如何确定字符串中的某些单词是否大于50个字符？

Question

How to do such thing in PHP? I have fond on this forum only solution for C# How to check if a string contains a word longer than 50 characters?

E.g. I have a string:

$string_to_check = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa rrrr fe we we hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhererererereerdfsdfsdfsdfsdfsdfsdfsdfsdfsdfttttfsd hhghhhhhhhhhhhhhhhhhh fd s hoefjsd k
bla bla bla";

And I want to make an if condition so when string contains a word that is 50 or more characters long return false; else return true;

Any advice how to solve this is appreciated.

Answer 1

try this function:

function not_long_word($sentence, $length = 50) {
    $words = explode(' ', $string);
    foreach ($words as $key => $value) {
      if (strlen($value) > $length) return false;
    }
    return true;
}

usage:

$text = "word wooooooooooooooooooooooooooooooooooooooooooooooooooooooooooord";
if (not_long_word($text)) {
    echo "there no word longer than 50!";
}
