PHP：将多行命令行输出输出为不同的行

问题描述：

PHP: Output multiple line command-line outputs as different lines. Sorry if the title is difficult to understand. Basically I want my output like A, instead of B. It currently looks like B. I have tried nl2br. The script I am trying to run is:

Script:

echo "Virus Scan Results:";
$scanme = system('cd /var/www/upload/files; clamscan --remove=yes '.$furl);
printf(nl2br($scanme));

802931t_e_s_t.txt: OK

PHP：将多行命令行输出输出为不同的行。如果是标题很难理解。基本上我希望我的输出像A，而不是B.它目前看起来像B.我试过nl2br。我试图运行的脚本是： p>

脚本： p>

 
echo“病毒扫描结果：”; 
 $ scanme = system（'  cd / var / www / upload / files; clamscan --remove = yes'。$ furl）; 
printf（nl2br（$ scanme））; 
  pre> 
 
  A： p  >

答

why are you using nl2br if this is on the command line?

nl2br outputs <br /> tags for new lines... which would have no meaning on command line

Edit

Two things:

1 try

system('cd /var/www/upload/files; clamscan --remove=yes '.$furl, $scanme);

2 You may want to use the exec function instead of system

e.g.

exec('cd /var/www/upload/files; clamscan --remove=yes '.$furl, $scanme);
$scanme = implode("
",$scanme);

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

答

If you are running on the commandline, a newline is represented as ' ', or ' ' in a Windows environment. So make sure there is a at the end of each line, and you should get the output you want. Edit:
Tom: Oops. Fixed.

答

Have you tried just printing the output of the command directly?

echo "Virus Scan Results:";
echo exec('cd /var/www/upload/files; clamscan --remove=yes '.$furl);

PS. You really should sanitise the input like so (if you are not doing so already):

$furl = escapeshellarg($furl)

escapeshellarg() - Escape a string to be used as a shell argument
