"PHP Public Platform Development Series"

01. Configure the interface
02. Public Platform Sample Code analysis
03. Subscription event (SUBSCRIBE) processing
04. Simple Reply Function development

First, Introduction

PHP public platform can be based on the information sent by users to judge, and then give the corresponding reply, with good interactivity. The following will simulate the simple reply function, according to this case, the developer can also basic understanding of the principle of interaction, for deeper development.

Second, the Thinking analysis

The user sends over the text information, we can extract the keyword, through the simple if...elseif...else ... Realize.

The key code is as follows:

if ($keyword = = "Hello") {$contentStr = "Hello";} ElseIf ($keyword = = "Suzhou") {$contentStr = "There is heaven, there is Suzhou and Hangzhou";} else{$CONTENTSTR = "Thank you for your attention" Zhuo Jin Suzhou "No.: Zhuojinsz";}

If the user sends "Hello", then reply "Hello", if the user sends "Suzhou", then reply "There is heaven, there is Suzhou and Hangzhou", other information, then reply to your welcome word.

Three, the complete code
