php - Eliminate double posts in "other posts from this category" on single post page -

i using following code display posts same category on current post page:

<?php  global $post; $categories = get_the_category(); $ceker=false;  foreach ($categories $category[0]) { if ($ceker == false){     $ceker=true;         ?>     <h3 class="naslovostalih">other posts category:</h3>     <ul class="clanciostalih">      <?php      $args = array(         'numberposts' => 10,         'category' => $category[0] -> term_id,          'exclude' => $post->id     ); }      $posts = get_posts($args);          foreach($posts $pz) { ?>             <li>                 <?php                 $title = $pz->post_title;                 $link = get_permalink($pz->id);                 printf('<a class="linkpost" title="%s" href="%s">%s</a>', $title, $link, $title);                 echo get_the_post_thumbnail($pz->id, 'thumb-232');                 echo '<div id="excerptcu">';                  $pz = $pz->post_excerpt; if (strlen($pz) > 160) { $pz = substr($pz,0,strpos($pz,' ',160)); } ; $pz = $pz . ' ...'; echo apply_filters('the_excerpt',$pz);                 echo '</div>';                 ?>                <p class="more-link-wrapper2"><?php printf('<a class="read-more     button" title="%s" href="%s">opširnije</a>', $title, $link, $title);?></p>             </li>          <?php } // end foreach ?>  <?php } // end if ?>  </ul> 

it works perfect, problem other posts doubled have kind of output:

post1 (which in cat blizzard , in category europe)

content of post1

other posts category: (should take posts first category , blizzard)

post2
post3
post4
post2
post3
post4

so "other posts" doubled , cant figure out why.

any ideas?

foreach problem. first one. managed solve issue adding break command after closing foreach.
