiveM" this is the link of the script above: http://www.thebalkanrp.tk/start.php <--

My bash "start,restart" script looks like this:

#!/bin/bash

WIT="\033[0;39m"
ROOD="\033[1;31m"
GROEN="\033[1;32m"
GEEL="\033[1;33m"
PAARS="\033[1;35m"

LOL="\033[1;36m"


MSG_180="Une temp.te approche, dans 3 minutes la ville sera rasé !"

        echo -e "$GROEN Server screen [$SCREEN]. $WIT"
        screen -R $SCREEN
    ;;
    *)
    echo -e "$GEEL Use: $WIT ./manage.sh {start|stop|status|screen|restart}"
    exit 1
    ;;
esac

exit 0

And I would like colourized output of the script when I run http://www.thebalkanrp.tk/start.php

start.php should look something like:)

<?php
$cmd = '/home/thebalk/FiveM/manage.sh restart';
while (@ ob_end_flush()); // end all output buffers if any

$proc = popen($cmd, 'r');
echo '<pre>';
while (!feof($proc))
{
    echo fread($proc, 4096);
    @ flush();
}
echo '</pre>';

//
// Converts Bashoutput to colored HTML
//
function convertBash($cmd) {
    $dictionary = array(
        '\e[1;30m' => '<span style="color:black">',
        '\e[1;31m' => '<span style="color:red">', 
        '\e[1;32m' => '<span style="color:green">',   
        '\e[1;33m' => '<span style="color:yellow">',
        '\e[1;34m' => '<span style="color:blue">',
        '\e[1;35m' => '<span style="color:purple">',
        '\e[1;36m' => '<span style="color:cyan">',
        '\e[1;37m' => '<span style="color:white">'
    );
    $htmlString = str_replace(array_keys($dictionary), $dictionary, $cmd);
    return $htmlString;
}
?>

Okay. What (PHP code) do you have now and what problem are you having with it?

If you refresh or check my last quote you can see my (php code) which has to be rewritten in the right way.

requinix · September 12, 2019

And the problem is... that it's not replacing anything?

Metacharacters like \e do not work in single-quoted strings.

tRolex · September 12, 2019

So it would be easier to convert this bash script to php

requinix · September 12, 2019

No.

hehe I managed to fix it by changing bash script colors <span style="color:blue"> this instead of $GREEN and now the output is as it should be

tRolex · September 12, 2019

Here it is colourized php output:)
