PHP Syntax design arrays Why not use the universal {} curly braces? Other programming languages are included in the array's initial values in curly braces {}.

PHP can only be used array= (), in the new version of the phrase used in the square brackets []. Is the curly brace {} not more in line with the general public?
C # int[] array = {1, 2, 3, 4, 5, 6};
Java int[] arr = {0,0,0,0,0,0,0,0,0,0,0,};
Python () tuple [] List/Array {} The dictionary is not mixed into a,,, Python is a little relative to PHP. []
Golang arr:=[...] int{1,1,1,1,1,1,1,1,1}

Are all curly braces {} contain,,,

PHP uses [] in parentheses, is it the original because {} curly braces have some special uses in PHP $a = "aaaaaa{$b}aaaaaa"; Afraid to create ambiguity? , or it is easier to knock [] the brackets than the bridge {} curly braces, without the SHIFT key.
The Blind guess!!! Just don't know how to deal with the inside of the PHP development Group for what reason, use [] square brackets, without {} curly braces.

Curly braces are big! Big! Parentheses,,, PHP, this data structure is mixed, curly braces, the largest brackets,, haha,, anything can be enclosed, curly braces {} This symbol graphics feel also meet the visual requirements.

It's strange to use curly braces, in the mathematical context, {} stands for the collection, [] represents the list, the collection is not sequential, and the list is ordered. So more and more modern languages use [] to represent the list.

Supplementary @yetone Answer:

PHP之前很多年数组的表示形式一直是 array()，而 [ ] 方式是在PHP5.4中才引入的。如果你写过一段时间PHP，你就会发现用 [ ] 表示数组也是你内心真正想的一件事，这是顺其自然的。

And there's an array () It's too much to write, okay?

PHP的数组根本就不是传统的C数组，而是 map、链表、堆、栈......

You can use the short array definition syntax since 5.4 to replace array () with [].
Programming languages typically use [] to represent arrays or queues, and {} to represent dictionaries or collections.
In fact, in PHP, arrays can represent dictionaries because they are key-value pairs. So the main idea was to use {}.

The latest version of php5.4+ has been supported, but with few people. Most of them are PHP 5.2,php5.3.3

[] In the PHP5.4 has started to support, and not so the language definition array are used {}, such as JS

An array of PHP is actually a dictionary, so you can't use an array of other languages to compare it to a dictionary.

The Dictionary of PY is {}
The object of JS is {}
Swift's Dictionary is [:]

It seems that the newly emerging language tends to use brackets
And php5.4 is newer, so use the brackets
