Find whole word at beginning of string with preg_match?

Question

I am trying to find whole words e.g. 'Location:', 'Contact:', at the beginning of a string with preg_match.

Please could someone provide and quick example.

Answer 1

starts (^) with word character (\w) and has one or more of them (+) and should be captured and stored in $matches (brackets)

$in = "First word is captured";
preg_match("/^(\w+)/",$in,$matches);
echo $matches[1];
