使用通配符调用爆炸数组中的所有字符串编号

Question

After you explode a string, you can call the individual delimited words using something like:

$string[0]
$string[1]

etc.

Is there a way to call them all at once with a wildcard. I know this example doesn't work but something like this:

$string[*]

It's probably a dumb question; I'm just trying to save myself having to do 30 lines of code instead of one.

-- EDIT --

Here's what I have right now that's working for me:

$words = explode(' ',$string);
$thestuff = '';
if ($words[0] || $words[1] || $words[2] || $words[3] || $words[4] || $words[5] || $words[6] || $words[7] || $words[8] || $words[9] || $words[10] || $words[11] || $words[12] || $words[13] || $words[14] || $words[15] || $words[16] || $words[17] || $words[18] || $words[19] || $words[20] || $words[21] || $words[22] || $words[23] || $words[24] || $words[25] || $words[26] || $words[27] || $words[28] || $words[29] || $words[30]){
    $thestuff = do_shortcode($content);
}
return $thestuff;
}

But I'd like to be able to do it with $words[wildcard] or something simpler.

You can use this code. You are using OR conditions so that you don't need to check every index.

$words = explode(' ',$string);
$thestuff = '';
if (isset($words[0]) && !empty($words[0])){
    $thestuff = do_shortcode($content);
}
return $thestuff;
}
