Shorthand for arrays: is there a literal syntax like {} or []?
PhpArraysSyntaxPhp Problem Overview
What is the shorthand for array notation in PHP?
I tried to use (doesn't work):
$list = {};
It will be perfect, if you give links on some information about other shorthands for PHP.

Solution 1 - Php
Update:
As of PHP 5.4.0 a shortened syntax for declaring arrays has been introduced:
$list = [];
Previous Answer:
There isn't. Only $list = array();
But you can just start adding elements.
<?php
$list[] = 1;
$list['myKey'] = 2;
$list[42] = 3;
It's perfectly OK as far as PHP is concerned. You won't even get a E_NOTICE for undefined variables.

As for shorthand methods, there are lots scattered all over. If you want to find them just read The Manual.
Some examples, just for your amusement:
$arr[]
shorthand forarray_push
.- The
foreach
construct echo $string1, $string2, $string3;
- Array concatenation with
+
- The existence of
elseif
- Variable embedding in strings,
$name = 'Jack'; echo "Hello $name";
Solution 2 - Php
YES, it exists!!
Extracted from another Stack Overflow question:
> The shortened syntax for arrays has been rediscussed, accepted, and > is now on the way be released with PHP 5.4
Usage:
$list = [];

Solution 3 - Php
It is also possible to define content inside [ ] like so:
$array = ['vaue1', 'value2', 'key3'=>['value3', 'value4']];
This will only work in php5.4 and above.
Solution 4 - Php
There are none as of PHP 5.3.
Solution 5 - Php
Nope, it was proposed and rejected by the community, so for now only syntax for arrays is array().
Solution 6 - Php
You can declare your array as follows:
$myArray1 = array(num1, num2, num3);
$myArray2 = array('string1', 'string2', 'string3');
$myArray3 = array( 'stringkey1'=>'stringvalue1', 'stringkey2'=>'stringvalue2');
$myArray4 = array( 'stringkey1'=>numValue1, 'stringkey2'=>numValue2);
$myArray5 = array( numkey1=>'stringvalue1', numkey2=>'stringvalue2');
$myArray6 = array( numkey1=>numValue1, numkey2=>numValue2);
You can have as many embedded arrays as you need.
Solution 7 - Php
The only way to define an array in php is by the array()
language construct. PHP doesn't have a shorthand for array literals like some other languages do.
Solution 8 - Php
I just explode strings into an array like so:
$array = explode(",","0,1,2,3,4,5,6,7,8,9,10");
