How can I make preg_match_all array

Question

I have this:

$text = $_POST['text'];

When I echo $text I get this:

ggg #hhh #ddd ggg hhhrr ggg #ttt 

When I do this:

$val = preg_match_all("/#\w+/", $text, $matches);
print_r($matches);

I get

Array ( [0] => Array ( [0] => #hhh [1] => #ddd [2] => #ttt ) )

But I want output like this:

Array ( [0] => #hhh [1] => #ddd [2] => #ttt ) 

thanks

Answer 1

Another approach is to use named groups.

$val = preg_match_all("/(?P<myLabel>#\w+)/", $text, $matches);
print_r($matches['myLabel']);

Answer 2

Take the first (zeroth) item from the array by changing this:

print_r($matches);

To this:

print_r($matches[0]);
