creating a word filter

[PlaGuE]

I cant seem to make it so that when it searches for a word... it doesnt care about the 'caSe'.


I looked on PHP.net cuz i remembed seeing sumtin about it in an example. but....


Oh and google wasnt my friend when i searched for it.

[bearruler]

$newphrase = str_replace($old, $new, $text);

For example, If you wanted to replace all commas with spaces...

$text = "Hey,this,is,an,example";
$text = str_replace(",", " ", $text);
//$text would equal "Hey this is an example"

I hope this is what you needed

thanks for the reply. But thats not what i meant.
Im sorry for "implying my question" in a "vague" way. I do that sumtimes.

If you read my first line carefully you'll understand my question.
If Not Read on.

I cant seem to make it "not Care" about CaSe.


As in. If theres a word like Homo.(Example). It doesnt matter what the case of the word is. it will still be replaced.

Example:

Homo
HoMo
HOMO
hOmO
hOMO
etc...etc.. etc...

cuz str_ireplace(); doesnt even "change color" in the editor.
nor does it work when run.

Crikey, how can that not exist in PHP 4?

$string = 'The quick brown fox jumped over the lazy dog.';
$patterns[0] = '/(?i)Quick/';
$patterns[1] = '/(?i)Brown/';
$patterns[2] = '/fox/';
$replacements[2] = 'bear';
$replacements[1] = 'black';
$replacements[0] = 'slow';
echo preg_replace($patterns, $replacements, $string); 

Just a modified example from PHP.net, http://au2.php.net/preg_replace

This is the other way that I've found (haven't searched hard though, so perhaps someone has a better way? )

The patterns are the things your searching for, replacements, whats to replace it with, and the (?i) makes it case insensitive, so it needs to be included.

EDIT - Worked out exactly how i wanted it to.

But str_replace is case sensitive, which isn't what hes after.
