[转]php5.3(放弃的函数替换)deprecated 错误问题汇总

php 5.3 从一方面来讲,可以说在07年计划PHP6的中的一个pre版本,增加了很多功能,统一了很多语法,使PHP变得更加强大与简洁。

可是我们在升级使用5.3以后会发现以前的旧项目会出现一些问题,统计架构规划,PHP当然会对一些别名,重复功能function进行归类整理,并把一些不用的正式在php 5.3以后删除掉.故不建议在新项目继续使用.

PHP 5.3 有两个deprecated

E_DEPRECATED and E_USER_DEPRECATED

下面是旧的项目中会在php 5.3以后碰到的问题
define_syslog_variables
register_globals
register_long_arrays
safe_mode
magic_quotes_gpc
magic_quotes_runtime
magic_quotes_sybase
在PHP.ini 注释用#已经不再建议使用.
Deprecated functions:

call_user_method() 可以用 call_user_func() 替代
call_user_method_array() 可以用 call_user_func_array() 替代define_syslog_variables()
dl() 反对在使用DL加载扩展,php5.3 以后应用php.ini配制
ereg() 可以用 preg_match() 替代
ereg_replace() 可以用 preg_replace() 替代
eregi() 用 preg_match() i 参数替代
eregi_replace() 用 preg_replace() i 参数替代
set_magic_quotes_runtime() 用 magic_quotes_runtime() 替代
session_register() session_unregister() session_is_registered()
以上三个统一用 $_SESSION 替代
set_socket_blocking() 用 stream_set_blocking() 替代
split() 用 preg_split() 替代
spliti() 用 preg_split() 模式 ‘i’ 替代
sql_regcase()
mysql_db_query() 用 mysql_select_db() mysql_query() 替代mysql_escape_string() 用 use mysql_real_escape_string() 替代
关于时区处理,统一用Timezone对像
Deprecated features:

直接返加new 实例不再建议使用. PHP 6 将不再支持
