hi i am trying to write a method to see whether the word 'not' appears before a positive or negative word then i want to +1 to the negative count and -1 from the negative count any idea how to do this, i already a 2 methods which count how many times the positive and negative words appear
// Gets the positive words and check for the word in the text
while($check = mysql_fetch_assoc($pos)){
$lower = mb_strtolower($check['word']);
if(isset($cnt_r[$lower])){
$good+= $cnt_r[$lower];
echo "<p>" . $check['word'] . "</p>";
$review_text = preg_replace("/\b{$check['word']}\b/", "<span class=\"goodword\">{$check['word']}</span>" , $review_text);
}
}
// Gets the negative words and check for the word in the text
while($check = mysql_fetch_assoc($neg)){
$lower = mb_strtolower($check['word']);
if(isset($cnt_r[$lower])){
$bad+= $cnt_r[$lower];
echo "<p>" . $check['word'] . "</p>";
$review_text = preg_replace("/\b{$check['word']}\b/", "<span class=\"badword\">{$check['word']}</span>" , $review_text);
}
}
