如何在php中编写多行输出

Question

我想在php文件中写入命令的输出。但是当我打开文件时，只输出一行。

  $myfile = fopen("status1.txt", "a+"); 
  $cmd="asterisk -rx 'sip show peers'|greo OK";
  $test1=system($cmd);
  fwrite($myfile, $test1);
  fclose($myfile);

输出

1004  /1004     (Unspecified)                            D                 0         OK                                  
1005  /1005     (Unspecified)                            D   N             0         OK                                  
1006  /1006     (Unspecified)                            D   N             0         OK                                  
2501  /2501     (Unspecified)                            D                 0         OK                                  
2502  /2502     (Unspecified)                            D   a             0         OK                                  
2503  /2503     (Unspecified)                            D   a             0         OK                                  
2504  /2504     (Unspecified)                            D                 0         OK  

但是在文件中只有第一行写

您可以尝试使用exec函数而不是system

。

exec($cmd,scanme);
$scanme = implode("n",$scanme);

exec (string $command [， array &$output [， int &$return_var]])

你的情况:

  $myfile = fopen("status1.txt", "a+"); 
  $cmd="asterisk -rx 'sip show peers'|greo OK";
  exec($cmd,$test1);
  $test1 = implode("n",$test1);
  fwrite($myfile, $test1);
  fclose($myfile);
