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

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

标记闭合

  所有效果在文本结尾处要加上闭合的标记:\033[0m;

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

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 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
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

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;
    }
}
 }

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 = 'D';
    else $dx = 'C';
    if($this->y<0)$dy = 'A';
    else $dy = 'B';
    $absx = abs($this->x);
    $absy = abs($this->y);
    return "\033[{$absx}{$dx}\033[{$absy}{$dy}";
}
 }

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('标签有误,必须包含table tr  td标签且标签闭合');
    }

    $this->table['html'] = $this->html;
    $this->getPrototype('table',$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['tr'] = $trList[0];
  foreach($this->table['tr'] as $k=>$tr){
 $this->table['tr'][$k] = [];
 preg_match_all("/<td(\s+.*?)?>(.*?)<\/td>/is",$tr,$tdList);
 $this->table['tr'][$k]['td'] = $tdList[0];
 $this->table['tr'][$k]['html'] =$tr;
 $this->getPrototype('tr',$this->table['tr'][$k]);
 foreach ($this->table['tr'][$k]['td'] as $kk=>$td){
$this->table['tr'][$k]['td'][$kk] = [
    'html'=>$td,
    'content'=>$tdList[2][$kk]
];
$this->getPrototype('td',$this->table['tr'][$k]['td'][$kk]);
 }
  }
   }else{
  die('Tr 不存在');
   }
    }else{
   die('Table 不存在');
    }
}
private function getPrototype(string $tag,&$v){
    preg_match("/<{$tag}(\s.*?)?>(.*?)<\/{$tag}>/is",$v['html'],$arr);
    if(strlen($arr[1])){
   $arr2 = explode(" ", trim(preg_replace("/( +)/is"," ",$arr[1])));
   foreach ($arr2 as $arr3){
  $arr4 = explode('=',str_replace([' ',"\"","\'"],'',$arr3));
  if(in_array($arr4[0],$this->props)){
 $v[$arr4[0]] = $arr4[1];
  }
   }
    }
}
 }

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 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: 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
 */
  // 用于随机字符
 $zmstr='abcdefghijklmnopqrstuvwxyz';
 while(true){
$html='
    <table align="right">
    <tr color="red">
   <td width=20 >英文</td>
   <td width=30>数字</td>

for($i=0;$i<5;$i++){
