problema afisare cate numere prime are vectorul

[wikedx]

Salut am o problema cu afisarea numerelor prime din vectorul

<?php
error_reporting(E_ALL ^ E_NOTICE);
$ok=0;
$k=0;
$d=2;
$i=1;
$vectorS = array(31,33,434,2);
for( $i; $i <= 4; $i++ )
{
     $ok=1;
	for( $d; $d <= $vectorS[i]/2; $d++ )
     {
         if($vectorS[i]%$d==0)
         $ok=0;
         if($ok==1)
         $k++;
     }
}
    if($k>0)
    print $k;
    else
    print 'Nu exista';
?>

Imi afiseaza "Nu exista" in loc de "2"

Initializeaza-l pe $d cu 2 in for:

for( $d = 2; $d <= $vectorS[i]/2; $d++ )
{
         if($vectorS[i]%$d==0)
         $ok=0;
         if($ok==1)
         $k++;
     }

d l-am initializat la inceput cu 2 si varianta lui siur nu merge

$vectorS[$i], nu $vectorS

$ok=0;
$k=0;
$d=2;
$i=1;
$vectorS = array(31,33,434,2);
for($i = 0; $i < 4; $i++ )
{
     $ok=1;
    for( $d = 2; $d <= $vectorS[$i]/2; $d++ )
         if($vectorS[$i]%$d==0) 
                $ok=0;
     if($ok==1)
         $k++;
}
    if($k>0)
