Matching strings in txt

[unknown101]

Hi Guys,

 

Im trying to create a script which gets the content of a website and searches it for key terms which are stored in a text file.

 

Now I can get the content and assign it to a variable no problem, but ive been trying for hours on end to loop through the txt file key terms and use them to compare with the $source website. 

 

Ive been using the "Stripos" function i.e.    if ( stripos($source, $keyterm) ) { ..do this... } and it just wont work.

 

Are there any other ways to search for a value within a load of text in PHP?

 

Any suggestions appreciated..

 

Thanks

Maybe we can help with the logic of your code? Mind sharing it? Also, can you give an example of a website and some terms?

 

By looking at your code, we could either diagnose the problem or help you find a better alternative.

I am using a class called "Snoopy", which I downloaded from the net .. I think if you just google snoopy php its one of the first hits (Just useful for fetching web content etc)

 

My code is as follows:

 

<?php

include "Snoopy.class.php";
$snoopy = new Snoopy;

$myFile = "KeyTerms.txt";
$fh = fopen($myFile, "r");
$line = fgets($fh);

$snoopy->fetchtext("http://www.any-domain.com");
            $results = $snoopy->results;

            do
           {
           $names = array("$line");
   
   		foreach ($names as $value)
   			 {
		   echo "Search: $value<BR>";

		   if ( stripos($results, $value) )

		      {
   			     echo The term '. $value .' has been found;
	                   }
                             else
                               {
                             echo No match found<BR>';
                                }
                            }
}
while ( $line = fgets($fh, 1000));	

?>

 

If for example I run this code and have 4 values on seperate lines in a text file which I know are on the site which has been fetched, it will only print to say its found the last value listed in the txt file??  I dont know why its not looping through all values? PLzzzzzzzzzz help,

 

Thanks in advance

Please do not bump your question so quickly. Also, you have asked this same question at least twice before and you should have continued the same thread.

 

As I posted in one of your other threads -- please show use the contents of the file you're reading.

ok Sorry.

 

The keyterms.txt file just literally contains a few words i've been testing with.  Say I scan Google.co.uk, I just add a few words which I know are on that homepage so I can test it, also one which i know isnt.  The file just looks like:

 

Keywords.txt..

 

Google

Images

Maps

ThisIsntOnThere

 

Dont know what else to try:|

 

Thanks

Putting the line of read from the file into an array is useless. Try this:

<?php

include "Snoopy.class.php";
$snoopy = new Snoopy;

$terms = array_map('trim',file("KeyTerms.txt"));
$snoopy->fetchtext("http://www.any-domain.com");
$results = $snoopy->results;

foreach ($terms as $value) {
        echo "Search: $value<BR>";
        if ( stripos($results, $value) )
   	      echo The term '. $value .' has been found;
        else
              echo No match found<BR>';
}
?>
