Code not working on different php version

Question

i have problems with part of my code. In my local machine this code works, i have php7

$totals = array_values(
    array_count_values(
        array_map(function($x)
        {
            return explode('-', $x)[0];
        }, $arraySKU2)
    )
);

This is the error that i get on server that have php version 5.3.3.

Parse error: syntax error, unexpected '[' in

I tried to find solution on internet, but i didnt make it. Can someone help me please, i dont know how to write changes?

Would help to tell us what version is on the machine that's not working. — Jonnix, Jan 22 '19 at 14:51
all 4 functions which you are using having support till 4.0 to 7, — devpro, Jan 22 '19 at 14:54
Ouch. 5.3.3 went end of life nearly _5_ years ago. You can't really go on using 7 on your dev machine if you're having to deploy on this antiquated version. Can I suggest you find better hosting? — Jonnix, Jan 22 '19 at 14:54
remove this line and run your code on your server, check if it make sense to debug — devpro, Jan 22 '19 at 14:54
@devpro Not sure array access on function returns are though? — Jonnix, Jan 22 '19 at 14:54
@JonStirling that is not my decission, i must use that version on server... — , Jan 22 '19 at 14:55
one more idea, create a sub domain, and upgrade php version on sub domain and try. — devpro, Jan 22 '19 at 14:55
@dokica *which line* ---> code which you shared in your question. — devpro, Jan 22 '19 at 14:58

This is not working:

 return explode('-', $x)[0];

Try assiging the result of explode to a variable and access the first element from that variable.

According to the release notes for PHP 5.4, accessing data this way has not been possible in versions older than 5.4.0

Finally, your code could look like this:

$totals = array_values(array_count_values(array_map(function ($x) {
    $explodedValues = explode('-', $x);
    return $explodedValues[0];
}, $arraySKU2)));

I agree, though I don't think it would cause the error provided, though I guess that could be anywhere. – Jonnix Jan 22 '19 at 15:04
How i can do that? – Jan 22 '19 at 15:06
Yes error is in this part [0] – Jan 22 '19 at 15:06
@dokica I've added the proper code for that – Nico Haase Jan 22 '19 at 15:08

Questions that are about basic PHP syntax errors should not be answered. They should be closed as a duplicate of [PHP Parse/Syntax Errors; and How to solve them?](//stackoverflow.com/questions/18050071) only. If you want to point out their mistake, just post a comment. See: [Should one advise on off topic questions?](//meta.stackoverflow.com/q/276572/1768232).
