Editor to share with you how to optimize the interface implementation efficiency of PHP, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

The reasons for inefficient execution can be found in many ways.

From the code level, the code quality is low, the execution efficiency will also have a great impact. From the hardware aspect, the server configuration is low, the server configuration is the foundation, this cannot run certainly slow. In terms of the amount of data, the query data is too much, the sql statement is too complicated, and the execution is slow.

Server

From the configuration to improve, for the overall implementation efficiency of the system is quite obvious, there is no doubt about this, as long as there is strength, naturally can be done in this area to improve.

Data query:

The optimization of this query involves sql optimization, or database optimization. Here are a few simple optimization solutions.

Sql optimization, the appropriate use of linked list queries, the use of joins (JOIN) to replace subqueries, generally large tables and multiple tables to avoid using JOIN, in this case the use of JOIN can not achieve the effect of simplifying the query. Sql optimization, query table data with precise field names to avoid unnecessary field queries. Sql optimization, the appropriate use of primary foreign keys and indexes. Sql optimization, appropriate use of in query, appropriate use of fuzzy query. Database optimization, the field uses a reasonable field type, another way to improve efficiency is to set the field to NOTNULL as far as possible to avoid space waste. Optimize the database and design the table structure reasonably.

Code optimization:

Code optimization also varies from person to person, everyone may have different coding habits and styles, and have their own opinions on improving code performance. Here are some of my views.

Foreach is used reasonably, and the cycle is applied in the loop as little as possible. In the case of too many cycles, it consumes performance very much.

In the loop, try to avoid data operations, especially query operations. In the case of too many cycles, the efficiency of multiple calls is very low, and the data can be obtained at once and then stitched together.

Similarly, in a loop, avoid multiple fetches of the configuration and calls to the time () function, and this declaration can be reused at one time.

In php, there is a difference between single quotation marks and double quotation marks. As a customary string, I use single quotation marks because it does not need to be compiled, and there may be no difference in efficiency, maybe just a little bit.

Make rational use of the functions in php, such as array functions are very rich, to make full use of, generally do not do their own support of the function method

You can use the concept of a dictionary to store the array in the form of a new index, which I often use in data reorganization.

According to the scenario, rational use of cache can reduce repeated data queries and improve efficiency.

A reasonable split function, such as a list query with details to view, can be split into two APIs to obtain data when needed and reduce resource waste.
