与MySQL连接的PHP连接数的上限是多少？

Question

Is the upper limit of the number of connections for the PHP connection database to be placed in the expansion module? Or by the MySQL database itself is determined by the upper limit of the connection.

Asking because the PHP language is not in the code level to build connection pool, so I am very curious about it is how to limit the number of connections, is not and Java in the connection pool is same, in expansion module (PDO MySQL or mysqli) in limiting the maximum number of connections.

Answer 1

Limit the number of connections your webserver or php-fpm can handle to less than mysql max_connections setting.
Or raise mysql max_connections setting above the number of connections that your webserver can handle.
