Question

我有一个包含字符串的变量。例如：

15/11/12 14:56:49 INFO jvm.JvmMetrics: Initializing JVM Metrics with processName=JobTracker, sessionId=
15/11/12 14:56:49 INFO mapreduce.JobSubmitter: Cleaning up the staging area file:/tmp/hadoop-pranay/mapred/staging/pranay1505087555/.staging/job_local1505087555_0001
15/11/12 14:56:49 ERROR tool.ImportTool: Encountered IOException running import job: java.io.FileNotFoundException: File does not exist: hdfs://127.0.0.1:54310/home/<some id>/sqoop-1.4.5.bin__hadoop-2.0.4-alpha/lib/avro-1.7.5.jar
    at org.apache.hadoop.hdfs.DistributedFileSystem$18.doCall(DistributedFileSystem.java:1122)
    at org.apache.hadoop.hdfs.DistributedFileSystem$18.doCall(DistributedFileSystem.java:1114)
    at org.apache.hadoop.fs.FileSystemLinkResolver.resolve(FileSystemLinkResolver.java:81)

为了得到这种结果，我该怎么做？

    $message    =   
    'Dear User1,

    Your record submitted has been disapproved by User.

    Remarks: 

    Document No.: 
    Record Title: Test1
    Record URL: http://myapp.dev/records?id=1

    Sincerely,

    Admin

    Dear User1,

    Your record submitted has been disapproved by User.

    Remarks: 

    Document No.: 
    Record Title: Test2
    Record URL: http://myapp.dev/records?id=2

    Sincerely,

    Admin';

我想我可以使用Dear User1, Your record submitted has been disapproved by User. Remarks: Document No.: Record Title: Test1 Record URL: http://myapp.dev/records?id=1 Record Title: Test2 Record URL: http://myapp.dev/records?id=2 Sincerely, Admin？

来操纵字符串

请提及我错过或您想知道的事情。任何想法都会非常感激！

Answer 1

使用nl2br()获得所需的输出。

echo nl2br($message);

输出

Dear User1,

Your record submitted has been disapproved by User.

Remarks: 

Document No.: 
Record Title: Test1
Record URL: http://myapp.dev/records?id=1

Sincerely,

Admin

Dear User1,

Your record submitted has been disapproved by User.

Remarks: 

Document No.: 
Record Title: Test2
Record URL: http://myapp.dev/records?id=2

Sincerely,

Admin

请参阅demo

Answer 2

迟到总比没有好。试试这个功能

function manipulate($text){
    $texts = preg_split("/(Remarks:|Sincerely,|Document No.:)/",$text,-1, PREG_SPLIT_DELIM_CAPTURE);
    $str = $texts[0];
    $str .= "Remarks: \n\nDocument No.:";
    for($x=0;$x<count($texts);$x++){
        if($texts[$x]=='Document No.:'){
            $str .= trim($texts[($x+1)],"\r\n");
        }   
    }
    $str.= "\n\nSincerely,\n\nAdmin";
    return $str;
}

如果你使用这个作为html使用nl2br()喜欢

nl2br(manipulate($message)); //where $message is your "Dear User1,...."

Answer 3

我认为你需要在html页面中显示。尝试过nl2br（）？

我认为使用heredoc语法应该更好，例如：

$message = <<< EOT_MSG
    'Dear User1,
     ...
     ....
EOT_MSG;

Answer 4

我认为你可以使用类似this的东西，替代heredoc。
