Parse error: syntax error, unexpected '[' How to fix this one? [duplicate]

Question

I'm trying to initialize a function of CI in my native code.

$cipher->initialize(
        [
         'driver'=>'openssl',
         'key' => $key
        ]
     );

I'm getting an error of Parse error: syntax error, unexpected '['

Can I ask how to fix this?

Using Php 5.3.3

Answer 1

You are using PHP 5.3. The Array Initialization Construct: [] will not work. Instead, use this approach:

    <?php

        $cipher->initialize(
                array(
                 'driver'=>'openssl',
                 'key' => $key
                )
        );

Answer 2

Your PHP version doesn't support [] use array() instead.

Answer 3

Don't use [], Use:

 <?php

        $cipher->initialize(
                array(
                 'driver'=>'openssl',
                 'key' => $key
                )
        );
