Project structure:

The strategy mode follows the open close principle to achieve code decoupling. It is also convenient to extend the new method. Just inherit the policy interface. These two points listed above are the advantages of the policy mode, but they are not perfect. There are still many shortcomings that we need to master and understand.
The policy pattern distinguishes the object itself from the operation rules, so our entire pattern is also divided into three parts.

• Context: the context used to operate the policy, that is, we tourists.
• Abstract strategy class: the abstraction of strategy and travel mode
• Concrete Strategy: specific strategy implementation, specific implementation of each travel mode.

MySQL allocates the connection buffer and the buffer sent by the result set for each client connection. The connection buffer is mainly used to accept the sql statements sent by the client, and the initial allocation size is net_buffer_length , can grow dynamically, and can reach max_allow_packet size. This parameter is session read-only. The implication is that the new connection takes effect only when it is modified globally. max_allow_packet It is a parameter used by MySQL to control the size of network packets. The default value is 4M. Once, you can control the large size of a MySQL query statement to achieve MySQL slow sql related optimization.

git gpg commit sign error:

SQL statement writing

The data in a table is about 400000 Like fuzzy query title The field is very slow. The title field has been indexed. MySQL someTitle% Such fuzzy query is fast on the premise of indexing.
So the following two SQL statements are very different
$sql1="... title like someTitle%" (0.001 seconds)

$sql2="... title like% someTitle%" (0.8 seconds)
