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];
or
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...
<?php
$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.
