php codeIgniter: syntax error, Unexpected '['

Question

The php codeIgniter application, which runs in windows, when ported to the server gives the following error:

Parse error: syntax error, Unexpected '[' in /home/givix/Domains/givix.com.br/public_html/givix/application/Libraries/Amazon3integration_lib.php on line 79

PHP Error was encountered

Severity: Parsing Error

Message: syntax error, Unexpected '['

Filename: Libraries/Amazon3integration_lib.php

Line Number: 79

Backtrace: (...)

Not locally. So I guess it’s not logical, I thought it was some server configuration.

I made some modifications to the file .htaccess, but I don’t know anyone ever had a similar problem.

Lembando that the local machine is windows and the server is linux. (cent)

Local configuration:

• win 10
• easyphp 16
• Apache 2.4.18 x86
• PHP 5.6.19 x86
• Mysql 5.7.11 x86

Web setup:

• I’ll check on

The page that is set the error is this:

The stretch that he arrow the error is this:

 $sharedConfig = [
        'region'  => $this->region,
        'version' => $this->version,
        'scheme' => $this->scheme,
        'credentials' => [
            'key'    => AWS_ACCESS_KEY,
            'secret' => AWS_SECRET_KEY,
        ],
    ];

Answer 1

Replace the code you say is wrong with this one:

$sharedConfig = array(
    'region'  => $this->region,
    'version' => $this->version,
    'scheme' => $this->scheme,
    'credentials' => array(
        'key'    => AWS_ACCESS_KEY,
        'secret' => AWS_SECRET_KEY,
    ),
);

Possibly the server must be in a PHP version earlier than 5.4 and why it does not accept the above syntax.

See explanation in the link: http://php.net/manual/en/language.types.array.php

Highlight of the link says: From PHP 5.4 you can also use the contracted array syntax, which you exchange array() for [].

I recommend asking the server (or host) infrastructure to upgrade PHP, otherwise you might encounter other similar errors when trying to use third-party libraries with more current code. (as this is the case from what I see)

Good luck!
