Question

我是phpMyAdmin的新手，请有人帮忙。我在php中有一个多维数组，我试图将信息插入到我的数据库中，但由于某种原因，信息会重复出现。例如，如果我在我的阵列上只有三个人的信息，数据库将插入5个人重复一些。程序执行的查询多于应有的查询。我不知道这是否与phpMyAdmin或我的PHP代码有关。

require("connect_db.php");
foreach($alumni as $alum){


//firstName and lastName must exist since they are required fields.
$first_name= $alum['firstName'];
$last_name= $alum['lastName'];

//check if the alum has provided a summary.
if (array_key_exists('summary', $alum)){
    $summary= $alum['summary'];
}else{
    $summary= "No summary available";
}

//check if the alum has provided a headline.
if (array_key_exists('headline', $alum)){
    $headline= $alum['headline'];
}else{
    $headline= "No headline available";
}

//check if the alum has provided a picture.
if (array_key_exists('pictureUrl', $alum)){
    $picture= $alum['pictureUrl'];
}else{
    $picture= "No picture available";
}

mysql_query("INSERT INTO profile    VALUE('','$first_name','$last_name','$headline','$summary', '$picture')");
//echo $first_name." ". $last_name." ".$headline." ".$summary;
}
mysql_close($link);

表格如下所示：

ID  firstname  lastname  headline  summary  pictureURL
----------------------------------------------------
1    Jane       Smith     Student   blah      blah
-----------------------------------------------------
2    Jane       Smith     Student   blah      blah
-------------------------------------------------------
3    John       Doe       Student   blah      blah
--------------------------------------------------------
4    Jake       Jacobs    Student   blah      blah
-----------------------------------------------------
5    John       Doe       Student   blah      blah
------------------------------------------------------
