如何在PHP中将文本块拆分为2个字符串？

Question

我有一个文本块，包含以下内容：

[/+]There is my first text[+/]. There is my second text.

[/+]There is my third text.[+/]
There is my fourth text.

...

现在，我想将其拆分为2个字符串：

1. $str_1 = "There is my first text.";

2. $str_2 = " There is my second text.

[/+]There is my third text.[+/]

There is my fourth text.

...";

你能告诉我：“如何在PHP中将文本块拆分为2个字符串？”。

Answer 1

你可以在php中使用爆炸功能

explode($delimiter, "String");

Answer 2

我不确定你的问题，但我认为你可能正在寻找这个

$str = "[/+]There is my first text[+/]. There is my second text.

[/+]There is my third text.[+/]
There is my fourth text.";

preg_match_all('/(\[\/\+])?([\w\s.]+)(\[\+\/])?/',$str,$m);

$str = "";
foreach($m[2] as $k => $v){
  ${"str".$k} = $v;
}

echo $str0."\n";
echo $str1."\n";
echo $str2."\n";
echo $str3."\n";
