学习PHP-cli 模式在终端输出彩色标记文字以及动态内容

                                                       

文字的各种效果标记写法

1. 字体颜色与背景色

    \033[30m 至 \33[37m 设置前景色  
    \033[40m 至 \33[47m 设置背景色  
    例如 echo "\033[30m  this is a test msg  \033[0m".PHP_EOL； 
         echo "\033[45m  this is a test msg  \033[0m".PHP_EOL；
    文字背景颜色范围:
    40:黑  
    41:深红  
    42:绿  
    43:黄色  
    44:蓝色  
    45:紫色  
    46:深绿  
    47:白色  
   
    文字颜色:
    30:黑  
    31:红  
    32:绿  
    33:黄  
    34:蓝色  
    35:紫色  
    36:深绿   
    37:白色

2. 标记闭合

     所有效果在文本结尾处要加上闭合的标记：\033[0m；

3. 文字高亮等其他效果

    \033[1m 文字高亮
    \033[4m 下划线
    \033[5m 闪烁
    \033[7m 反显
    \033[8m 消隐

4. 多种效果组合使用

     多种效果组合使用时用英文分号隔开，例如蓝底红字下划线加闪烁
     echo "\033[44;31;4m  this is a test msg  \033[0m".PHP_EOL；

光标的移动与设置

1. 移动

    \033[nA 光标上移n行   
    \033[nB 光标下移n行  
    \033[nC 光标右移n行  
    \033[nD 光标左移n行

2. 设置

    \033[y;xH设置光标位置  
    \033[2J 清屏  
    \033[K 清除从光标到行尾的内容  
    \033[s 保存光标位置   
    \033[u 恢复光标位置  
    \033[?25l 隐藏光标  
    \033[?25h 显示光标

简单的实现

1. 文字效果操作类

   namespace Console;class Style{
        private $colors = [
            "black"=>30,
            "red"=>31,
            "green"=>32,
            "yellow"=>33,
            "blue"=>34,
            "purple"=>35,
            "darkGreen"=>36,
            "white"=>37,
        ];
        private $backgrounds = [
            "black"=>40,
            "darkRed"=>41,
            "green"=>42,
            "yellow"=>43,
            "blue"=>44,
            "purple"=>45,
            "darkGreen"=>46,
            "white"=>47,
        ];
   
        public $msg;
        public $style = [];
        public function __construct($msg){
            $this->msg = $msg;
        }
        // 设置文本颜色
        public function color( string $c ){
            if( isset( $this->colors[$c]) ) $this->style[] = $this->colors[$c];
            return $this;
        }
        // 设置背景色
        public function bg( string $c ){
            if(isset($this->backgrounds[$c]) ) $this->style[] = $this->backgrounds[$c];
            return $this;
        }
        // 高亮
        public function highLight(){
            $this->style[] = 1;
            return $this;
        }
        // 下划线
        public function underLine(){
            $this->style[] = 4;
            return $this;
        }
        // 闪烁
        public function twinkle(){
            $this->style[] = 5;
            return $this;
        }
        // 反显
        public function rshow(){
            $this->style[] = 7;
            return $this;
        }
        //  消隐
        public function hide(){
            $this->style[] = 8;
            return $this;
        }
   
        public function toString(){
            $this->style = array_unique($this->style);
            if($this->msg){
                if(sizeof($this->style)  ){
                    return "\033[".implode(';',$this->style)."m"  . $this->msg . "\033[0m";
                }else{
                    return $this->msg. "\033[0m";
                }
            }else{
                return false;
            }
        }
    }

2. 光标操作类

   namespace Console;
   
    // 光标的信息以及操作
    class Cursor{
        // 光标设置 \033[y;xH
        private $x=0;
        private $y=0;
        // 获取光标X轴位置
        public function offsetX(){
            return $this->x;
        }
        // 获取光标Y轴位置
        public function offsetY(){
            return $this->y;
        }
   
        // 获取光标坐标
        public function offset(){
            return [
                'x'=>$this->x,
                'y'=>$this->y,
            ];
        }
        public function setX( int $x ){
            $this->x = $x;
        }
   
        public function setY( int $y ){
            $this->y = $y;
        }
   
        public function setOffset( int $x , int $y ){
            $this->x = $x;
            $this->y = $y;
            return $this->toString();
        }
        // 清屏
        public function clear(){
            return "\033[2J";
        }
   
        public function show(){
            return "\33[?25h";
        }
        public function hide(){
            return "\33[?25l";
        }
   
        public function toString(){
            if($this->x<0)$dx = &#39;D&#39;;
            else $dx = &#39;C&#39;;
            if($this->y<0)$dy = &#39;A&#39;;
            else $dy = &#39;B&#39;;
            $absx = abs($this->x);
            $absy = abs($this->y);
            return "\033[{$absx}{$dx}\033[{$absy}{$dy}";
        }
    }

3. table类，通便html的table标记语言，输出table

   namespace Console;class Table{
        public $table=[];
        private $getV;
        private $currentTag='table';
        private $props = [
            'color','bg','twinkle','highLight','underLine','colspan','rowspan','width','border','align'
        ];
        public function __construct( string $html){
            // 解析字符串最好
            $this->html=$html;
            $this->parse();
        }
        // 解析字符串 将table的每个tr td以及属性都解析出来 
        private function parse(){
            if( !preg_match("/<table(\s+.*?)?>(.*?)<\/table>/is",$this->html) || !preg_match("/<tr(\s+.*?)?>(.*?)<\/tr>/is",$this->html) || !preg_match("/<td(\s+.*?)?>(.*?)<\/td>/is",$this->html) ){
                die(&#39;标签有误，必须包含table tr  td标签且标签闭合&#39;);
            }
   
            $this->table[&#39;html&#39;] = $this->html;
            $this->getPrototype(&#39;table&#39;,$this->table);
            preg_match_all("/<table(\s+.*?)?>(.*?)<\/table>/is",$this->html,$innerTable);
            if( $innerTable[0][0] ){
                preg_match_all("/<tr(\s+.*?)?>(.*?)<\/tr>/is",$this->html,$trList);
                if( $trList[0] ){
                    $this->table[&#39;tr&#39;] = $trList[0];
                    foreach($this->table[&#39;tr&#39;] as $k=>$tr){
                        $this->table[&#39;tr&#39;][$k] = [];
                        preg_match_all("/<td(\s+.*?)?>(.*?)<\/td>/is",$tr,$tdList);
                        $this->table[&#39;tr&#39;][$k][&#39;td&#39;] = $tdList[0];
                        $this->table[&#39;tr&#39;][$k][&#39;html&#39;] =$tr;
                        $this->getPrototype(&#39;tr&#39;,$this->table[&#39;tr&#39;][$k]);
                        foreach ($this->table[&#39;tr&#39;][$k][&#39;td&#39;] as $kk=>$td){
                            $this->table[&#39;tr&#39;][$k][&#39;td&#39;][$kk] = [
                                &#39;html&#39;=>$td,
                                &#39;content&#39;=>$tdList[2][$kk]
                            ];
                            $this->getPrototype(&#39;td&#39;,$this->table[&#39;tr&#39;][$k][&#39;td&#39;][$kk]);
                        }
                    }
                }else{
                    die(&#39;Tr 不存在&#39;);
                }
            }else{
                die(&#39;Table 不存在&#39;);
            }
        }
        private function getPrototype(string $tag,&$v){
            preg_match("/<{$tag}(\s.*?)?>(.*?)<\/{$tag}>/is",$v[&#39;html&#39;],$arr);
            if(strlen($arr[1])){
                $arr2 = explode(" ", trim(preg_replace("/( +)/is"," ",$arr[1])));
                foreach ($arr2 as $arr3){
                    $arr4 = explode(&#39;=&#39;,str_replace([&#39; &#39;,"\"","\&#39;"],&#39;&#39;,$arr3));
                    if(in_array($arr4[0],$this->props)){
                        $v[$arr4[0]] = $arr4[1];
                    }
                }
            }
        }
    }

4. console类，输出自定义的文本或table格式文本

   namespace Console;class Console{
        public $cursor;
        private $msgList=[];
        private $lastCountLine=0;
        public function __construct(){
            $this->cursor= new Cursor();
        }
   
        private static function getStrlen($str){
            if(!$str) return 0;
            $l=0;
            $strArr = preg_split('//u',$str,-1, PREG_SPLIT_NO_EMPTY);
            if(is_array($strArr)){
                foreach($strArr as $v){
                    if(preg_match("/^[\x{4e00}-\x{9fa5}]$/u", $v)) $l += 2;
                    else $l += 1;
                }
            }
            return $l;
        }
   
        public function write($msg){
            $msgStyle = new Style($msg);
            $this->msgList[] =  $msgStyle;
            return  $msgStyle;
        }
   
        public function table(array $table){
            foreach($table['tr'] as $tr){
   
                foreach($tr['td'] as $td){
                    if($td['content']){
                        $len = self::getStrlen($td['content']); // 显示问题矫正
                        $tdlen = $td['width'] ?? max(15,$len);
                        $tdlen = max($tdlen,$len);
                        $align = $td['align'] ??$tr['align']??$table['align']?? false;
                        if( $tdlen>$len ){
                            if( $align=='left'){
                                $td['content'] =  $td['content'].str_repeat(' ',$tdlen-$len);
                            }else if($align=='right'){
                                $td['content'] = str_repeat(' ',$tdlen-$len) . $td['content'];
                            }else{
                                $td['content'] = str_repeat(' ',floor(($tdlen-$len)/2)) . $td['content'] . str_repeat(' ',ceil(($tdlen-$len)/2));
                            }
                        }
                        $msg = $this->write($td['content']);
                        $color = $td['color']  ??   $tr['color'] ??$table['color']??false;
                        $twinkle = $td['twinkle']  ??   $tr['twinkle'] ??$table['twinkle']??false;
                        $bg  = $td['bg ']  ??   $tr['bg '] ??$table['bg ']??false;
                        $highLight = $td['highLight']  ??   $tr['highLight'] ??$table['highLight']??false;
                        $underLine = $td['underLine']  ??   $tr['underLine'] ??$table['underLine']??false;
   
                        if($color) $msg->color($color);
                        if($bg) $msg->bg($bg);
                        if($twinkle) $msg->twinkle();
                        if($highLight) $msg->highLight();
                        if($underLine) $msg->underLine();
                    }
                }
                $this->write("\n");
   
            }
   
            $this->dump();
        }
        public function dump(){
            foreach( $this->msgList as $msg){
                echo $msg->toString();
            }
            $this->lastCountLine = $this->getLine();
            $this->msgList=[];
        }
        public function cursorMove( int $x  , int $y  ) {
   
            $this->write( $this->cursor->setOffset( $x,$y));
        }
        public function getCountLine(){
            return $this->lastCountLine;
        }
        private function getLine(){
            if(!sizeof($this->msgList)) return 0;
            else{
                $line=0;
                foreach(  $this->msgList as $msg ){
                    for($i=0;$i<mb_strlen($msg->msg);$i++){
                        if(mb_substr($msg->msg ,$i,1) == PHP_EOL) $line++;
                    }
                }
   
                return $line;
            }
        }
   
    }

实例

1. 直接输出带效果的文字

   // 实例化console类$c = new Console\Console();// 向console类里添加文本$msg = $c->write('this is a test msg.'.PHP_EOL);// 文本设置效果$msg->color('red')->bg('darkGreen')->highLight()->underLine();// 再次添加一个文本$msg2 = $c->write('this is another  msg.'.PHP_EOL);// 文本设置效果$msg2->color('yellow')->bg('purple')->twinkle()->underLine();// 输出文本$c->dump();

   截图：
2. 通过table标签标记输出文本

     /*
    table标记注意事项
    1. 标签有且有table、tr、td，且表桥闭合
    2. table、tr、td标签属性可设置color、bg、twinkle（等文字效果）、width、align。目前只实现了这些
    3. 数据的动态展示原理是通过计算table的行数并移动光标达到的，并不是很严谨，效果也一般
