str_replace如何使用数组？ [关闭]

Question

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"]

Answer 1

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.
