mysqli_fetch_assoc錯誤

Question

$link = mysqli_connect('localhost', 'root', '', 'mutli_page_form'); 

$result = mysqli_query($link, "SELECT * FROM wills_children WHERE id=77"); 
$row = mysqli_fetch_assoc($result); 

$data = unserialize($row['children']); 

錯誤

Warning: mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given in 

似乎是什麼問題？

它試圖拉取的序列化數據;

a:1:{i:0;a:3:{i:0;s:15:\"Natural Chlid 1\";i:1;s:15:\"Natural Chlid 2\";i:2;s:15:\"Natural Chlid 3\";}} 

Answer 1

試試這個：

if ($result = mysqli_query($link, $query)) { 

    /* fetch associative array */ 
    if($row = mysqli_fetch_assoc($result)) { 
     $data = unserialize($row['children']); 
    } 

    /* free result set */ 
    mysqli_free_result($result); 
}
