create a regular expression to match only the first word of a sentence, when it is equal to or greater than 4 characters

I need to create a regular expression to match only the first word of a sentence, when it is equal to or greater than 4 characters. I searched for truth and forums here and could not do it as ..

Example:

"Christmas Baskets"> "Christmas"
"Tea and infusions"> "Tea and infusions"
"Beer"> "Beer"

I'm not sure if I understood the question correctly, but this should give the output you've described:

function get_first_word_or_sentence($sentence)
{
    $word = strtok($sentence, ' ');

    return strlen($word) >= 4 ? $word : $sentence;
}

That's a strange use of RegEx. The following will only match a word at the beginning of a sentence that is longer than 3 characters:

/^[^\s][^\s][^\s][^\s]+/
