2. Do not declare variables inside the loop, especially variables such as objects

3. In multiple nested loops, if possible, the longest loop should be placed on the inner layer and the shortest loop on the outer layer, so as to reduce the number of cpu cross-loop layers and optimize program performance.

4. Use single quotation marks instead of double quotation marks to optimize PHP performance.

5. Replace i=i+1 with iTunes 1. It accords with the habit of cAccord plus, and it is still efficient.

6. Optimize Select SQL statements and do as few Insert and Update operations as possible to achieve the purpose of PHP performance optimization.

7. Use PHP internal functions as much as possible

8. Do as few file operations as possible, although the file operation efficiency of PHP is not low.

9. Do not use regular expressions when you can manipulate functions with PHP internal strings

10. When file_get_contents can be used instead of file, fopen, feof, fgets and other methods, use file_get_contents as far as possible, because it is much more efficient.
