DQL with between – string date – PHP

I am trying to do a sql with between. The date data is entered first as a string. Any help with this question?

Answer

The string is dd/mm/yyyy

$var = '28/09/2021';
$date = str_replace('/', '-', $var);
$fecha_inicio=date('Y-m-d', strtotime($date));
//dd($fecha_inicio);

At the final you will get date like 2021-09-28 and now we can do a between with actual date 2021-10-01

select t from AppEntitytable1 t, AppEntitytable2 s where s.id=t.id and s.id=50 AND (s.fecha_solicitud BETWEEN ('2021-09-28') AND ('2021-10-01') ) order by s.field1  asc, s.field2  asc, s.field3  asc

after this you can see the sentence in DB with dd($query->getSQL()); function

SELECT 
  a0_.*, 
FROM 
  tabla1 a0_, 
  tabla2 s1_ 
WHERE 
  s1_.id = a0_.id 
  AND s1_.id = 23 
  AND (
    s1_.fecha_solicitud BETWEEN ('2021-09-28') 
    AND ('2021-10-01')
  )   
ORDER BY 
  s1_.field1 ASC, 
  s1_.field2 ASC, 
  s1_.field3 ASC
