文字的各種效果標記寫法
字型顏色與背景色
\033[30m 至 \33[37m 設定前景色 \033[40m 至 \33[47m 設定背景色 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; 文字背景顏色範圍: 40:黑 41:深紅 42:綠 43:黃色 44:藍色 45:紫色 46:深綠 47:白色 文字顏色: 30:黑 31:紅 32:綠 33:黃 34:藍色 35:紫色 36:深綠 37:白色
標記閉合
所有效果在文字結尾處要加上閉合的標記:\033[0m;
文字高亮等其他效果
\033[1m 文字高亮 \033[4m 下劃線 \033[5m 閃爍 \033[7m 反顯 \033[8m 消隱
多種效果組合使用
多種效果組合使用時用英文分號隔開,例如藍底紅字下劃線加閃爍 echo "\033[44;31;4m this is a test msg \033[0m".PHP_EOL;
游標的移動與設定
- 移動
\033[nA 游標上移n行 \033[nB 游標下移n行 \033[nC 游標右移n行 \033[nD 游標左移n行
- 設定
\033[y;xH設定游標位置 \033[2J 清屏 \033[K 清除從游標到行尾的內容 \033[s 儲存游標位置 \033[u 恢復游標位置 \033[?25l 隱藏游標 \033[?25h 顯示游標
簡單的實現
文字效果操作類
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; } // 設定文字顏色 public function color( string $c ){ if( isset( $this->colors[$c]) ) $this->style[] = $this->colors[$c]; return $this; } // 設定背景色 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; } // 下劃線 public function underLine(){ $this->style[] = 4; return $this; } // 閃爍 public function twinkle(){ $this->style[] = 5; return $this; } // 反顯 public function rshow(){ $this->style[] = 7; return $this; } // 消隱 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; } } }
游標操作類
namespace Console; // 游標的資訊以及操作 class Cursor{ // 游標設定 \033[y;xH private $x=0; private $y=0; // 獲取游標X軸位置 public function offsetX(){ return $this->x; } // 獲取游標Y軸位置 public function offsetY(){ return $this->y; } // 獲取游標座標 public function offset(){ return [ 'x'=>$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類,通便html的table標記語言,輸出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){ // 解析字串最好 $this->html=$html; $this->parse(); } // 解析字串 將table的每個tr td以及屬性都解析出來 private function parse(){ if( !preg_match("/<table(\s+.*?)?>(.*?)<\/table>/is",$this->html) || !preg_match("/<tr(\s+.*?)?>(.*?)<\/tr>/is",$this->html) || !preg_match("/<td(\s+.*?)?>(.*?)<\/td>/is",$this->html) ){ die('標籤有誤,必須包含table tr td標籤且標籤閉合'); } $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類,輸出自定義的文字或table格式文字
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']); // 顯示問題矯正 $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; } } }
例項
- 直接輸出帶效果的文字
截圖:// 例項化console類 $c = new Console\Console(); // 向console類裡新增文字 $msg = $c->write('this is a test msg.'.PHP_EOL); // 文字設定效果 $msg->color('red')->bg('darkGreen')->highLight()->underLine(); // 再次新增一個文字 $msg2 = $c->write('this is another msg.'.PHP_EOL); // 文字設定效果 $msg2->color('yellow')->bg('purple')->twinkle()->underLine(); // 輸出文字 $c->dump();
- 通過table標籤標記輸出文字
截圖:/* table標記注意事項 1. 標籤有且有table、tr、td,且表橋閉合 2. table、tr、td標籤屬性可設定color、bg、twinkle(等文字效果)、width、align。目前只實現了這些 3. 資料的動態展示原理是通過計算table的行數並移動游標達到的,並不是很嚴謹,效果也一般 */ // 用於隨機字元 $zmstr='abcdefghijklmnopqrstuvwxyz'; while(true){ $html=' <table align="right"> <tr color="red"> <td width=20 >英文</td> <td width=30>數字</td> <td width=30>中文</td> </tr> <tr> </tr> '; for($i=0;$i<5;$i++){ $num = rand(10,99); $color=''; if($num>80){ $color='red'; }else if($num>50){ $color='green'; }else if($num>30){ $color='purple'; } $html.='<tr> <td width=20>'.$zmstr[rand(0,25)].$zmstr[rand(0,25)].$zmstr[rand(0,25)].$zmstr[rand(0,25)].'</td> <td width=30 color="'.$color.'">'.$num.'</td> <td width=30 >測試</td> </tr>'; } $html.='</table>'; // 移動游標 $c->cursorMove(-1000,-($c->getCountLine())); // 通過table標籤例項Table類 $t = new Table($html); // 輸出解析後的table標籤 $c->table($t->table); sleep(2); }
