PHP 日志文件颜色

Question

我正在编写一个 PHP 日志文件类，但我想为写入文件的行添加颜色。

我遇到的问题是颜色也会改变终端的颜色，我想要实现的是只改变写入日志文件的行的颜色。

class logClass extends Singleton {

    private function checkDate() {
        return date("onSj");
    }

    public function logNotice($str) {
        $this->write($str, "\033[33m");
    }

    public function write($string, $color) {
        $fileName = $this->checkDate();
        $handle = fopen('error.log', 'a');
        fwrite($handle, "$color" . date("Y-m-d H:i:s") . $string . "\n");
       fclose($handle);
    }
}

您应该添加一个结束颜色标记序列。例如:sprintf("\033[33m%s\033[0m", $text)

这是从 https://github.com/kevinlebrun/colors.php 中提取的颜色代码列表

$colorFormats = array(
        // styles
        // italic and blink may not work depending of your terminal
        'bold' => "\033[1m%s\033[0m",
        'dark' => "\033[2m%s\033[0m",
        'italic' => "\033[3m%s\033[0m",
        'underline' => "\033[4m%s\033[0m",
        'blink' => "\033[5m%s\033[0m",
        'reverse' => "\033[7m%s\033[0m",
        'concealed' => "\033[8m%s\033[0m",
        // foreground colors
        'black' => "\033[30m%s\033[0m",
        'red' => "\033[31m%s\033[0m",
        'green' => "\033[32m%s\033[0m",
        'yellow' => "\033[33m%s\033[0m",
        'blue' => "\033[34m%s\033[0m",
        'magenta' => "\033[35m%s\033[0m",
        'cyan' => "\033[36m%s\033[0m",
        'white' => "\033[37m%s\033[0m",
        // background colors
        'bg_black' => "\033[40m%s\033[0m",
        'bg_red' => "\033[41m%s\033[0m",
        'bg_green' => "\033[42m%s\033[0m",
        'bg_yellow' => "\033[43m%s\033[0m",
        'bg_blue' => "\033[44m%s\033[0m",
        'bg_magenta' => "\033[45m%s\033[0m",
        'bg_cyan' => "\033[46m%s\033[0m",
        'bg_white' => "\033[47m%s\033[0m",
    );

示例用法:

sprintf($colorFormats['green'], $someText)
