我正在尝试从mysql中获取数组并使用其值打印每个列。
这是我到目前为止所做的:
获取所有列:
$query = "SHOW COLUMNS FROM user_settings";
$resultx = mysql_query($query);$temp=0;$p = array();
while ($row = mysql_fetch_array($resultx)) {
$p[$temp] = $row["Field"];$temp++;
}
Foreach列名称获取数据,其中用户ID = $ SESSION [' id']
foreach ($p as $f) {
$json = array();
$newquery = "SELECT * FROM user_settings WHERE uid = '" . $_SESSION['id'] ."'";
$newresult = mysql_query($newquery);
while($newrow = mysql_fetch_array($newresult)) {
$json[$f] = $newrow[$f];
}
print json_encode($json);
}
这很好用。问题是打印的阵列是这样的:
{"column1":"data"}{"column2":"data"}{"column3":"data"}
相反我希望json编码打印:
[{"column1":"data","column2":"data","column3":"data"}}

您可以删除所有这些,因为它是多余的。
$query = "SHOW COLUMNS FROM user_settings";
$resultx = mysql_query($query);$temp=0;$p = array();
while ($row = mysql_fetch_array($resultx)) {
$p[$temp] = $row["Field"];$temp++;
}
同样删除foreach循环,这样我们只剩下查询和while循环查询。
$json = array();
$newquery = "SELECT * FROM user_settings WHERE uid = '" . $_SESSION['id'] ."'";
$newresult = mysql_query($newquery);
print json_encode(mysql_fetch_assoc($newresult));
这应该使json_encode()函数编码多维结果数组。
还尝试删除mysql_ *函数并使用mysqli_ *函数或PDO,因为mysql_ *函数已被折旧。

试试这个:
$newquery = "SELECT * FROM user_settings WHERE uid = '" . $_SESSION['id'] ."'";
$newresult = mysql_query($newquery);
print json_encode(mysql_fetch_array($newresult));
我认为你不需要休息。
