What we bring today is the function of querying daily horoscope. This function is very simple. Enter a constellation name and an identifier (for example, "") on the platform ), the background program matches this identifier to call the corresponding function. The specific process is as follows: 1. Use the string splitting function explode (w3school) to obtain the constellation name. 2. Match the constellation name

What we bring today is query dailyConstellationThis function is very simple.PlatformInput onConstellationName and an identifier (for example, "+"). The background program matches this identifier to call the corresponding function.

Specific process: 1. Use the string splitting function explode (w3school) to obtainConstellationName.

2. SetConstellationThe name matches with the correspondingConstellationId.

3. Pass this number to the corresponding API.

4. Receive xml format data returned by the API.

5. process data in xml format.

6. Generate the result.

As a beginner, I made some effort in step 5. The xml format returned by the API is

     
          
   Overall Operation

   Love fortune

   Working Condition        
   
    
2
           
       
  ......
  

  
 

First, I use the file_get_contents () function to return the data returned by the API. FileRead a string. Then use

            
  ……           
  
   ……
              
    
     ……
     
    
   
  
 

In this way, the "object"-> item-> title method can only read the data of the first item.

 foreach ($xml->item as $th) {            $content_title[$i] = $th->title;            $content_rank[$i] = $th->rank;            $content_value[$i] = $th->value;            $i++;        }

Traverse this object "$ xml" and store each group of data in an array using an auto-incrementing variable I.

The foreach statement is used to traverse arrays cyclically.

For each loop, the value of the current array element is assigned to the value variable (the array pointer is moved one by one), and so on.

Syntax

foreach (array as value){    code to be executed;}

Example

The following example demonstrates a loop that outputs the value of a given array:

 ";}?>
