目前版本 php版本：php-5.3.5-Win32-VC9-x86
运行早期写的PHP代码，提示ereg() is deprecated，查看PHP.INI文件
; overload(replace) single byte functions by mbstring functions.; mail(), ereg(), etc are overloaded by mb_send_mail(), mb_ereg(),; etc. Possible values are 0,1,2,4 or combination of them.; For example, 7 for overload everything.; 0: No overload; 1: Overload mail() function; 2: Overload str*() functions; 4: Overload ereg*() functions; http://php.net/mbstring.func-overload; mbstring.func_overload = 0
解决办法
mbstring.func_overload = 4 ;Overload ereg*() functions或
mbstring.func_overload = 7 ;Overload ereg*() str*() mail() functions
