Refreshing until word found..

yeahoo7

i'd like to make a script that refreshes a certain page on your browser and stops refreshing the browser when a certain word is found..

is it possible?
how would i do it?

yes it is possible !!

Sounds like when you refresh the content of the page is changing means your server side script is generating new content from Database or from other source.

So you have to check for that perticular word when you are
showing in the page. if not found send a tag like

echo "<meta Refresh="$PHP_SELF;10">"

I hope it will help you !!

thanks.. can you guide me how to fetch data from a webpage and search a certain word you want?

srikanth1184

you won't fetch data from a webpage. you will fetch data from a database and include in html file.

To search certain word in a string you can use preg_match() function. see www.php.net for more info about preg_match()

i made so it checks the html to find a word from a webpage..

but i can't figure out how to refresh that same original page simultaneously as the script reads.

ideas?

well to refresh the page use

echo "<meta Refresh="$PHP_SELF;10">"

the structure of you prog should be like this

  code that generates data from DB 

  $found =  boolean ( try to find the word you wanna search ) ;

   if ( $found)
   $meta = "";  // no refresh
   else
   $meta = "<meta Refresh=$PHP_SELF;10>" ; //refresh

<html>

 <?  echo $meta  ?>

</html>

Hope you will get it !!

I can figure out that part, just like what you did.

but i have problem making a whole different page refresh at the same time.

the page im finding a word from, isn't my script.

let's say i'm searching CNN.com frontpage for a word "PHP".
my script will refresh the original CNN.com webpage in the other page or, frame until that word is found.

how would i do that?

ohh :o !!

I see what you mean !! I am eager to know the answer !!

That would require javascripting, but i'm not sure exactly what you'd need. Why don't you go the other way though? When you refresh php_self, open the page you want from the server, using fopen, and check the output for the word you're looking for. If it's there, don't refresh. That would be much faster, and you wouldn'thave to worry about people who turn js off 🙂

You don't have to refresh, Just fgets into a variable and search for it there.

this is the script i made...

<?php

$GrabURL = "http://www.picrave.com/versus.phtml?gender=1";
echo '
<IFRAME
SRC="
';
echo $GrabURL;
echo '
"
WIDTH=600 HEIGHT=400
ALIGN=CENTER
NAME="content"
FRAMEBORDER=0
>
</IFRAME>
';

$OpenFile = fopen("$GrabURL", "r");
$RetrieveFile = fread($OpenFile, 200000);

if(preg_match("/Germany/i", $RetrieveFile)) {

echo 'found!';

}
else {

echo '<meta Refresh="$PHP_SELF;10">';

}

echo $RetrieveFile;

fclose($OpenFile);

i used echo to see if the one im searching for is exactly same as the one i'm seeing. but it isnt. i'd like to see the "original page"(like in the frame) which script used to search.

any solutions?
