如何打印其他數組內的數組內的內容？

-2

我試圖在Drupal 7安裝中打印值爲「Viviana」的值，這個值在配置文件節點內的某處。我想要的是打印輸出用戶名的字段內容。如何打印其他數組內的數組內的內容？

從來就試過這個選項，但從來就得到了錯誤：print $field_nombrecompleto1['und'][0]['value'];

The error was Notice: Undefined variable: field_nombrecompleto1 in /home/liga/public_html/sites/all/themes/liga/templates/user-profile.tpl.php on line 7

I'm使用print_r的發佈後的輸出（一點點縮短）（）。

感謝您的幫助！在你的輸出

錯誤已經足夠清楚了：變量'field_nombretopleto1'不存在。你確定你是print_r'ing正確的變量？ –

是的，這就是爲什麼我不明白... – Rosamunda

可能重複[遞歸php函數，將嵌套數組轉換爲嵌套的html塊]（http://stackoverflow.com/questions/1766995/recursive-php-function -that-turns-nested-array-into-nested-html-blocks） –

看，你應該嘗試：

print $your_var['variables']['elements']['profile_alumnos']['view']['profile2'][5]['field_nombrecompleto1']['#object']->field_nombrecompleto1['und'][0]['value'];

哪裏$your_var是您用於print_r變量。

謝謝！它打印出我想要的輸出！爲什麼我應該使用與print_r一樣的var？ – Rosamunda

它不是你應該的，它是我關於數據結構的唯一信息。你可以引用你感興趣的路徑中的任何變量，然後從那裏引用。這完全取決於您打算如何處理這些數據，以及您需要訪問哪些部分。 –

例如，您可以執行'$ field_nombrecompleto1 = $ your_var ['variables'] ['elements'] ['profile_alumnos'] ['view'] ['profile2'] [5] ['field_nombrecompleto1'] ['＃object '] - > field_nombretopleto1;'然後'print $ field_nombretople1 ['und'] [0] ['value'];'（你的原始代碼）應該可以工作。 –

如何打印其他數組內的數組內的內容？
