Well in your approach you get a bunch of empty elements where the spaces
are. Here are two ways but I'm sure one preg_match_all() without the
explodes and loop could do it (some guru will show us):
//one way
$text = 'xxx xxxx xx xxxxx xx xxx
xx xxxxx x xxx xx xxxxxx
xx xxx xx xxxx xx xx';
$lines = explode(PHP_EOL, $text);
foreach($lines as $line) {
$temp = explode(' ', $line);
$result[] = array_filter($temp, 'reduce');
}
function reduce($var) {
return !empty($var);
}
print_r($result);
//another way
$text = 'xxx xxxx xx xxxxx xx xxx
xx xxxxx x xxx xx xxxxxx
xx xxx xx xxxx xx xx';
$lines = explode(PHP_EOL, $text);
foreach($lines as $line) {
preg_match_all('|([^\s]+)+|', $line, $matches);
$result[] = $matches[1];
}
print_r($result);
