PHP remote access to Web content

1. Intercepting a PHP class file mainly involves getting the HTML content of the URL and then making it from the HTML content Regular ExpressionsThe

Include ' stringbuilder.php '; class Cutpage{function __construct () {}//method One: Connection gets the text content of the whole file function getallcontent ($url) { $resouce =fopen ($url, "R") or Die ("File open failed!") if (! $resouce) {echo "Request file does not exist!) ";} $ALLC//length is too short to be used for stringbuilder$sb=new StringBuilder (), while (!feof ($resouce)) {//if not to the end of the file $line= Fgets ($resouce, 4096); $SB->append ($line);} Fclose ($resouce); return $SB->tostring ();} Method Two: Get all the text to match the text title---------format: xxxx (xx) XXX form expression function matchcontenttitle ($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  $array [1];} Else{echo "Match failed! ";}} The matching section returns the ArrayFunction Matchcontentchapter ($content, $regex _chapter) {if (Preg_match_all ($regex _chapter, $) that carry the chapter. Content, $matcher)) {return $matcher [1];} Else{echo "Match failed! "; return;}}}

Test PHP files

Include ' cutpage.php '; class Test{publicstatic function  start ($url, $regex _title, $regex _chapter) {$cut =new Cutpage (); $all = $cut->getallcontent ($url); $returnTitle = $cut->matchcontenttitle ($all, $regex _title); echo " Title: ". $returnTitle; $arrays = $cut->matchcontentchapter ($all, $regex _chapter); for ($i =0; $i
 
   
  Regular Expressions $regex_title= "/\s*[<]div id=\" title\ ">[<][h][1]> (\s+) [<]\/[h][1]>[<]\/div>\s*/]; $ regex_chapter= "/\s*[<]a href=\" \d{7}[. Html\ "[\w+] [<]\/a>\s*/";//chapter Test::start ($url, $regex _title, $regex _chapter);//echo "cut". $return;// The
  Regular expression
 of matching Chinese characters ^[\u4e00-\u9fa5]+

This builds a StringBuilder class similar to Java

Class stringbuilder{    const line= "
";    Protected $list = Array (");        Public function __construct ($str =null)    {        Array_push ($this->list, $str);        }        Public function append ($str)    {        Array_push ($this->list, $str);        return $this;    }    Public Function Appendline ($str)    {        Array_push ($this->list, $str. self::line);        return $this;    }    Public Function AppendFormat ($str, mixed $args)    {        Array_push ($this->list, sprintf ($str, $args));        return $this;    }    Public Function toString ()    {        return implode ("", $this->list);    }    Public Function __destruct ()    {        unset ($this->list);}    }  

The above describes the PHP remote access to Web content, including the regular expression of content, I hope the PHP tutorial interested in a friend to help.
