Foreach loop with multiple arrays

Question

This is what I want:

---

foreach($_POST[\'something\'] as $something){
    foreach($_POST[\'example\'] as $example){
        $query = mysq

I think the best way would be as a single loop to build a query. This should work even if your arrays are not the same length:

$size1 = count($_POST['something']);
$size2 = count($_POST['example']);
if( $size1 >= $size2 ) {
     $size = $size1;
} else {
     $size = $size2;
}

$sql = "INSERT INTO table (row, row2) VALUES";
$values = array();
for( $i=0; $i<$size; $i++ ) {
    $values[] = "('" . mysql_real_escape_string($_POST['something'][$i]) . "','" . mysql_real_escape_string($_POST['example'][$i]) . "')";
}

$sql .= implode(",", $values);

mysql_query($sql);

Also more secure because it escapes your input. This would also be even easier using placeholders with PDO.
