php apis

file_put_contents("/home/iknow/search.txt",var_export($searchResult,true));

iconv("gbk", "utf-8",$doc_info['title']);

xml中不能有&号 要用cdata包起来下

查看字符串编码

mb_detect_encoding

转码用这个

mb_convert_encoding

file_put_contents('utf-8.txt', $bafeite_utf8);

输出数组
$reqStr = var_export($req,true);
file_put_contents('request.txt', $reqStr);exit;

implode合并数组成字符串

--disable-fileinfo

vim

grep 'mb_' -r *  

set encoding=utf-8

cat AppMap.data | awk '{print $1}' | xargs | sed "s/\s\+/\',\'/g"

case

make: *** [ext/fileinfo/libmagic/apprentice.lo] Error 1

这是由于内存小于1G所导致.
在./configure加上选项:

--disable-fileinfo

mysql:

sudo yum install mysql-server

sudo service mysqld start

修改root密码：

mysqladmin -u root password NEWPASSWORD
