PHP - Get All Words From A Page

: : NEW Problem

I want to replace bad words which someone has inputted into my HTML textarea, with something like [CENSORED].
Here's what I've got so far:
note: $review is the posted textarea name.
Code: [Select]

$words_text = 'badwords.txt';
$bad_words = file($words_text);
               
$good_words = str_ireplace($bad_words,'[CENSORED]',$review);
         
echo $good_words;


The thing is, if I type bad words in the textarea, I still get bad words when I echo $good_words.

I don't know why I'm getting this, any ideas

Hello dear friends,

I've an idea so let us say we have paragraph with bad words 

Code: [Select]
$para = "Hello shit oh shit what the hell this is shit day";
Now let say we create textarea

Code: [Select]
<textarea id="badword" name="badword">
</textarea>
and let us say we have database table as following

Code: [Select]
CREATE TABLE `banned` (
 `id` varchar(50) NOT NULL default '',
 `badwords` text NOT NULL,
 PRIMARY KEY  (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

consider we have connetion and can update mysql table badwords

1- now how we can enter word per line in this textarea

example we entered in this textarea per line
shit
hell
die
death

then by click on submit it stored in an database table 'banned' as

INSERT INTO `banned` VALUES ('1', 'shit,hell,die,death');


2- if we called `badwords` from table 'banned' how then can put 'shit,hell,die,death' into array so we can exclude it from $para

 
can someone please help me in this , how to store textarea per line as sperated words in database table and how then call it back as array to exclude it form our paragraph

Or

it there any other simple way doing the same 

thank you

I'm trying to pull in data using a particular word from a mysql db (it's like a search facility).

But this code only picks if the db has got the exact same word.
E.g. if fincom = "DALLS" it pulls the data only when "searchwords" has DALLS. It ignores if "searchwords" has BARBIE DALLS. How can I fix this. I need to pick all records which contains the search word 'fincom' anywhere in  searchwords.

Hope this makes scene.

$SomeVar = $_POST['fincom'];
$query = "SELECT * FROM  news_home WHERE searchwords = '".$SomeVar."' ORDER BY timestamp DESC";
$results = mysql_query($query);

I'm pretty sure the problem is starring me in the face, but I can't seem to locate it.


function filter($string)
{
//swear words pulled from bannedwordlist.com
$f = fopen('../badwords.txt', 'r');
$bad_words = fread($f, filesize('../badwords.txt'));
$bad_words = explode('\n', $bad_words);

$input = strtolower($string);

foreach($bad_words as $value)
{
$string = str_replace($value, '****', $input);
}

return $string;
}


UPDATED CODE

function filter($string)
{
//swear words pulled from bannedwordlist.com
$f = fopen('../badwords.txt', 'r');
$bad_words = fread($f, filesize('../badwords.txt'));
$bad_words = explode('\n', $bad_words);

$input = strtolower($string);
$string = str_replace($bad_words, '****', $input);

return $string;
}


I've already echoed out $value in the foreeach loop, and it does correctly retrieve the bad words and put them into an array. My only problem is, the returned string is still in strtolower() form, and the words aren't censored. :/

Hi there,

I'm making an online clothing store for the brick and mortar shop we have and would like the customer to be able to refine their search by size, colour etc.

The size options will be XS, S, M etc etc where XS is 0, S is 1 and so on. So when they select XS it will add ?size=0 to the URL, if they select XS and S it will be ?size=0;1

What I need to know is how to make some PHP code which can recognise the ; is a break and know that both sizes are selected.

Hope that makes sense and thanks in advance
