php - Foreach 用于数组内的数组

Question

我有一个数组，我对它做了一个 print_r，它返回了这个......

Array ( [0] => Array ( [invoiceid] => 2 [client] => Test 1 [invoicedeliverymethod] => email [paymenttimeallotment] => 15 [clientid] => 1 [date] => 2012-04-12 [enddate] => 2012-04-02 00:00:00 [total] => 250.86 [remainingbalance] => 250.86 [ispaid] => No [isagentpaid] => No [datedistributed] => Not distributed [invoicedcontact] => 1 ) [1] => Array ( [invoiceid] => 1 [client] => Test 1 [invoicedeliverymethod] => email [paymenttimeallotment] => 15 [clientid] => 1 [date] => 2012-04-12 [enddate] => 2012-03-31 23:59:59 [total] => 602.29 [remainingbalance] => 602.29 [ispaid] => No [isagentpaid] => No [datedistributed] => 2012-04-12 [invoicedcontact] => 1 ) )

我试图运行这段代码......

 foreach($resultArray as $row => $value){
    echo $value . "<br/>";
}

并返回 Array Array。

如何获取这些数组中的值？

Answer 1

您需要迭代内部数组中的元素，如下所示：

foreach($resultArray as $row => $innerArray){
  foreach($innerArray as $innerRow => $value){
    echo $value . "<br/>";
  }
}

Answer 2

foreach($resultArray as $row => $value){
    foreach($value as $row2 => $value2)
        echo $value2 . "<br/>";
}
