you need to explode the paragraph by fullstop. lets say your full paragraph is store in $str

$lines_arr = explode(".",$str);

now $lines_arr is an array contains numbers of lines.

now under loop you can check which lines contains "thanks" , if it is then skip it.

    $string = '';
    for($i=0; $i<(count($lines_arr)-1); $i++){
     //with the help of strpos
         if(strpos($lines_arr[$i],"Thanks") == false){
             $string .= $lines_arr[$i].". ";
       }
}

you can use str_replace

echo str_replace("Thanks", "", "This is very nice. Thanks for your support.");
# Output: This is very nice.  for your support.

This would remove the single word, not the sentence that the word appears in.

you are not understanding my problem. I can do this very easily but I dont want the whole sentance that contains the word "Thanks".

If you expect proper punctuation, you could explode() the string into an array on the full stops and delete the elements with your particular word, then merge all the elements back into a string.
