PHP remotely obtains web content

1. Intercept the php class file, which mainly includes obtaining the html content of the url and then matching

	include 'StringBuilder.php';
	class CutPage{
		function __construct(){
		}
		
		//方法一：连接 获取真个文件的文本内容
		function getAllContent($url){
			$resouce=fopen($url, "r") or die("文件打开失败！");
			if(!$resouce){
				echo "请求文件不存在！";
			}
			//$allc//长度太短了取不全用自购建的stringbuilder
			$sb=new StringBuilder();
			
			while(!feof($resouce)){
				//如果没有到文件的结尾则继续向下执行
				$line=fgets($resouce,4096);
				$sb->append($line);
			}
			fclose($resouce);
			return $sb->toString();
		}
		//方法二：获取所有的文本进行文本title的匹配---------格式为：xxxx(xx)xxx的形式表达式	
		function matchContentTitle($content,$regex_title){
			//echo "regex:".$regex_title;
			if(preg_match($regex_title, $content)){
				$array=preg_split($regex_title, $content,-1,PREG_SPLIT_DELIM_CAPTURE);
				return  $array[1];
			}else{
				echo "匹配失败！";
			}
		}
		//匹配章节 返回携带章节的array
		function matchContentChapter($content,$regex_chapter){
			if(preg_match_all($regex_chapter, $content,$matcher)){
				return $matcher[1];
			}else{
				echo "匹配失败！";
				return ;
			}
		}
		
	}

with regular expressions from the html content. The above introduces PHP to remotely obtain web page content, including regular expressions. I hope it will be helpful to friends who are interested in PHP tutorials.
