    $big = 999999999; // need an unlikely integer
    echo paginate<em>links( array(
    'base' =&gt; str</em>replace( $big, '%#%', esc<em>url( get</em>pagenum<em>link( $big ) ) ),
    'format' =&gt; '?paged=%#%', <br>

$paged = (get&#95;query&#95;var('paged')) ? get&#95;query&#95;var('paged') : 1;  

query&#95;posts(array(  
    'post&#95;type'      => 'post', // You can add a custom post type if you like  
    'paged'          => $paged,  
    'posts&#95;per&#95;page' => 3  
));
