Question

I need to build an update query from an associative array from a POST

The POST contains multiple Associative arrays and a couple of key/value pairs

I can sort out which arrays to use but am stuck at building the update query string

array1 (
i => 1 // This is used for each WHERE clause and is the row id
a => 2
b => 3
c => 4
)

array2 (
i => 2
a => 2
b => 3
c => 4
)

I NEED:
“UPDATE table SET a=’2′, b=’3′, c=’4′ WHERE id=’array[i]'”

I have tried all kinds of foreach, while, implode methods pieced together from other posts but none of them deal with this specific problem. Any help would be appreciated. THanks

Try the following:

$id = array_shift($array);
$fields = array();

foreach($array as $field => $val) {
   $fields[] = "$field = '$val'";
}

$query = "UPDATE table SET " . join(', ', $fields) . " WHERE id = '$id'";
