Question

在mysql命令的mysql查询结果中

language id   language name 
1               English
2               Hindi
3               Russian


$language_name =$conn->prepare("SELECT language_id, language_name FROM language_master");
                $language_name->setFetchMode(PDO::FETCH_BOTH);
                $language_name->execute();
                $language_name = $language_name->fetch();

如何在php中打印/回显所有语言和ID？就像在桌子上一样。

感谢您的帮助。

Answer 1

您可以使用

var_dump($language_name);

或

print_r($language_name);

打印整个数组。

修改

所以你可以用作foreach-loop：

foreach($language_name as $key => $value) { echo $key . ' => ' . $value; echo "</br>"; }

Answer 2

while($row = $language_name->fetch()) {
    $allRows[] = $row;
}

然后在php

foreach($allRows as $value){
echo $value['language_id'];
}

Answer 3

如果我能帮到你，你想在表中显示结果..使用循环来获取数据。 e.g

 <?php 
if(!empty($language_name)):  
$i = 0;
foreach($language_name as $rows): 
$i++;

echo $rows['language_id']; //for the language id
echo $rows['language_name ']; //for language name
endforeach; 
 endif; 
?>
