处理数组中的数组?

我的代码中还有以下foreach循环:

foreach ($_POST as $key => $value){ 
    $message .= $key . " = " .$value ."\n\n<br />"; 
}

哪一个是最后一个。

或者问题可能在于:

curl_setopt($ch, CURLOPT_POSTFIELDS, $req);

不喜欢生成的字符串中的%5B0%5D,即

transaction%5B0%5D=USD+21.00

使用代码$req = http_build_query($_POST);

原始问题:

我收到以下错误消息:

[Sun Aug 04 10:00:00 2012] [error] [client 000.0.00.000] PHP Warning:  stripslashes() expects parameter 1 to be string, array given in /var/www/page.php on line 20
[Sun Aug 04 10:00:00 2012] [error] [client 000.0.00.000] PHP Stack trace:
[Sun Aug 04 10:00:00 20122] [error] [client 000.0.00.000] PHP   1. {main}() /var/www/page.php:0
[Sun Aug 04 10:00:00 2012] [error] [client 000.0.00.000] PHP   2. stripslashes() /var/www/page.php:20

问题代码是:

Line 19: foreach ($_POST as $key => $value) {
Line 20:     $value = urlencode(stripslashes($value));
Line 21:     $req .= "&$key=$value";
Line 22: }

$_POST包含以下内容:

Array
(
    [transaction] => Array
        (
            [0] => USD 21.00
        )

    [payment_request_date] => Sat Aug 04 10:00:00 PDT 2012
    [return_url] => http://000.000.000.000/success.php
    [fees_payer] => EACHRECEIVER
    [ipn_notification_url] => http://000.000.000.000/ipn.php
    [sender_email] => buyer_0394820394_per@gmail.com
    [verify_sign] => slkdfj30r2489urj0947830ru0ty80ur0er037jfgoiru932e.as329e
    [test_ipn] => 1
    [cancel_url] => http://000.000.000.000/cancel.php
    [pay_key] => AP-SLKJ30F9J90J3RSD3
    [action_type] => PAY
    [transaction_type] => Adaptive Payment PAY
    [tracking_id] => E4902RJF2
    [status] => COMPLETED
    [log_default_shipping_address_in_transaction] => false
    [charset] => windows-1252
    [notify_version] => UNVERSIONED
    [reverse_all_parallel_payments_on_error] => false
)

由于数组中的数组,stripslashes()是否给我一个问题?如果是,我如何处理$_POST循环中的foreeach,如果不是,可能会出现什么问题?

只需使用函数http_build_query,它将为您生成一个URL编码的查询字符串。

$query_str = http_build_query($_POST);

答案 1 :(得分:0)

function stripslashes_every_string($array){
  foreach($array as $key => $value){
    $array[$key] = is_array($value) ? stripslashes_every_string($value) : stripslashes($value);
  }
  return $array;
}
$postdata = stripslashes_every_string($_POST);
