php 升级到 5.3+ 后出现的一些错误,如 ereg(); ereg_replace(); 函数报错,eregereg_replace

在php5.3环境下运行,常常会出现

 Deprecated: Function ereg() is deprecated in...和Deprecated: Function ereg_replace() is deprecated in...这些类型的报错提示。
  其原因在于:php5.3以上的版本不支持ereg()函数,而是使用preg_match()函数;不支持ereg_replace()函数,而使用preg_replace()函数。
  解决方法:将不支持的函数修改为支持的函数即可。
   
      例如
  if(eregi('^('value', $value)
  改为:
  if(preg_match('/value/', $value)
   
  再例如:
  $string = ereg_replace(' value', ' ', trim($string)); 
  改为:
  $string = preg_replace('{ value}', ' ', trim($string)); 
   
解决Deprecated: Assigning the return value of new by reference is deprecated in报错

因为我们现在php是5.3的原因,在php5.3之中可以直接用”=”,而之前因为在本地上测试都是5.3以下的php环境用的是”=&”符号。

在 5.3版本之后已经不允许在程序中使用”=&”符号。如果你的网站出现了Deprecated: Assigning the return value of new by reference is deprecated in 错误,别着急,先定位到出错的文件,查找下是不是在程序中使用了”=&”,发现使用了”=&”符号,去掉‘&’符号之后程序运行 正常。

问题:Deprecated: Function set_magic_quotes_runtime() is deprecated in 
导致这个提示的原因是在PHP5.3后此特性(set_magic_quotes_runtime())已经关闭。
而且在PHP6中已经完全移除此特性。
你可以注释或者删除掉出错的行,或者是在set_magic_quotes_runtime()前面加@符号
