How to remove duplicate values from an array in PHP
Use array_unique().
Example:
$array = array(1, 2, 2, 3);$array = array_unique($array); // Array is now (1, 2, 3)
Use array_values(array_unique($array));
array_unique: for unique arrayarray_values: for reindexing
//Find duplicates $arr = array( 'unique', 'duplicate', 'distinct', 'justone', 'three3', 'duplicate', 'three3', 'three3', 'onlyone' );$unique = array_unique($arr); $dupes = array_diff_key( $arr, $unique ); // array( 5=>'duplicate', 6=>'three3' 7=>'three3' )// count duplicatesarray_count_values($dupes); // array( 'duplicate'=>1, 'three3'=>2 )
