Hello all!

I have a question regarding arrays and the way I can use a value.

Let's say I have this string:

$s = 'banana,apple,mellon,grape,nut,orange'

I want to explode it, and get the third value. For this I would normally do:

$a = explode(',', $s);
echo $s[2];

That's all fine, but is there a way to get the value directly, without
having to write another line in my script. I mean something like this:

echo explode(',', $s)[2];


echo {explode(',', $s)}[2];

I couldn't find out this answer anywhere, that's why I posted here.

Cheers and thanks!

Sure it CAN be done.  Nobody laugh too loud here... But...


$s = 'banana,apple,mellon,grape,nut,orange';
echo preg_replace('/([^,]+,){3}([^,]+).*/', '$2', $s);

Outputs: grape

The {3} part is equivalent to the array position. Change that number, and you change which word will get displayed.
