Great to see a StackExchange for WP! Ok so I'm working on pulling images and dates from piklist custom post types and I got this working on my local, BUT when I move it to WPEngine I get a white page until I take the code out. The date code doesn't throw a blank page but won't pull the dates entered. Can anyone tell me what about this code may be causing this? Thanks in advance!

CODE

single.php

?php while ( have_posts() ) : the_post(); ?

  ?php

    $image_ids = get_post_meta(get_the_ID(), 'my_media', false);

    foreach ($image_ids as $image)
    {

      echo 'img src=" ' . wp_get_attachment_image_src($image, 'large')[0]  . ' "/';

    }
  ?

  ?php echo get_post_meta(get_the_ID(), 'my_date', true); ?

  ?php get_template_part( 'content', themeblvd_get_part( 'single' ) ); ?

  ?php themeblvd_single_footer(); ?

  ?php if ( themeblvd_supports( 'comments', 'posts' ) ) : ?
    ?php comments_template( '', true ); ?
  ?php endif; ?

?php endwhile; ?

The problem is this part:

wp_get_attachment_image_src($image, 'large')[0]

In old PHP versions like 5.3 and below, you cannot reference an entry ([0]) from the returned array of a function. The problem is that WP Engine is still on PHP 5.3, which reached end of life recently and doesn’t get security updates anymore. For the history see PHP 5.3 - Thanks for all the Fish.

You have two options:

Find all occurrences of modern syntax and rewrite them to make it compatible with 5.3. In this case:
```
$img_data = wp_get_attachment_image_src($image, 'large');
$src = $img_data[0];
```
Switch to a newer PHP version, preferably 5.5. If your current hoster cannot do that find a better one.
