PHP While Loops from Arrays
I have a table that contains members names and a field with multiple ID numbers. I want to create a query that returns results where any values in the ID fields overlap with any values in the array.
For example: lastname: Smith firstname: John id: 101, 103
I have Array #1 with the values 101, 102, 103
I want the query to output all members who have the values 101 or 102 or 103 listed in their id field with multiple ids listed.
Array ( [0] => 101
[1] => 102
[2] => 103 )
$sql="SELECT firstname, lastname, id
FROM members WHERE id LIKE '%".$array_num_1."%'";
$result=mysql_query($sql);
while ($rows=mysql_fetch_array($result)) {
echo $rows['lastname'].', '.$rows['firstname'].'-'.$rows['id'];

I tried to simplify it. The IDs are actually stored in another table, and I have generated the array from this table.
$array_num_1 = array();
$sql_id="SELECT id FROM id_table WHERE id < 200";
$result_id=mysql_query($sql_id);
while($rows_id=mysql_fetch_array($result_id)){;
$array_num_1[] = $rows_id['id'];
}
Normalize your database. Make these ids into separate table.
Edit: And then use answers below
If you must do it this way:
$sql = "SELECT firstname, lastname, id FROM members WHER id IN (" . implode(', ', $array) . ")"
As @cletus says in his comment, though, the database is made for this sort of thing. Hard coding it in an array seems like the suboptimal way of doing things.
You're probably looking for IN
:
SELECT firstname, lastname, id FROM members WHERE id IN (1, 2, 3);
Of course, you could create (1, 2, 3)
dynamically, e.g. using implode.
Whoops, I just realized that I got your db schema wrong. As others have advised, you should normalize it.
SELECT firstname, lastname, m.id
FROM members m, id_table i ON m.id=id_name
WHERE i.id < 200
