PHP tput: No value for $TERM and no -T specified

Question

I'm having the following error when using the exec() function:

string(25) "/etc/init.d/mast list-log" 
array(1) { [0]=> string(44) "tput: No value for $TERM and no -T specified" } 
tput: No value for $TERM and no -T specified

My command is /etc/init.d/mast list-log and was working prior to reboot. I can't see what the difference.

Source code

public static function execute($_ = null, $debug=true) {
    $_ = $debug ? $_." 2>&1"  : $_;
    exec("$_ | aha --word-wrap --no-header", $output, $exitCode);
    return $output;
}

Question

Do you have suggestion on how to solve this?

Answer 1

In shell you can set an environment variable that has the life cycle of the following command as follow:

TERM=screen-256color ls -l --color=always

Where TERM=screen-256color is the environment variable and ls -l --color=always the command.

Solution

Here is my modified code, I simply prepend TERM=screen-256color to my command:

public static function execute($_ = null, $debug=true) {
    $_ = $debug ? $_." 2>&1"  : $_;
    exec("TERM=screen-256color $_ | aha --word-wrap --no-header", $output, $exitCode);
    return $output;
}
