Hello, a little help if someone is available, I want to make a small script about the categories so:  how is it correct?

 <?php if(category(1) ) { ?>
        aaaaaaa
<?php else if(category(2) ) { ?>
       bbbbbbb
<?php else if(category(2) ) { ?>
       ccccccccc
      <?php } ?>

how is it correct? Any idea?

@Romeo

This should give you category ID on search page
<?php
  $category = osc_search_category_id();
  $category_id = $category[0];
?>

Where should I put the category id ?

Before your code and change if conditions to category_id == 1 ...

I do not understand, how to change them?

<?php
  $category = osc_search_category_id();
  $category_id = $category[0];
?>

<?php if($category_id == 1) { ?>
        aaaaaaa
<?php else if($category_id == 2 ) { ?>
       bbbbbbb
<?php else if($category_id == 3) { ?>
       ccccccccc
<?php } ?>

Please read at least PHP basics before coding something
