本帖最后由 菜鸟小飞 于 2016-12-22 21:47 编辑

wamp建个本地网站，上传源码后显示Parse error: syntax error, unexpected 'mt_srand' (T_STRING) in E:\wamp\www\conn.php on line 2
Call Stack#TimeMemoryFunctionLocation10.0010150640{main}( )..\index.php:0
php如下：希望大神帮忙修改一下

自己顶一下，希望大神能够看到！！

mt_srand((double) microtime() * 1000000)   前面多了个半角符号


书写规范点，自己更新也方便   else 前面尖括号都不写，，，，，，，，
