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();

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){
- $html='
- <table align="right">
- <tr color="red">
- <td width=20 >英文</td>
- <td width=30>数字</td>
- <td width=30>中文</td>
- </tr>
- <tr>
- </tr>
- ';
- for($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 >测试</td>
- </tr>';
- }
- $html.='</table>';
- // 移动光标
- $c->cursorMove(-1000,-($c->getCountLine()));
- // 通过table标签实例Table类
- $t = new Table($html);
- // 输出解析后的table标签
- $c->table($t->table);
- sleep(2);
- }
