system - PHP shell_exec using UNC paths -

-

in php, can not execute command via shell_exec, system, or exec, when using unc paths. here example:

what works:

$command = shell_exec("dir c:\\"); echo $command;

here not work. echo's nothing.

$command = shell_exec("dir \\\\server\\dir"); echo $command;

when run dir \\server\dir in windows command window or powershell executes fine.

unc paths work, user php service running must have access share.

i assume running php iis. if case, default user iusr_machinename. sure user has access share.

if you're running apache, check task manager on server determine user running apache service. give user name access share.
