Batch include files while keeping the namespace clean

Question

I've been using the following snippet to include multiple files:

foreach(glob(APP_PATH."libs/*.php") as $path)
{
 include $path;
}

The thing is, I don't want to have the $path variable available inside the included files.

Fictitious solution:

include unset($path);

This would have worked if unset returned the value of the unsetted variable. It doesn't though. It returns void.

Answer 1

as your using foreach, after every loop the variable is reset and reused.

for example:

foreach(glob(APP_PATH."libs/*.php") as $path)
{
    include $path;
    //$path is now set to the next variable.
}

so you only need to unset $path once at the end of the foreach loop.

for example:

foreach(glob(APP_PATH."libs/*.php") as $path)
{
    include $path;
}
unset($path);

Jobs done now, $path is totally free and clear from the memory.

have you tried the following.

function HideString(&$_)
{
    $t = $_;
    unset($_);
    return $t;
}

foreach(glob(APP_PATH."libs/*.php") as $path)
{
    include HideString(&$path);
}

To prevent that the $path is available inside the included files try to use eval("include $path;"). Im not sure what happens to vars inside eval()...

Put it into a function/method, then it is only available inside the function (namespace).
