Use a returned array inline?

[mkoga]

Does anyone know of a way to use a returned array inline?

 

For example:

//$this->getList() returns an array
$item1 = $this->getList()[0];

 

Don't know if this or something like it is possible, but it'd be pretty cool.

//$this->getList() returns an array

$item1 = $this->getList();

 

now $item1 will contain the array

 

you can use $item1[0];

yeah that would work. i was wondering if anyone had a trick to do it inline. i should probably explain what i'm doing.

 

consider:

$fileinfo = $this->input->files('file');

 

$fileinfo would then contain the info for an uploaded file named 'file'. however, it'd be nice if it were possible to do something like this:

$filename = $this->input->files('file')['name'];

 

i suppose i could convert $GLOBAL to an object, but that's just more work. if it's not possible, that's cool, just thought i'd ask.

if you only want to return the first item from the array returned by $this->input->files('file') use array_shift, eg:

$filename = array_shift($this->input->files('file'));

 

array_shift will remove the first item from the array and return its value.

thanks, i knew about that one. the trick would be to return any key you wanted by index.

Say $this->input->files('file') returned an array like so:

array (path, filename, filesize) you could use list to get the filename

list(,$filename,) = $this->input->files('file');

 

or create your own function which will return what ever item you want from the array.
