MySQL join 4 tables without repetition - php

Question

I have 4 tables and I want to select the information from these tables using one query.
I have a table name
tbl_marketing
db_maid db_client db_status db_process
4 test done ddd
tbl_meeting
db_meetingid db_meetingsubject db_mid
1 test 4
tbl_phonecall
db_phid db_subject db_mid
1 ggg 4
2 fff 4
tbl_email
db_eid db_email db_mid
1 xxx 4
Remark: this is an example of my 4 tables. My tables contain more columns
db_mid is the id of tbl_marketing
I want to select all information without repetition
I use this query:
select
marketing.*,
meeting.db_meetingid,meeting.db_meetingsubject,meeting.db_sd,meeting.db_dd,meeting.db_duration as meetingDuration,meeting.db_place,meeting.db_mom,meeting.db_momattache,meeting.db_status as meetingStatus,meeting.db_nextmeeting,meeting.db_lastmeeting,meeting.db_attendees,meeting.db_note as meetingNote,meeting.db_mid,
phonecall.db_phid,phonecall.db_subject as phoneSubject,phonecall.db_desc as phoneDesc,phonecall.db_nextdate,phonecall.db_doc,phonecall.db_duration as phoneDuration,phonecall.db_phstatus,phonecall.db_pnote,phonecall.db_client as phoneClient,phonecall.db_crf,phonecall.db_callto,phonecall.db_phone as phonecallPhone,phonecall.db_logs as phoneLogs,phonecall.db_mid,phonecall.db_dateedit as phoneEdit,phonecall.db_phdate,
email.db_eid,email.db_edate,email.db_esubject,email.db_edesc,email.db_erf,email.db_emailto,email.db_email as eEmail,email.db_dos,email.db_dor,email.db_estatus,email.db_logs as eLogs,email.db_note as eNote,
location.db_location as location,
location.db_lid,
company.db_company as com,
company.db_coid,
subcompany.db_subid,
subcompany.db_subcompany as sub,
user.db_uid,
concat(user.db_fname,' ' ,user.db_lname) as tr,
subj.db_subjid,
subj.db_subject as s
from tbl_marketing as marketing
left join tbl_location as location
on
marketing.db_location=location.db_lid
left join tbl_meeting as meeting
on
marketing.db_maid=meeting.db_mid
left join tbl_phonecall as phonecall
on
marketing.db_maid=phonecall.db_mid
left join tbl_email as email
on
marketing.db_maid=email.db_mid
left join tbl_company as company
on
marketing.db_companyname=company.db_coid
left join tbl_subcompany as subcompany
on
marketing.db_subcompany=subcompany.db_subid
left join tbl_user as user
on
marketing.db_transfered=user.db_uid
left join tbl_subject as subj
on
phonecall.db_subject=subj.db_subjid
where
marketing.db_maid='$read'
and
meeting.db_mid='$read'
and
email.db_mid='$read'
and
phonecall.db_mid='$read'
I use this query to select the information but when I have 2 rows, the same db_mid as tbl_phonecall in the example, then the information is duplicated as follows:
table marketing
1 test 4
1 test 4
table phonecall
1 ggg 4
2 fff 4
table meeting
1 test 4
1 test 4
table email
1 xxx 4
1 xxx 4
As visible above all tables have a duplicate value without phonecall because he have 2 rows I want to show all the information without this repetition
if I use group by mid I don't receive the second information in tbl_phonecall
$rows=array();
while($rows=mysqli_fetch_array($sql)){
$row[]=$rows;}
<table>
foreach($rows as row){
<tr>
<td><?php echo $row['phID'];?></td>
</tr>
}
</table>
output
# subject mid
1 test 4
2 ggg 4
not like this
1,2 test,ggg 4,4

If you only have duplicates in the phonecall table, the following should work. If other left joined tables can have duplicates, just add GROUP_CONCAT as needed.
select
marketing.*,
meeting.db_meetingid,
meeting.db_meetingsubject,
meeting.db_sd,
meeting.db_dd,
meeting.db_duration as meetingDuration,
meeting.db_place,
meeting.db_mom,
meeting.db_momattache,
meeting.db_status as meetingStatus,
meeting.db_nextmeeting,
meeting.db_lastmeeting,
meeting.db_attendees,
meeting.db_note as meetingNote,
meeting.db_mid,
GROUP_CONCAT(phonecall.db_phid) as phID,
GROUP_CONCAT(phonecall.db_subject) as phoneSubject,
GROUP_CONCAT(phonecall.db_desc) as phoneDesc,
GROUP_CONCAT(phonecall.db_nextdate) as phNextDate,
GROUP_CONCAT(phonecall.db_doc) as phDoc,
GROUP_CONCAT(phonecall.db_duration) as phoneDuration,
GROUP_CONCAT(phonecall.db_phstatus) as phStatus,
