[英]PHP Shell_Exec not working with variable
I'm trying to pass a variable into shell_exec, I've looked at other tutorials but they still dont help. 我正在尝试将变量传递给shell_exec,我看过其他教程,但它们仍然无济于事。
I want to pass $var[1] into the shell_exec so it will just display this specific file or directory's information 我想将$ var [1]传递到shell_exec中,这样它将只显示此特定文件或目录的信息
$output = shell_exec('ls -l'.$var[1]);
You should add some whitespace: 您应该添加一些空格:
$output = shell_exec('ls -l '.$var[1]);
