PHP split alternative?
提问by igorgue
PHP is telling me that split is deprecated, what's the alternative method I should use?
PHP 告诉我 split 已被弃用，我应该使用什么替代方法？
回答by Sarfraz
explodeis an alternative. However, if you meant to split through a regular expression, the alternative is preg_splitinstead.
explode是一个替代方案。但是，如果您打算通过正则表达式进行拆分，则替代方案是preg_split。
回答by salathe
splitis deprecated since it is part of the family of functions which make use of POSIX regular expressions; that entire family is deprecated in favour of the PCRE (preg_*) functions.
split已弃用，因为它是使用 POSIX 正则表达式的函数系列的一部分；整个系列都被弃用，以支持 PCRE ( preg_*) 函数。
If you do not need the regular expression functionality, then explodeis a very good choice (and would have been recommended over spliteven if that were not deprecated), if on the other hand you do need to use regular expressions then the PCRE alternate is simply preg_split.
如果您不需要正则表达式功能，那么这explode是一个非常好的选择（split即使没有被弃用，也会被推荐），另一方面，如果您确实需要使用正则表达式，那么 PCRE 替代方案就是preg_split.

preg_splitif you need to split by regular expressions.str_splitif you need to split by characters.explodeif you need to split by something simple.
preg_split如果您需要通过正则表达式拆分。str_split如果您需要按字符拆分。explode如果你需要用简单的东西来分割。
Also for the future, if you ever want to know what PHP wants you to use if something is deprecated you can always check out the functionin the manual and it will tell you alternatives.
同样是为了将来，如果您想知道 PHP 在不推荐使用的情况下希望您使用什么，您可以随时查看手册中的功能，它会告诉您替代方案。

You can use the easier function preg_match instead, It's better and faster than all of the other ones.
您可以改用更简单的函数 preg_match，它比所有其他函数都更好更快。
$var = "<tag>Get this var</tag>";
preg_match("/<tag>(.*)<\/tag>/", $var , $new_var);
echo $new_var['1'];
Output: Get this var
输出： Get this var

Had the same issue, but my code must work on both PHP 5 & PHP 7..
有同样的问题，但我的代码必须同时适用于 PHP 5 和 PHP 7 ..
Here is my piece of code, which solved this.. Input a date in dmY format with one of delimiters "/ . -"
这是我的一段代码，它解决了这个问题..输入一个带有分隔符“/.-”的 dmY 格式的日期
<?php
function DateToEN($date){
if ($date!=""){
list($d, $m, $y) = function_exists("split") ? split("[/.-]", $date) : preg_split("/[\/\.\-]+/", $date);
return $y."-".$m."-".$d;
}else{
return false;
}
}
?>
