PHP Micro-trust public Platform Development (iv) Recovery function development _php Example

First, Introduction

The micro-credit public platform can be judged according to the information sent by the user, and then the corresponding reply is given, which has good interactivity. The following will simulate the simple reply function, according to this case, the developer can also basically understand the principle of micro-letter interaction, deeper development.

Second, the analysis of ideas

The user sends over the text message, 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, under the Hangzhou and Suzhou";
} else{
$contentStr = "Thank you for your attention" Zhuo Jin Suzhou "micro-signal: Zhuojinsz";
}

If the user sends "Hello", then reply "Hello", if the user sends "Suzhou", then reply "There is paradise, the next has Suzhou and Hangzhou", other information, then reply your welcome word.
