php-数组foreach修改

我有一个数组$test这样的：

Array ( 
    [CUST_TYPE] => 
        Array ( 
            [0] => Family 
            [1] => Regular 
            [2] => Corporate 
            [3] => Premium ) 
    [TOTAL_BALANCE] => 
        Array ( 
            [0] => 420946131.01 
            [1] => 41272033223.93 
            [2] => 38873647942.4 
            [3] => 10465337565.61 ) 
        )

我需要将此数组转换(打印)成这样的东西：

{
cust_type : Family,
balance : 420946131.01
},
{
cust_type : Regular ,
balance : 41272033223.93
},
and so on..

这是我使用的简单的foreach,但是它只能打印cust_type或balance

$cols = array_keys($testing);

foreach ($testing[$cols[1]] as $i => $j) {
        echo '{cust_type : ' . $j . 
             ', balance : ' . $<What should I print??> . '},';        
    }

请帮助.
谢谢.

解决方法:

使用array_map(PHP 4> = 4.0.6,PHP 5)

$json = json_encode(array_map(function($a,$b){ return array("cust_type"=>$a,"balance"=>$b);},$array["CUST_TYPE"],$array["TOTAL_BALANCE"]));

测试

[akshay@localhost tmp]$cat test.PHP 
<?PHP

$array = array( 
            "CUST_TYPE" => array( 
                                'Family', 
                                'Regular', 
                                'Corporate', 
                                'Premium' 
                               ), 
            "TOTAL_BALANCE" => array( 
                                420946131.01, 
                                41272033223.93,
                                38873647942.4 ,
                                10465337565.61 
                              )
             );


// PHP 4,5
$json = json_encode(array_map(function($a,$b){ return array("cust_type"=>$a,"balance"=>$b);},$array["CUST_TYPE"],$array["TOTAL_BALANCE"]),JSON_PRETTY_PRINT);

// Input
print_r($array);

// Output
print $json."\n";

?>

输出量

[akshay@localhost tmp]$PHP test.PHP 
Array
(
    [CUST_TYPE] => Array
        (
            [0] => Family
            [1] => Regular
            [2] => Corporate
            [3] => Premium
        )

    [TOTAL_BALANCE] => Array
        (
            [0] => 420946131.01
            [1] => 41272033223.93
            [2] => 38873647942.4
            [3] => 10465337565.61
        )
