creating a word filter

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.

Code:

---

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

---

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

Code:

---

$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...

how bout for those whos host dont use PHP 5?
lol

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?

PHP Code:

---

$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? :p)

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.

koo. Thanks.
Ill try it out.

EDIT - Worked out exactly how i wanted it to.

==============================
= str_replace
==============================

Compability :
==========

works with PHP3, PHP4 and PHP5
Linux and Widnows

Code :
======

<?php

// Provides: You should eat pizza, beer, and ice cream every day
$phrase = "You should eat fruits, vegetables, and fiber every day.";
$healthy = array("fruits", "vegetables", "fiber");
$yummy = array("pizza", "beer", "ice cream");

$newphrase = str_replace($healthy, $yummy, $phrase);

?>

Descriptions :
==========

It replaces word like as given in code above.

http://ca3.php.net/manual/en/function.str-replace.php

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