从嵌套数组中选择数据

Question

我遇到了问题，我有这样的数据

$query = mysql_query("SELECT * FROM ticket");
while ($r = mysql_fetch_assoc($query)){
$data_workgroup=$r['workgroup'];
$explode= explode(",",$data_workgroup);
print_r($explode);

我得到了这个

Array ( [0] => Technical Support)
Array ( [0] => Marketing [1] => Network Engineer )
Array ( [0] => Technical Support )
Array ( [0] => Technical Support [1] => Network Engineer )

我需要从该数组中获取值，因此我只能显示Workgroup Value

的数据

SELECT * FROM ticket where workgroup = ValueOFArray[Network Engineer/Technical Support]

希望你能帮助我。对不起我无法发布图片。谢谢:)）

Answer 1

$ explode只是一个多维数组，所以：

$query = "SELECT * FROM ticket where workgroup = '".explode[0][0]."';";

您将执行以下查询：

SELECT * FROM ticket where workgroup = 'Technical Support';
