    fopen() with url and search engine (beginner)

    Dear group,



    When I went through the php docs I come across with fopen() function
    which can also takes the any url. So I tested with this following little
    code.



    <?php

    $fh =
    fopen("http://www.google.co.i n/search?hl=en&q= php&btnG=Google +Search&meta=",
    "r");



    while(!feof($fh ))

    {

    $output = htmlspecialchar s(fgets($fh, 1024));

    echo ("$output<br />");

    }



    fclose($fh);



    ?>



    The query string does that all. If I want to have my own page with a text
    box and a submit button which searches the google and display those google
    search result links in my web page. Can that be possible? Is this the basic
    thing about search engine? Or I am I missing something very basic? Thanks
    for any help.

      You need to set the 'q' var in the query string you pass to google.com.

      In your page.php:

      ....
      <form action="page.ph p" ... >
      <input name="str" type="text" />
      <input type="submit" value="Search" />
      </form>

      <?php
      if (isset($_POST['str'])) {

      $str = $_POST['str'])
      $fh = fopen('http://www.google.co.i n/search?q=' . $str, 'r');
      ...
      fclose($fh);

      }
      ?>

      However, if you have already sent any html (eg. that <form>) you should
      not print out again the <html>, <head>, <body>, etc, html tags coming
      from google.co.in. You should strip them out. Take a look at file() or
      file_get_conten ts() or, better, see <http://www.google.com/apis/>.

              Why should they? It works fine for them.
