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 ){

$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){

}
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';

<tr color="red">
<td width=20 >英文</td>
<td width=30>数字</td>
