hi folks, i have a variable in which some common words are stored and another variable in which a sentence is stored. I want to remove the common words from the sentence> Is there any way of doing this in PHP?
Code: [Select]
<?php
$common_words = "to, this, all, the, from";
$sentence = "I want to remove all the common words from this sentence";
?>the final output should be:
"I remove common words sentence."

My current code (which works):

Code: [Select]
<?php

$body = explode("\n", $body);
$body = array_slice($body, 3);
$body = implode("\n", $body);

?>

Is there a better way of doing this, so I dont have to explode and implode an array just to accomplish this?

Extremely new here and to PHP and I have exhausted my newbie resources and my brain on this one.   

Concept: Cron Job to INSERT 5 lines per hour (Not the whole list at once)
Script to read a pipe delimited text file (about 5k Lines) Open File Get last (bottom) 5 lines of file, ignore the rest Insert those 5 lines into my database Open File, Remove last (bottom) 5 lines
I am able to do parts 1-3 but not part 4 (removing last 5 lines) Please help me!

Code: [Select]
$data = array_slice(file('data.txt'), -5);
foreach($data as $value)
 {
  $fields=explode("|",$value);
  $num=count($fields);
  for ($n=0;$n<$num;$n++)
   {
    $null="";
    print ($n==0) ? "Importing Video...<BR>" : $null;
   }

// Insert into tmpvideos table here
include("includes/config.php");
            $last_id_result = @mysql_query( @"SELECT ext_id FROM tmpvideos ORDER BY ext_id+0 DESC, id DESC" );
            if ( 0 < @mysql_num_rows( $last_id_result ) )
            {
                $last_id = @mysql_result( $last_id_result, 0, "ext_id" ) + 1;
            }
            else
            {
                $last_id = "1";
            }


            copy($fields[3], "thumbs/ex_".$last_id.".jpg" );
            $fields[3] = "thumbs/ex_".$last_id.".jpg";

set_time_limit(0);
mysql_query("INSERT into tmpvideos (id, ext_id, title, description, duration, category, date_added, thumb, video, views, rating, votes, status)
VALUES ('','".$last_id."','$fields[0]','$fields[1]','$fields[5]','$fields[6]',NOW(),'$fields[3]','$fields[2]','','','','1')");

 }

I understand the 'concept' but am unable to grasp the code! I have tried many snippets and really need help.
