php - Change order of array -


i have code in wordpress gets images attached specific post.
puts information of post in array pulls images using built in wordpress function wp_get_attachment_image

i use foreach loop display images in image slider. problem have is putting 'image1' in position 1 of array, , 'image2' in position 0 of array.
it's displaying image 2 first.

here's code.

    $args = array(       'post_type' => 'attachment',       'numberposts' => -1,       'post_status' => null,       'post_parent' => $post->id      );      $attachments = get_posts( $args );               $images = array($attachments);     echo '<div id="postslider"><div class="slides_container">';     if ( $attachments ) {         foreach ( $attachments $attachment ) {         echo '<div>' . wp_get_attachment_image($attachment->id, 'large') . '</div>';         }          echo '</div>';         if(sizeof($attachments) > 1) {             echo '<div class="slidercontrols">             <a href="#" class="sliderbtnprev">previous</a>             <a href="#" class="sliderbtnnext">next</a>             <span class="sliderpagination">1 of 3</span>             </div>';         }     }        echo '</div>';

from i've read foreach loop preserve order of array. so, i'm thinking need change order of array loop sees 'image1' (array position [1]) first.

my knowledge of arrays limited , i'm not sure how this.. appreciated.

if want change order programmatically, have @ various array sorting functions in php, especially

  • uasort()— sort array user-defined comparison function , maintain index association
  • uksort()— sort array keys using user-defined comparison function
  • usort()— sort array values using user-defined comparison function

but wordpress checkout http://codex.wordpress.org/template_tags/get_posts
