1, if the method of the class can be defined as static, as far as possible to define as static, it will increase the speed of nearly 4 times times.2. The speed of $row [' ID '] is 7 times times that of $row[id].3. Echo is faster than print, and uses

Use single quotes instead of double quotes to include strings, which is faster. Because PHP will search for variables in strings enclosed by double quotes, but not in single quotes. Note: Only echo can do this, it is a "function" that can treat

In PHP development, to become a programmer, you must learn to make PHP programs run faster. Use single quotes instead of double quotes to include strings, which is faster. Because PHP will search for variables in strings enclosed by double quotes,

1. If a method is static, make a static declaration of it. The rate can be increased to 4 times times. 2.echo is faster than print. 3. Use Echo's multiple parameters (meaning: a comma instead of a period) instead of a string connection. 4.
