php 升级到 5.3+ 后出现的一些错误,如 ereg(); ereg_replace(); 函数报错_PHP
在php5.3环境下运行,常常会出现
代码如下:
if(eregi('^('value', $value)
改为:
代码如下:
if(preg_match('/value/', $value)
再例如:
代码如下:
$string = ereg_replace(' value', ' ', trim($string));
改为:
代码如下:
$string = preg_replace('{ value}', ' ', trim($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
