Question

import java.net.*;
import java.io.*;
import java.util.regex.Pattern;

public class AppDev {
public static void main(String[] args) throws Exception {

URL website = new URL("MyWebsite.php");
BufferedReader in = new BufferedReader(
new InputStreamReader(website.openStream()));

    String inputLine;
    StringBuilder sb = new StringBuilder();
    while ((inputLine = in.readLine()) != null) {
        System.out.println(inputLine);
        sb.append(inputLine);
    }
    in.close();
  }
}

我有这个代码从php文件读取并显示此输出：

Event Number: 1
Date: 2018-05-16
Time: 12:00:00
Event: meeting with friend
Event Number: 5
Date: 2018-05-03
Time: 01:34:37
Event: what the hell
Event Number: 6
Date: 2018-05-03
Time: 01:35:05
Event: Rage at MySQL
Event Number: 16
Date: 2018-06-20
Time: 08:00:00
Event: hfdhfdfgfg

我想将每个事件及其信息在数组中自行拆分，然后在jtextfield中输出每个数组，例如第一个条目将是

Event Number: 1
Date: 2018-05-03
Time: 01:34:37
Event: meeting with friend

等等

这个技巧可以帮到你

<强>输入

$string = 'Event Number: 1Date: 2018-05-16Time: 12:00:00Event: meeting with friendEvent Number: 5Date: 2018-05-03Time: 01:34:37Event: what the hellEvent Number: 6Date: 2018-05-03Time: 01:35:05Event: Rage at MySQLEvent Number: 16Date: 2018-06-20Time: 08:00:00Event: hfdhfdfgfg';

<强>解决方案

在事件编号之前添加字符串中未出现的特殊元素或单词，并按ltrim删除第一次出现的元素或单词。 str_replace会将Event Number替换为|Event Number。

我在这里使用|。

代码如下：

$string = ltrim(str_replace('Event Number','|Event Number',$string),'|');
$array = explode('|',$string);//convert the string into array.
echo "<pre>";print_r($array);

<强>输出

Array
(
    [0] => Event Number: 1Date: 2018-05-16Time: 12:00:00Event: meeting with friend
    [1] => Event Number: 5Date: 2018-05-03Time: 01:34:37Event: what the hell
    [2] => Event Number: 6Date: 2018-05-03Time: 01:35:05Event: Rage at MySQL
    [3] => Event Number: 16Date: 2018-06-20Time: 08:00:00Event: hfdhfdfgfg
)

我从java中的php文件中读取代码，我希望按事件分割代码行
