循環遍歷結果並聚合並吐出php

Question

我試圖用下面的代碼完成：它執行SELECT，它應該返回（2）結果，這些結果每個拉~10項（總項目： 〜20）並將其顯示在頁面上。

實際發生的：它拉動第二結果，從而輸出只〜10個結果出來可能20左右，在$result VAR確實應該有一個總的循環後〜20項......但只有它有10 ..我測試了實際輸出和查詢...

有什麼想法？

Answer 1

foreach($result as $r){ 
    $xmlUrl = $r['FW_ArtSrcLink']; 
    $ConvertToXml = simplexml_load_file($xmlUrl); 
    # -> Setup XML 
    $newsStory = $ConvertToXml->channel->item; 
} 

你做破壞性分配$newsStory這裏，我認爲它是一個數組所以使用$newsStory[] = ...代替。
