I have a .txt
file with a list of 60,000 English words. I wanted to insert those to my database, so I simply just did as show here.
$file = new SplFileObject('list.txt');
foreach ($file as $line => $word) {
$p = new PDO('mysql:host=localhost; dbname=test_dictionary', 'root', 'test');
$p->query("INSERT INTO words (english) VALUES('$word') ");
}
Now, after I run this script, I get the following error:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [1040] Too many connections' in /var/www/skillz/test/curl/index.php:17 Stack trace: #0 /var/www/test/index.php(17): PDO->__construct('mysql:host=loca...', 'root', 'test') #1 {main} thrown in /var/www/test/index.php on line 4
That line 4
is where the new PDO('mysql:')
is located. So, I tried to search this error, and found this answer that seemed a solution. And I edited mysql accordingly, as
$ vi /etc/my.cnf
max_connections=250
But I still get the same error, I have MySql 5.5.38
running PHP-FPM, NGINX in CentOS 6.5
