PHP. fputs(STDOUT, 'some short text')! Is there any way to get char length for terminal that launch php script?
How to print text with fputs(STDOUT, "Some Error "); with full line background of red color?
This will output a line with "=" characters filling the whole line of the terminal. Will work on linux-based system.
// 'tput cols' is a shell command which returns
// the number of chars to fill up the whole
// line of the current terminal.
$colCount = shell_exec('tput cols');
// Create the string filling the whole line
$string = str_repeat("=", intval($colCount));
// This is the way to print out text with coloured background
// 48, 5, 160 representing 256-colour of red, green and blue.
fputs(STDOUT, "\e[48;5;160m".$string."\e[0m");
Which can be condensed to one line
fputs(STDOUT, "\e[48;5;160m".str_repeat("=", intval(shell_exec('tput cols')))."\e[0m");
Here's a script to ANSI color code in XTerm/ANSI-compatible terminals with a 256-color palette support if you want to know more about displaying colours on terminal.
You can use Symfony\Console for this, since it has Terminal class that does exactly what you need:
composer require symfony/console
index.php<?php
require __DIR__ . '/vendor/autoload.php';
$terminal = new Symfony\Component\Console\Terminal;
$terminalWidth = $terminal->getWidth();
var_dump($terminalWidth);
$ php index.php
int(80)
