The issue of duplicated values in a PHP foreach loop with an associative array fetched from Mysqli can be caused by several factors, including:
Inconsistent casing of array keys: If the array keys have different casing, the foreach loop may interpret them as separate keys, even though they represent the same value.
Mismatched data types: If the data types of the array values are not consistent, the foreach loop may not be able to correctly identify duplicate values.
Improper use of the arrayunique() function: If the arrayunique() function is not used correctly, it may not remove all the duplicate values from the array.
Incorrect use of the mysqlifetchassoc() function: If the mysqlifetchassoc() function is not used correctly, it may fetch duplicate rows from the database, resulting in duplicate values in the array.
To solve this issue, it is important to ensure that the array keys are consistently cased, the data types of the array values are consistent, the arrayunique() function is used correctly, and the mysqlifetch_assoc() function is used properly to fetch unique rows from the database.
