需要有关split array的帮助
数组示例:
array (
[0] =>
:some normal text
:some long text here, and so on... sometimes
i'm breaking down and...
:some normal text
:some normal text
)
好的,现在使用
preg_split( '#\n(?!s)#' , $text );
我得到了
[0] => Array
(
[0] => some normal text
[1] => some long text here, and so on... sometimes
[2] => some normal text
[3] => some normal text
)
我想得到这个:
[0] => Array
(
[0] => some normal text
[1] => some long text here, and so on... sometimes i'm breaking down and...
[2] => some normal text
[3] => some normal text
)
正则表达式可以获得整行,也可以在换行时拆分!

“换行符”定义不明确。 Windows仅使用CR + LF(\ r \ n),Linux LF(\ n),OSX CR(\ r \ n)。
在preg_ *常规异常中有一个鲜为人知的特殊字符\ R,它们匹配所有三个:
preg_match('/^\R$/', "\r\n"); // 1

这是一个有效的例子,即使你在字符串中嵌入冒号字符(但不是在行的开头):
$input = ":some normal text
:some long text here, and so on... sometimes
i'm breaking: down and...
:some normal text
:some normal text";
$array = preg_split('/$\R?^:/m', $input);
print_r($array);
结果:
Array
(
[0] => some normal text
[1] => some long text here, and so on... sometimes
i'm breaking: down and...
[2] => some normal text
[3] => some normal text
)

file()
将文件读入数组。
答案 3 :(得分:0)
如果将数组拆分为:character ..
print_r(preg_split('/:/', $input));
答案 4 :(得分:-2)
$lines = explode("\n", $text);
