PHP Difference between array() and []
arrays, php, square-bracket, syntax
Solution
Following `[]` is supported in PHP >= 5.4:
['name' => 'test', 'id' => 'theID']
This is a short syntax only and in PHP < 5.4 it won't work.
Problem
I'm writing a PHP app and I want to make sure it will work with no errors. The original code: ``` <?php $data = array('name' => 'test', 'id' => 'theID'); echo form_input($data); ?> ``` Would the following work with no errors or is not recommended for some reason? ``` <?= form_input(['name' => 'test', 'id' => 'theID']); ?> ``` Are there any difference? I've looked again the data about `array()` and the short array method with square brackets `[]` in PHP.net but I'm not sure. And also, is the short php tag `<?= ?>` fine for echoing? Is there any version issue? (provided is enabled in php.ini)
