php exec返回的结果比直接进入命令行的结果少 [英] php exec returns less results than entering into command line directly

问题描述

我有一个执行命令，其行为与通过Penguinet给予linux的命令不同。

$ b

  $ res = exec （'cd / mnt / mydirectory /; zcat log_file.gz'）; 
 echo $ res 
  

将命令直接放入命令行时，日志文件中的条目。但是，当我访问具有 exec（）命令的PHP页面时，我只能看到1.它的格式正确。为什么PHP只显示一个结果？
$ b

编辑：

看起来这只是只返回最后一行。

解决方案

试试这个：

  exec（'cd / mnt / mydirectory /; zcat log_file.gz'，$ res）; 
 print_r（$ res）; 
  

I have an exec command that is behaving differently than the same command given to linux through Penguinet.

 $res = exec('cd /mnt/mydirectory/; zcat log_file.gz');
 echo $res

When putting the commands directly into the command line, I see about 100 entries in the log file. However when I access the PHP page that has the exec() command, I see only 1. And it is formatted correctly. Why does PHP show me only one result? How can I make it show the entire contents of the file?

EDIT:

Seems this is only returning only the last line. How can I change that?

解决方案

try this:

exec('cd /mnt/mydirectory/; zcat log_file.gz', $res);
print_r($res);
