PHP show if with different categories array or variable? -

having problems here, think overlooking simple...

i have cms have multiple categories.

how create variable or array has included categories groups want use in show if statement ??

so example:

<?php            $catsrow = array(     'cat_1' => '41','46','62',      'cat_2' => '41','45','63',     'cat_3' => '41','43','65'  );  ?>     <?php if       (catsrow[0] || catsrow[1] || catsrow[2]) == ($row_detailrs1['category'])   { echo 'do work' }       else {  ?> 

thanks in advance!!

i guess asking is, how compare array multiple groups inside. need compare different grouped categories..

like $catsarray = array(cat_1 => '2,3,4' , cat_2 => '5,6,7' , cat_3 => '8,9,10')

if $row['cat_from_page'] == $catsarray (any of groups) show { } 

????

you may need explode parts of array

kinda $parts = explode(',' , $cat);

but need implode whole thing 1 array

like implode (',', $parts);
