Why are there no results from the database?

Question

PHP

$result = mysql_query("SELECT * From arajin_models WHERE name LIKE '%f%' ") or die(mysql_error()); ;
$row = mysql_fetch_array($result);
print_r($row);

there is nothing if
echo $result;
then
Resource id #4

Answer 1

Made it a little easier, found an error. May be useful to someone:

elseif(preg_match("#[a-z]+#ui", $login) && preg_match("#[а-я]+#ui", $login)) msg('Логин должен состоять только из русского или английского алфавита');

Answer 2

Forgot the letter "yo", forgot to set the flag "u"? Try . preg_match('|^[a-zа-яё0-9]+$|ui', $login)

Answer 3

So the query returned 0 rows.
print_r(false) doesn't output anything, so it's better to use var_dump

Answer 4

Manual: the resource variable type
mysql_fetch_array will return false if the fetch from the database is empty
