php 封装的mysql错误

[weixin_42154352]

求助谢谢！

print_r($r); 贴出结果

[下雨的声音丶]

报错很明显了啊，没得fetch_all()这个方法 具体有哪些 可以参考 http://php.net/manual/zh/class.mysqli-result.php 官方文档

[xuzuning]

print_r($r); 应为 print_r(get_class_methods($r));

print_r($r);
应为
print_r(get_class_methods($r));

我知道落后了，关键我没找到合适的ISS PHP5.6以上的

PHP 我升级5.6.27了，还是不行

[xuzuning]

你可以用循环读取来模拟 fetch_all 方法

[山东蓝鸟贵薪]

先检测一下SQL语句是否有问题，
最好是使用兼容性稳定的 MYSQL+PHP　相关的版本

[JoeBlackzqq]

跟你装的php-mysql插件的版本有关吧，跟php版本无关！
