why not worked str_replace? what do i do?

$date = $this->convert_date->JalaliToGregorian('1390','04','20'); ->> this output with json_encode -> [2011,7,11]
$da =  str_replace(",","/",$date);
echo json_encode ($da) ->> output  Array ["2011","7","11"]

The commas are not in the array. That's being added by json_encode. Try implode("/", $date); That will combine the three array elements using / as glue.

json_encode returns a string which represents the JSON representation of an object. In the case of Arrays, that is a comma delineated list surrounded by commas. If you want to have the array be delineated by something else, then you should use implode($glue,$pieces).

implode("/", $date);

As a bit of a gotcha -- implode will work based on key insertion order so you may want to use ksort first:

$a = array(1=>1, 0=>0); 
echo implode(",", $a); // outputs 1,0
ksort( $a );
echo implode(",", $a); // outputs 0,1

---

I'am not entirely sure what do you expect as a result. If you want your script to output '2011/7/11', then you shoul use implode() instead of str_replace (since $date is not a string, but an array). So

$da = implode('/', $date);

would give you that result

---

I am not sure, whether I understand you correctly, but this may be a solution:

echo implode('/', $date);

This will glue the elements of $date array with / into this string:

2011/7/11
