MySql Loop through a column to form concatenated string - php

Question

I am new to SQL and PHP. I have a requirement where the end user enters text in an HTML form, which I am storing in MySQL db. Later I query all the tables in the db which has the user data to obtain concatenated strings.
For a clearer understanding here is an image of my data and the desired result: Click for Image
Right now I am able to concatenate only one string based on a specific id with this query:
select group_concat(text order by T.did separator ' ') as TTT
from (
select l.dimgroupid as did, d.*, l.dimlevelid as id, l.dimlevelvalue,
concat(d.dimensiontext," ",l.dimlevelvalue) as text
from dimensionlevel l
join dimension d on d.dimensionid = l.dimid
join dimensiongroup g on g.groupid = l.dimgroupid) as T
where T.id=0;
which gives me the result
| TTT |

I know I can use a loop on id, but the problem is the ids are not fixed.
Note: There can be "n" number of dimensions and levels.
Here is an SQL Fiddle of the data I am trying to query: SQL Fiddle

I have edited your query to get what you wanted..
select did as groupid, group_concat(text order by dimensionid separator ' ' ) as TTT
from (
select l.dimgroupid as did, d.*, l.dimlevelid as id, l.dimlevelvalue, concat(d.dimensiontext," ",l.dimlevelvalue) as text
from dimensionlevel l
join dimension d on d.dimensionid = l.dimid
join dimensiongroup g on g.groupid = l.dimgroupid
) as T
group by id;
I hope this helps you...
UPDATE :
using php..
$sql = "SELECT `dimensionid`, `dimensiontext`, `dimensiondescr` FROM `dimension`";
$dimensions = mysqli_fetch_all (mysqli_query($con, $sql));
$sql = "SELECT `dimlevelvalue` FROM `dimensionlevel` WHERE dimid IN (SELECT dimensionid FROM dimension WHERE dimensiondescr='age') ";
$ages = mysqli_fetch_all (mysqli_query($con, $sql));
$sql = "SELECT `dimlevelvalue` FROM `dimensionlevel` WHERE dimid IN (SELECT dimensionid FROM dimension WHERE dimensiondescr='sex') ";
$sexes = mysqli_fetch_all (mysqli_query($con, $sql));
$sql = "SELECT `dimlevelvalue` FROM `dimensionlevel` WHERE dimid IN (SELECT dimensionid FROM dimension WHERE dimensiondescr='experience') ";
$experiences = mysqli_fetch_all (mysqli_query($con, $sql));
foreach ($ages as $age) {
foreach ($sexes as $sex) {
foreach ($experiences as $exp) {
foreach ($dimensions as $dimension) {
$putage = "";
$putsex = "";
$putexp = "";
if($dimension[2]=="Age"){
$putage = $age[0];
}elseif($dimension[2]=="Sex"){
$putsex = $sex[0];
}elseif($dimension[2]=="Experience"){
$putexp = $exp[0];
}
echo $str = $dimension['1']." ".$putage.$putsex.$putexp." " ;
}
echo "<br>";
}
echo "<br>";
}
}
