[英]Store Session Array in Database
我有陣列會議....
$_SESSION['Names'] = array (11,15,26);
$_SESSION['Location'] = array (35,42,10);
我想將它們存儲在我的數據庫中......
$que = "Insert into tblpeople (DateTimePosted, first, second, third) VALUES(now(),'$_SESSION['Names'][0], $_SESSION['Location'][0])','$_SESSION['Names'][1], $_SESSION['Location'][1])','$_SESSION['Names'][2], $_SESSION['Location'][2])')";
$exec = mysql_query($que);
保存后,我的數據庫(tblpeople)顯示以下值:
DateTimePosted: 2014-01-03 16:23:02
first: Array [0],Array [0]
第二: 數組[1],數組[1]
第三: 數組[2],數組[2]
相反,我希望我的輸出是......
DateTimePosted: 2014-01-03 16:23:02
第一名: 11,35
第二名: 15,42
第三名: 26,10
怎么了?
要在字符串中展開多維數組,需要將它們用大括號括起來:
$que = "Insert into tblpeople (DateTimePosted, first, second, third)
VALUES(now(),
'{$_SESSION['Names'][0]}, {$_SESSION['Location'][0]}',
'{$_SESSION['Names'][1]}, {$_SESSION['Location'][1]}',
'{$_SESSION['Names'][2]}, {$_SESSION['Location'][2]}')";
您還在值中添加了一些括號。
但是,這似乎是將數據存儲到數據庫中的一種非常奇怪的方式。 為什么每列中有兩個以逗號分隔的值,而不是將每個值拆分為單獨的列? 為什么要將數組元素存儲到不同的列中,而不是將每個值與單獨的表一起使用?
使用此功能
$x=serialize($_SESSION['Names']);
它返回一個字符串,你可以保存在任何地方
而這個功能扭轉了它
$_SESSION['Names']=unserialize($x);
嘗試這個
<?php
session_start();
$_SESSION['Names'] = array (11,15,26);
$_SESSION['Location'] = array (35,42,10);
$refNumbers = $_SESSION['Names'];
$partIds = $_SESSION['Location'];
$combined = array();
foreach($refNumbers as $index => $refNumber) {
if(!array_key_exists($index, $partIds)) {
throw OutOfBoundsException();
}
$combined[] = array(
'Names' => $refNumber,
'Location' => $partIds[$index]
);
}
print_r($combined);
$combine1 = implode(",",$combined[0]);
$combine2 = implode(",",$combined[1]);
$combine3 = implode(",",$combined[2]);
$que = "insert into tblpeople (DateTimePosted, first, second, third) VALUES(now(),'$combine1','$combine2','$combine3')";
//$exec = mysql_query($que);
?>
