通过Regex将字符串解析为具有新行链的数组，而不使用PHP中的任何删除
问题描述：
I need to parse this string:
$str = "
ABC
DEF
GHI
JKL" ;
into this array:
$arr = [
"
",
"ABC
",
"
",
"DEF
",
"GHI
",
"
",
"JKL"
] ;
I tried many combinations, but no luck:
$arr = preg_match_all("/[^
]+[
]+/",$str,$out) ;
What Regex can handle that?
我需要解析这个字符串： p>
$ str = “
ABC
DEF
GHI
JKL”;
code> pre>
进入此数组： p>
$ arr = [
“
”，
“ABC
”，
“
”，
“DEF
”，
“GHI
“，
”
“，
”JKL“
];
code> pre>
我尝试了很多组合，但没有运气： p>
$ arr = preg_match_all（“/ [^
] + [
] + /”，$ str，$ out）;
code> pre>
Regex可以处理什么？ p>

答
This pattern does the job:
preg_match_all('~
+|.+
?~', $str, $matches);
As an aside, preg_match_all returns the number of matches or false, the matches are stored in the third parameter.
