PHP simultaneously extracts text from multiple news examples _php tutorial

This article is a small program to extract text from a batch of news pages, which can save the content of each piece of news as a text file with the title of the news as the file name. If you have a better approach, please contact me:

Here is an example of the news under "Today's headlines" in the net.
($url)? "": $url = "http://www.unn.com.cn/GB/channel2/3/11/index.html"; Today's News
if (Isset ($url) && $url! = "") {
$str = Implode ("", File ($url));
$str _ary = Explode ("

", $STR);
$str _ary = Explode ("
• ", Trim ($str _ary[1]));
  for ($i =0; $i <8; $i + +) {
  if (strlen (Trim ($str _ary[$i)) <3) {
  Continue
  }
  echo "News". $i. " : ". $str _ary[$i];
  $str 1=strstr ("$str _ary[$i]", $str 2=strstr ("$str _ary[$i]", "target";
  $len 1=strlen ("$str 1");
  $len 2=strlen ("$str 2");
  $len = $len 1-$len 2;
  $url =substr ("$str 1", Ten, $len-10);
  if (strlen (Trim ($url))!=0) {
  $url = "http://www.unn.com.cn/". $url;
  Define (Contents_dir, "./contents/");
  if (Isset ($url) && $url! = "") {
  $str = Implode ("", File ($url));
  $str 1=explode (, $str); Remove the upper part of the file that is useless
  $str 2 = Explode (
  , $str 1[1]);
  Take out the lower half of the file and remove the bottom half of the paper, and all you get is useful.
  $str 3=explode (, $str 2[0]); Remove the file title and body from the entire useful section
  $str 4=explode (, $str 2[0]); Date and time taken out
  $str 5=explode (, $str 3[1]); Remove title from title and body section
  $title =str_replace ("
  "," ", $str 5[0]);
  $str 3=explode (
  , $str 2[0]); Remove the body of the file from the entire useful section
  $str 3[1]=str_replace (
  , "". ", $str 3[1]);
  $str 3[1]=str_replace (, "", $str 3[1]);
  $str 3=strip_tags ($str 3[1]);
  $PF =trim ($title). ". TXT ";
  $PPF =fopen (Contents_dir. " $pf ", W);
  Fputs ($PPF, $title);
  Fputs ($PPF, "$str 4[0]");
  Fputs ($PPF, $str 3);
  }
  }
  }
  }
  ?>
