I'm running a RegEx to match all instances of the Twitter hashtag. It returns it just fine, but now I just want to loop through the first set and return my #hello, #world, #hello-world
, not the second set.
Array
(
[0] => Array
(
[0] => #hello
[1] => #world
[2] => #hello-world
)
[1] => Array
(
[0] => hello
[1] => world
[2] => hello-world
)
)
Specify $arr[0]
as the array you want to iterate:
foreach ($arr[0] as $tag) {
// …
}
