PHP error for const array

Question

hello in my PHP file i got error on host for this line that defines const array:

const telegram_methods=['sendMessage'=>'sendMessage','answerCallbackQuery'=>'answerCallbackQuery','forwardMessage'=>'forwardMessage'];

after some changes in host configurations. the error is:

Parse error: syntax error, unexpected '[' in /........./st_datas.php on line 8

what is the problem of this line or host configurations? and this post: PHP Parse/Syntax Errors; and How to solve them? is so general and not duplicate of my question.

Constants can't be arrays, but it could be a static field instead (if in class). — Nigel Ren, May 28 '17 at 07:03
make it static as constant only be use for single value reference — Exprator, May 28 '17 at 07:05
Ok. thanks Nigel Ren & Exprator. but i used this way with no problem before — Solivan, May 28 '17 at 07:08

Maybe for your php version. If your php version >= 5.4, you can use brackets to define array.

So try it:

const telegram_methods = array('sendMessage'=>'sendMessage','answerCallbackQuery'=>'answerCallbackQuery','forwardMessage'=>'forwardMessage');

Unfortunately It's need php>=5.6 to define array as constant in class! – Mohammad Hamedani May 28 '17 at 07:10
Thanks @Mohammad Hamedani. my host admin changes php version from 5.6 to 5.3 without notice to me and it was prblem – Solivan May 28 '17 at 07:43

In regards to your follow up question (arrays are not allowed in class constants) it means simply as it says.

This has been updated in PHP 7 but before then if you need to set a class variable as an array simply drop the constant.
