You can use str_replace, A really simple function and can simply replace 'groups' with 'organizations', and 'group' with 'organization', retaining the plural syntax.

$phrase  = "Organizations you own, Your organizations, Create a new organization";
$old = array("group", "groups");
$new   = array("organization", "organizations");

$newphrase = str_replace($old, $new, $phrase);
echo $newphrase; //Should be what you want it.

A way to take care of the casing:

 

<?php
$str = 'Groups you own
Your groups
Create a new group';
function _callback($matches) {
$matches[0] = 'organization';
if (ctype_upper($matches[1])) {
	$matches[0] = ucwords($matches[0]);
}
return ($matches[2] ? $matches[0] . 's' : $matches[0]);
}
$str = preg_replace_callback('~\b(g)roup(s?)\b~i', '_callback', $str);
echo $str;
?>

Slick solution, thebadbad

 

Got me thinking of an alternative one without the need of captures:

 

$str = 'Groups you own
Your groups
Create a new group';

function _callback($matches){
    $replace = (ctype_upper($matches[0][0]))? 'Organization': 'organization';
    return (substr($matches[0], -1, 1) == 's')? $replace . 's': $replace;
}

echo $str = preg_replace_callback('#\bgroups?\b#i', '_callback', $str);

Granted, this feels like a violation of DRY by replicating the word 'organization' twice in essence (could also be troubling in the event of a typo with one of the conditions). An alternative callback could then be:

 

function _callback($matches){
    $replace = 'organization';
    if(ctype_upper($matches[0][0])){
$replace = ucfirst($replace);
    }
    return (substr($matches[0], -1, 1) == 's')? $replace . 's': $replace;
}

 

As usual, so many ways to solve a problem. At first glance, I was confused by your regex pattern (the captures threw me off initially).. wasn't until I examined your callback that I understood

I think this would be a really nice candidate for a closure in PHP 5.3, something along the lines of :

 

function create_callback($replace) {
return function ($match) use ($replace) {
	if (ctype_upper($match[0][0])) {
		$replace[0] = strtoupper($replace[0]);
	}
	return $replace;
};
}

echo $str = preg_replace_callback('/\bgroup(?=s?\b)/i', create_callback('organization'), $str);

 

I also changed the regular expression so that the callback doesn't need to take care of pluralising.

Yet another slick solution ( good one salathe ) I particularly like the lookahead assertion dealing with the [optional s] and word boundery - as you said, doesn't need to take care of pluralsim. Bonus points for you. With all these solutions flying around, you'd think the holiday giving season is here or something. 

 

We could even base your solution on PHP 5.2.x:

 

function _callback($matches, $replace = 'organization'){
    if(ctype_upper($matches[0][0])){
$replace[0] = strtoupper($replace[0]);
    }
    return $replace;
}

echo $str = preg_replace_callback('/\bgroup(?=s?\b)/i', '_callback', $str);
