Question

myarray[] = $my[$addintomtarray]  
//52 elements  
for ($k=0; $k <= 12; $k++){  
    echo  $myarray[$k].' ';  
}  
echo '<br>';   
for ($k=13; $k < 26; $k++){  
    echo  $myarray[$k].' ';  
}  
echo '<br>';   
for ($k=26; $k < 39; $k++){  
    echo  $myarray[$k].' ';  
}  
echo '<br>';  
for ($k=39; $k <= 51; $k++){  
    echo  $myarray[$k].' ';  
}   

how to shorten this array code…all I am doing here is splitting an array of 52 elements into 4 chunck of 13 elements each. In addition I am adding formation with br and space

thanks

Use the modulus operator (%) to know when you are at a multiple of 13:

for ($k=0; $k <= 51; $k++){  
    echo  $myarray[$k].' ';
    if (($k > 0) && (($k % 13) === 0)) {
        echo '<br>';
    }
}
