Use of static variables in PHP for instance analysis and php instance analysis

This article describes how to use static variables in PHP. We will share this with you for your reference. The details are as follows:

1. Define static variables

Public static $ endpoint, $ accessKeyId, $ accessKeySecret, $ bucket;

2. static variable assignment

Protected function _ initialize () {self: $ endpoint = C ('oss _ endpoint'); self: $ accessKeyId = C ('oss _ ACCESS_ID '); self :: $ accessKeySecret = C ('oss _ ACCESS_KEY '); self: $ bucket = C ('oss _ TEST_BUCKET ');}

3. Use static variables

Public static function getOssClient () {try {$ ossClient = new OssClient (self ::$ accessKeyId, self :$ accessKeySecret, self ::$ endpoint, false );} catch (OssException $ e) {printf (_ FUNCTION __. "creating OssClient instance: FAILED \ n"); printf ($ e-> getMessage (). "\ n"); return null;} return $ ossClient ;}
