在PHP的popen中格式化输出bash脚本

In my PHP script I'm executing a bash script with popen() and I output the response. But the response has a different encoding, and I don't know how to convert it.

I tried to convert it to utf8 but no results. Also tried to set the locale to nl_NL.utf8.

PHP function:

while (@ ob_end_flush()); // end all output buffers if any

$proc = popen("$cmd 2>&1 ; echo Exit status : $?", 'r');

$live_output     = "";
$complete_output = "";

while (!feof($proc))
{
    $live_output     = fread($proc, 4096);
    $complete_output = $complete_output . $live_output;
    echo "$live_output";
    @ flush();
}

pclose($proc);

Example response:

[2K[1A[2K[G
[2K[1A[2K[G⠋ load plugins
[2K[1A[2K[Gsuccess load plugins - 0.975 s
⠋ load plugins

This should be just:

success load plugins - 0.975 s

The ⠋ thing is a loader which is moving. Could that be the problem? Or are these characters the colorcode of the line?

Those are ANSI Escape Sequences, they are not bash commands but console commands used for coloring output or replacing/updating output on a single line.

Often commands offer a —no-color flag.

Also, a environment variable exists for common commands: NO_COLOR. Here's a list of common flags/variables to disable colored output => https://no-color.org/

Otherwise, you could always filter the output with a regex: /(\x9B|\x1B\[)[0-?]*[ -\/]*[@-~]/
