PHP get_meta_tags() Function truncates results -


i trying fetch website keywords get_meta_tags() function. returns truncated results. how can full results?

it gives me mycode --- > 

print_r(get_meta_tags('https://www.youtube.com/watch?v=__dtmkodoyu'));

result --- >

[keywords] => play doh, hello kitty, hello kitty (fictional character), kinder, kinder surprise (consumer product), kinder surprise eggs, peppa pig, peppa pig kinder surpr...

after amount of characters puts dot dot dot. want full.

get_meta_tags() returning sees on page. if "view source" on page, you'll find it's truncated there too:

<meta name="keywords" content="play doh, hello kitty, hello kitty (fictional   character), kinder, kinder surprise (consumer product), kinder surprise eggs,   peppa pig, peppa pig kinder surpr...">

if want all of tags video, you'll need find way of retrieving them (e.g, using youtube api). aren't present in "keywords" meta tag.
