Using array to replace text

Now, this is a tricky one for me so I hope someone know if there is a solution to this:


I'm currently using this code to search an array for a word and if found replace that word with ****. Now, can I use an array to specify both the bad word AND a word to replace it with?

My current code:

function find_replace_happy ($word){

$badwords = array(

0 => 'badword',
1 => 'badword',
2 => 'badword',
3 => 'badword',
4 => 'badword',
5 => 'badword',
6 => 'badword',
7 => 'badword'

);


$word = str_replace($badwords,'****', $word);
return $word;
}

Maybe like this:
function find_replace_happy ($word){

$badwords = array(

0 => 'badword',
1 => 'badword',
2 => 'badword',
3 => 'badword',
4 => 'badword',
5 => 'badword',
6 => 'badword',
7 => 'badword'

);

$goodwords = array(

0 => 'goodword',
1 => 'goodword',
2 => 'goodword',
3 => 'goodword',
4 => 'goodword',
5 => 'goodword',
6 => 'goodword',
7 => 'goodword'

);

$word = str_replace($badwords,$goodwords, $word);
return $word;
}


(At least, I think that'll work).

You mean like this:


function find_replace_happy ($word){

$badwords = array(

0 => 'test',
1 => '****',
2 => 'badword',

);

$goodwords = array("happy", "sad", "yummy");

for ($i=0; $i<=count($badwords); $i++)
for ($j=$i; $j<=$i; $j++)
$word = str_replace($badwords[$i],$goodwords[$j], $word);
return $word;
}

ah I didn't know that str_replace can take the array index automatically without looping.

Yes, it can. However the methods described are not what you want.

Your original code that you posted should work.

When str_replace is fed an array of searches, and a string to replace with it will use that for every entry it finds in the search list.

From the manual: "If search is an array and replace is a string, then this replacement string is used for every value of search."


function find_replace_happy($word) {
$badwords = array(
0 => 'badword',
1 => 'badword',
2 => 'badword',
3 => 'badword',
4 => 'badword',
5 => 'badword',
6 => 'badword',
7 => 'badword'
);

return str_replace($badwords, '****', $word);
}

Thank you, got it to work :)

BonRouge's code is a thing-a-beauty if you want to customize the replacement words so I wouldn't say it's not what you want.

Example replacement words:

farg
shizniz
durn
gull durn
fuzzy
heck
wench
kitty
son-of-unwed-mother
rooster
