Topic: HTTP Download from website?

[primetch]

How can a PHP-based website download pages off of other websites (news-related websites, for example) and store them in a temporary location, retrieving part of the file and displaying it within a page?

I did a quick search for HTTP get but didn't get any results. (I programmed AutoIt before PHP, if that's any help.)

You can simply fetch files into a variable using file_get_contents().

Pretty much all of the function for handling local files will work with remote files too. Here is an example :

Code: [Select]

<?php
  function getTitle($url) {
    $expire_time = 15 * 60; //15 minutes
    $temp_file = '.tmp_'.md5($url); //Make unique filename

    //Check cache
    if(is_file($temp_file) && filemtime($temp_file) + $expire_time > time())
      return file_get_contents($temp_file);

    //Get contents
    $contents = file_get_contents($url);
    
    //Find title
    if(!preg_match("/<title>(.+)<\/title>/",$contents,$matches))
      return false;
      
    //Update cache
    file_put_contents($temp_file,$matches[1]);

    return $matches[1];
  }
  print getTitle("http://www.phpfreaks.com/forums/index.php");
