Question

我正在迭代一个数组;我的代码在第1行完整地打印数组，然后在下面的循环中打印每个单独的元素。如何生成数组应该无关紧要，并且在我将其打印出来的位置和逐个元素打印的位置之间没有代码。

第1行的输出是正确的;在循环生成的逐个元素的打印输出中，最后2个元素包含相同的数据，倒数第二个元素的数据被重复用于最后一个元素。

我的原始代码是在循环中进行一些额外的处理（而不是提供输出）。该代码正在做什么是无关紧要的，因为该代码被注释掉并且在我尝试调试此问题时已经被下面的简单代码所取代。

为什么输出会在循环中被修改？

以下是相关代码：

echo '<pre>'.print_r($flat, true).'</pre>';
foreach ($flat AS $tu_pid => $details) {
    echo '<pre>'.$tu_pid.': '.print_r($details, true).'</pre>';
}
die();

为清楚起见，这是最后一个元素，如第1行所示：

[TARG-E] => stdClass Object
(
    [stats] => stdClass Object
        (
            [id] => 1033
            [discount] => 0.00000
            [charged] => 49.90
            [charged_bd] => 49.90
            [fm_disc] => 0.00000
            [coupon_pct] => 0.00000
            [member_pct] => 0.00000
            [tu_sale] => 0.00000
            [tu_shelf] => 0.00000
            [tu_price] => 49.90
            [cart] => 49.9
            [list] => 49.9
            [regular] => 49.9
            [sale] => 
            [sale_pct] => 0.00000
            [sale_start] => 
            [sale_end] => 
            [list_all] => 0.00
            [reg_all] => 0.00
            [reg_tu] => 0.00
            [reg_child] => 0.00
            [price_tu] => 0.00
            [tu_child] => 0.00
            [nesting] => 0
            [cu_type] => 0
            [use_price] => 1
            [root] => 1
            [royalty_item] => -1
        )

    [lineage] => Array
        (
            [0] => Array
                (
                )

        )

    [owned] => 
    [products] => 
)

...并且由循环中的echo线表示：

TARG-E: stdClass Object
(
    [stats] => stdClass Object
        (
            [id] => 9745
            [discount] => 42.55975
            [charged] => 15.37
            [charged_bd] => 15.37
            [fm_disc] => 0.00000
            [coupon_pct] => 0.00000
            [member_pct] => 0.00000
            [tu_sale] => 32.95303
            [tu_shelf] => 0.00000
            [tu_price] => 15.37
            [cart] => 26.75174103
            [list] => 39.9
            [regular] => 39.9
            [sale] => 
            [sale_pct] => 0.00000
            [sale_start] => 
            [sale_end] => 
            [list_all] => 0.00
            [reg_all] => 0.00
            [reg_tu] => 0.00
            [reg_child] => 0.00
            [price_tu] => 0.00
            [tu_child] => 0.00
            [nesting] => 0
            [cu_type] => 0
            [use_price] => 1
            [root] => 
            [royalty_item] => 1019706
        )

    [lineage] => Array
        (
            [0] => Array
                (
                    [0] => PhotoGuide Set-6
                )

        )

    [owned] => 
    [products] => 
)

以下是相关代码的整个输出：

为什么这个PHP代码会提供此输出？
