Remove Duplicate Elements from the Array<\/em><\/strong><\/figcaption><\/figure>\n<\/div>\n\n\n

In this query, we will discuss How to remove duplicate elements from an array in PHP. We can get the unique elements by using array_unique() function. This function will remove the duplicate values from the array.<\/p>\n\n\n\n

Parameters: This function accepts two parameters that are discussed below:<\/p>\n\n\n\n

  • $array:<\/strong> This parameter is mandatory to be supplied and it specifies the input array from which we want to remove duplicates.<\/li>
  • $sort_flags<\/strong>: It is an optional parameter. This parameter may be used to modify the sorting behavior using these values:<\/li>
  • SORT_REGULAR:<\/strong> This is the default value of the parameter $sort_flags. This value tells the function to compare items normally (don\u2019t change types).<\/li>
  • SORT_NUMERIC<\/strong>: This value tells the function to compare items numerically.<\/li>
  • SORT_STRING:<\/strong> This value tells the function to compare items as strings.<\/li>
  • SORT_LOCALE_STRING:<\/strong> This value tells the function to compare items as strings, based on the current locale.<\/li>
  • Return Value:<\/strong> The array_unique() function returns the filtered value after removing all duplicates from the array.<\/li><\/ul>\n\n\n\n

    Example: PHP program to remove duplicate values from the array.<\/p>\n\n\n\n

    <?php\r\n  \r\n\/\/ Input Array\r\n$a = array(\"circle\", \"square\", \"circle\", \"triangle\");\r\n  \r\n\/\/ Array after removing duplicates\r\nprint_r(array_unique($a));\r\n  \r\n?><\/code><\/pre>\n\n\n\n
    Output
    Array
    (
    [0] => circle
    [1] => square
    [3] => triangle
    )<\/p>\n\n\n\n
    Example: PHP program to remove duplicate elements from an associative array.<\/p>\n\n\n\n
    <?php\r\n  \r\n\/\/ Input array\r\n$arr = array(\r\n      \"a\" => \"BH\", \r\n      \"b\" => \"CK\", \r\n      \"c\" => \"CK\", \r\n      \"d\" => \"AND\"\r\n);\r\n  \r\n\/\/ Array after removing duplicates\r\nprint_r(array_unique($arr));\r\n  \r\n?><\/code><\/pre>\n\n\n\n
    Output
    Array
    (
    [a] => BH
    [b] => CK
    [d] => AND
