How to get the words that start with '#' in string using php?

Question

I have this sentence

"My name's #jeff,what is thy name?"

And now i want to get #jeff from this sentence. I have tried this code

for ($i=0; $i <=substr_count($Text,'#'); $i++) { 
    $a=explode('#', $Text);
    echo $a[$i];
}

But it returns #jeff,what is thy name? which is not what my soul desires

Answer 1

There is simpler solution to do it. Use preg_match() that find target part of string using regex.

preg_match("/#\w+/", $str, $matches);
echo $matches[0]

Check result of code in demo

If you want to get all matches string, use preg_match_all() that find all matches.

preg_match_all("/#\w+/", $str, $matches);
print_r($matches[0]);
