Deprecated: Function split() is deprecated. How to fix this statement?
提问by Chris45234325
I have the following statement which worked fine before PHP 5.3 using the split function:
我有以下语句在 PHP 5.3 之前使用 split 函数运行良好：
$command = split (" ", $tag[1]);
After upgrading to PHP 5.3, I get the Deprecated warning:
升级到 PHP 5.3 后，我收到已弃用警告：
Deprecated: Function split() is deprecated.

Use explode:
使用explode：
$command = explode(" ", $tag[1]);
This is the standard solution for this case.
这是这种情况的标准解决方案。
If you need to match on a regular expression (rather than something simple like a space), use preg_split. It's slower than explode, so there's no reason to use it unless you needa regex.
如果您需要匹配正则表达式（而不是像空格这样简单的东西），请使用preg_split. 它比 慢explode，因此除非您需要正则表达式，否则没有理由使用它。
BTW to do the opposite (join array elements into a string), use implode.
顺便说一句，做相反的事情（将数组元素连接成一个字符串），使用implode.

Well the first thing someone should do is checking the documenation: split
好吧，某人应该做的第一件事就是检查文档：拆分
It is recommended to use preg_splitor explode
建议使用preg_split或爆炸

提示
split() is deprecated as of PHP 5.3.0. preg_split()is the suggested alternative to this function. If you don't require the power of regular expressions, it is faster to use explode(), which doesn't incur the overhead of the regular expression engine.
自 PHP 5.3.0 起不推荐使用 split()。preg_split()是此函数的建议替代方案。如果您不需要正则表达式的强大功能，使用explode() 会更快，这不会产生正则表达式引擎的开销。
If you are going to split in " " you might consider explode to be a better alternative.
如果您打算拆分为“”，您可能会认为爆炸是更好的选择。
