php - Parse error: syntax error, unexpected '[' How to fix this one?

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

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

            

 $cipher->initialize(

            array(
 'driver'=>'openssl',
 'key' => $key

            )
 );
