[pedroz]

$string="google=12 yahoo=publish bing='ok' ask=0";

how get the following from the $string?...
echo $google; output 12
echo $yahoo; output plublish
echo $bing; output 'ok'
echo $ask; output 0

Umm, that doesn't seem like a good idea, since you either don't know what is assigned to $string in the first place (user input), or you do know what's assigned here in the first place, and might just as well do

$google = 12

in the first place.

If it is user input, what you ask for can be done, but why not simply

$array = explode(' ', $string);
foreach($array as $element) {
	echo substr($element, strpos($element, '=') + 1) . '<br/>';
}

You could also do something like:

$engine = array();

foreach(explode(' ', $string) as $data) {
    list($name, $value) = explode('=', $data);
    $engine[$name] = $value;
} unset($name, $value);

Note that I wrapped all of the values in an array, $engine, to avoid the possibility of variable collision in case this is user-supplied data.
