mysql - How to set a variable in where clause of Select query in php -

-

while executing below query i'm not getting sucess value 

$name=qwe; $result = mysql_query("select *from user name = $name");

instead of above query if put below, can able appropriate ans: 

$result = mysql_query("select *from user name = 'qwe'");

can give solution first query??

close variable in quote , concatenate string query

$name= "qwe"; $result = mysql_query("select *from user name = '".$name."'");

one more note please use mysqli security purposes. thanks
