Bash script colored output to browser with php

I have a php file which currently puts in the browser the output of a bash script:

<?php
ob_implicit_flush(true);
ob_end_flush();

$cmd = "./bash_script.sh";

$descriptorspec = array(
  0 => array("pipe", "r"),
  1 => array("pipe", "w"),
  2 => array("pipe", "w")
);

$process = proc_open($cmd, $descriptorspec, $pipes, realpath('./'), array());

echo '<pre>';
if (is_resource($process)) {
  while ($s = fgets($pipes[1])) {
    print $s;
  }
}
echo '</pre>';
?>

However, in CLI the output of my bash_script.sh is colored formatted but in the browser output there is no formatting and colors are not visible.

I have tried the following simple example with command ls --color:

<?php
$cmd = "ls --color";
$descriptorspec = array(
  0 => array("pipe", "r"),
  1 => array("pipe", "w"),
  2 => array("pipe", "w")
);
$process = proc_open($cmd, $descriptorspec, $pipes, realpath('./'), array());
echo '<pre>';
if (is_resource($process)) {
  while ($s = fgets($pipes[1])) {
  print $s;
  }
}
echo '</pre>';
?>

And its output comes with color codes (or at least I believe so), that is:

[01;34mFolder1[0m

[01;34mFolder2[0m

[01;34mFolder3[0m

[01;32mFile1[0m

[01;34mFolder4[0m

However, with my script, those color codes don't appear.

Is it possible to print the same colored output I get in CLI to the browser?

Since there are color formats in the output, you could set a translations table that converts between the cli and php.

A quick-n-dirty example:

  1. Define translations
    $colors = ['[01;32m' => '<span style="color:green">', …, '[0m' => '</span>']

  2. Then replace
    str_replace(array_keys($colors), array_values($colors))

NOTE: usually color formats are defined in this form \e[32mHello world, where \e is a shortand for ESCAPE char, so see case by case forms of defining a color format.

Tool way: you might also try if this works fine: aha, an Ansi HTML Adapter.
