PbootCMS附件上传时报错：
上传失败：UNKNOW: Code: 8192; Desc: stripos(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior; File: /www/wwwroot/aaa.xxxx.com/core/function/file.php; Line: 176;
解决办法：打开/core/function/file.php，搜索以下
<code style="padding-right:0.3em !important;text-align:right !important;height:auto !important;width:2.7em !important;line-height:20px !important;font-size:14px !important;display:block !important;">1if(stripos($types, $ext) !== false) |
替换成
1if(stripos($types, chr($ext)) !== false) |
|
