Lionel F. Lebeau

This class can extract all words from string excluding stop words.

It can take a given text string and extracts the list of all words it contains to a array.

An optional list of stop words may be provided to be excluded from the list of words to return.

The class may lower the case of the words to consider words with upper and lower case letters the same.

Prize: One ebook of choice by Packt		 PHP provides an extensive set of functions to manipulate text strings including several ways to split a string into its words.

However, there is no built-in way to detect and exclude stop words.

This class can extract the words of a text excluding stop words. I can also consider words that may appear duplicated but with different case.

Example

<?php
// français
//$text = "Un été à Quibron.";
//$stopwords = array('un','à');

// anglais avec apostrophe et I dans les deux casses
//$text = "Now in 2016, it's 12:28. I am mikel and i from USA";
//$stopwords = array('a','I','the');

// anglais multilignes
/*$text = "After having owned the BMW X3, the MDX is a pleasure to drive.
 Reliability is great for 25,000 miles. Only things wrong are Bluetooth; rings and cannot hear whose on the other end and many viable addresses do not show up on Navigation system.
 Dealer service excellent.
 A few miss-steps in design; no lights for A/C controls at night; rear view pic doesn't come on in reverse for 10 seconds, some wind noise, transmission can be rough and erratic. No ipod plug which I didn't realize until after I purchased. Front end design could be improved, very masculine.
 Sounds like a lot but I do really like this car.
 Also test drove BMW X5 and Lexus 400.";*/
//$stopwords = array('a','I','the','no');

// chinois
/*$text = "????????????????????????????????????????????????????????

????????

?????";*/
//$stopwords = array('?????','???');

// arabe :
//$text = "???? ?? ???.";
//$stopwords = array('??');

// hébreux :
//$text = "???? ??? ???.";
//$stopwords = array('???');

// allemand :
//$text = "Können Sie mir helfen Über das? ";
//$stopwords = array('über');

$getwords = new get_words($text,$stopwords,true);
$words = $getwords->getWords();
//var_dump($words);
if(PHP_SAPI != 'cli'){
    print '<pre>';
    print_r($words);
    print '</pre>';
}else{
