如何启用 CLI 输出的颜色？ 下面是在 Ubuntu 上运行的。
如果您看到屏幕截图，显然终端的颜色已启用。而且，如果我调用echo，它不会对结果着色，但如果我使用echo -e，它会着色。
我检查了echo 的手册页，-e 表示启用反斜杠转义解释
如何为 PHP CLI 启用此选项？

\e 替换为 033 后它起作用了。谢谢。
echo的序列，而是使用ANSI-C引用直接在字符串中生成ANSI序列：$'\e[31mblah blah\e[0m。这样您就不需要记住\033 或其他任何内容。
懒人
function colorLog($str, $type = 'i'){
switch ($type) {
case 'e': //error
echo "\033[31m$str \033[0m\n";
break;
case 's': //success
echo "\033[32m$str \033[0m\n";
break;
case 'w': //warning
echo "\033[33m$str \033[0m\n";
break;
case 'i': //info
echo "\033[36m$str \033[0m\n";
break;
default:
# code...
break;
}
}

做了一些实验后，我做了这些代码：
function formatPrint(array $format=[],string $text = '') {
$codes=[
'bold'=>1,
'italic'=>3, 'underline'=>4, 'strikethrough'=>9,
'black'=>30, 'red'=>31, 'green'=>32, 'yellow'=>33,'blue'=>34, 'magenta'=>35, 'cyan'=>36, 'white'=>37,
'blackbg'=>40, 'redbg'=>41, 'greenbg'=>42, 'yellowbg'=>44,'bluebg'=>44, 'magentabg'=>45, 'cyanbg'=>46, 'lightgreybg'=>47
];
$formatMap = array_map(function ($v) use ($codes) { return $codes[$v]; }, $format);
echo "\e[".implode(';',$formatMap).'m'.$text."\e[0m";
}
function formatPrintLn(array $format=[], string $text='') {
formatPrint($format, $text); echo "\r\n";
}
//Examples:
formatPrint(['blue', 'bold', 'italic','strikethrough'], "Wohoo");
formatPrintLn(['yellow', 'italic'], " I'm invicible");
formatPrintLn(['yellow', 'bold'], "I'm invicible");
只需复制并粘贴上面的代码，然后...享受吧:)

可重用类形式的更清洁解决方案。
PHP 类：
class CLI
{
// this method requires one variable. the second, color, is optional
function cout_color($content, $color=null)
{
// if a color is set use the color set.
if(!empty($color))
{
// if our color string is not a numeric value
if(!is_numeric($color))
{
//lowercase our string value.
$c = strtolower($color);
}
else
{
// check if our color value is not empty.
if(!empty($color))
{
$c = $color;
}
else
{
// no color was set so lets pick a random one...
$c = rand(1,14);
}
}
}
else // no color argument was passed, so lets pick a random one w00t
{
$c = rand(1,14);
}
$cheader = '';
$cfooter = "\033[0m";
// let check which color code was used so we can then wrap our content.
switch($c)
{
case 1:
case 'red':
// color code header.
$cheader .= "\033[31m";
break;
case 2:
case 'green':
// color code header.
$cheader .= "\033[32m";
break;
case 3:
case 'yellow':
// color code header.
$cheader .= "\033[33m";
break;
case 4:
case 'blue':
// color code header.
$cheader .= "\033[34m";
break;
case 5:
case 'magenta':
// color code header.
$cheader .= "\033[35m";
break;
case 6:
case 'cyan':
// color code header.
$cheader .= "\033[36m";
break;
case 7:
case 'light grey':
// color code header.
$cheader .= "\033[37m";
break;
case 8:
case 'dark grey':
// color code header.
$cheader .= "\033[90m";
break;
case 9:
case 'light red':
// color code header.
$cheader .= "\033[91m";
break;
case 10:
case 'light green':
// color code header.
$cheader .= "\033[92m";
break;
case 11:
case 'light yellow':
// color code header.
$cheader .= "\033[93m";
break;
case 12:
case 'light blue':
// color code header.
$cheader .= "\033[94m";
break;
case 13:
case 'light magenta':
// color code header.
$cheader .= "\033[95m";
break;
case 14:
case 'light cyan':
// color code header.
$cheader .= "\033[92m";
break;
}
// wrap our content.
$content = $cheader.$content.$cfooter;
//return our new content.
return $content;
}
}
基本用法：
//create a new object
$cli = new CLI();
//example string
$text = 'Success!';
//color via class color id
$text = $cli->cout_color($text, 2);
//color via string name
//$text = $cli->cout_color($text, 'green');
//for random color, ignore the second parameter.:
//$text = $cli->cout_color($text);
echo $text;
根据您的项目要求进行修改。祝你好运。
