3、PHP is a structured programming language, which means that it provides a way to solve computational problems by breaking them into discrete steps that can be carried out in a “top to bottom” fashion, one step at a time.

4、All structured languages share certain essential features.1.Manage input and output.To be useful, any language must provide an input/output (I/O) interface with a user. When a computer program is executed or a script is

5、interpreted, the user may be asked 5.Make decisions based on comparing values.Computers can’t make decisions by “thinking” about multiple possibilities in a human-like way. However, they can compare values and act on the

6、 results of those comparisons. Typically, a program will compare values and then execute instructions based on the results of those comparisons. In particular, such decisions are often embedded in branching structures th

7、at execute one set of instructions to the exclusion of others, based on a comparison of values.6.Perform repetitive calculations.Loop structures allow computers to perform repetitive calculations. These calculations may
