Question: How to remove duplicate values in a PHP array? Answer: - Use the array_unique function
- array_unique (PHP 4 >= 4.0.1, PHP 5)
- array_unique (Takes an input array and returns a new array without duplicate values)
- array_unique (array $array [, int $sort_flags=SORT_STRING ] )
Example:
CODE:
<?php //Array with duplicate values
$array = array("test","test1","test","sum","minus","max","max","max","min"); //Removing duplicate values
$newArray = array_unique($array); echo '<pre>';
print_r($newArray);
?>
OUTPUT:
//The above code will produce the following results without the duplicate values
Array
(
[0] => test
[1] => test1
[3] => sum
[4] => minus
[5] => max
[8] => min
)
