php5.3开始出现的Function ereg() is deprecated Error问题解决办法

简介:

PHP 5.3 ereg() 无法正常使用,提示“Function ereg() is deprecated Error”。问题根源是php中有两种正则表示方法,一个是posix,一个是perl,php6打算废除posix的正则表示方法所以后来就加了个preg_match。此问题解决办法很简单,在ereg前加个过滤提示信息符号即可:把ereg()变成@ereg()。这样屏蔽了提示信息,但根本问题还是没有解决,php在5.2版本以前ereg都使用正常,在5.3以后,就要用preg_match来代替ereg。所以就需要变成这样,原来:

ereg ( " ^[0-9]*$ " , $page )

变成:

preg_match ( " /^[0-9]*$/ " , $page )

特别提醒:posix与perl的很明显的表达区别就是是否加斜杠,所以与ereg相比,后者在正则的前后分别增加了两个”/”符号,不能缺少。
Tips:此问题在php5.2之前版本不会出现。

宝塔PHP8.1安装fileinfo拓展失败解决办法
在宝塔面板安装PHP8.1后,fileinfo扩展安装失败,手动尝试也报错。通过分析错误信息,在Makefile中修改CFLAGS添加`-std=c99`,并执行`make clean`清除缓存后,重新编译安装成功。最后在php.ini中启用fileinfo扩展并重启PHP服务。注意需调整CFLAGS为`-std=c99 -g`,去掉`-O2`。
