1. 在创建一个load.php文件的时候,上传照片出问题了,提示:Warning: : failed to open stream: Permission denied in /Users/Griselda/Sites/phpTest/upload_file.php

chmod 757 upload
Copy after login

2. 在使用cookie的时候,user那一个参数不能使用数字开头的值,否则cookie不会创建成功

3. 在使用php连接数据库的时候显示Warning: mysql_connect(): No such file or directory in ...

网上查了一下之后发现是因为apache/php是系统自带的,而mysql是自己安装的,所以mysql路径跟默认的不一致,我们要做的就是使默认路径下有需要的socket文件

Griselda@ZengのMacPro:/var$$sudo mkdir mysql
Password:
Griselda@ZengのMacPro:/var$$cd mysql/
Griselda@ZengのMacPro:/var/mysql$$ln -s /tmp/mysql.sock mysql.sock
ln: mysql.sock: Permission denied
Griselda@ZengのMacPro:/var/mysql$$sudo ln -s /tmp/mysql.sock mysql.sock
Griselda@ZengのMacPro:/var/mysql$$ls
mysql.sock
Copy after login

这样就好使了..
