Note Submitter: xp_sim at hotmail dot com ---- Ray dot Paseur at SometimesUsesGmail dot com : You might also want to try array_count_values. This function returns the number of repetitions for each value in the array. Then, you sort the resulting array in descending order and parse it using a "foreach" to get all the values that are present more than once in the original array. Ex. : <?php //From your code $raw_array = array(); $raw_array[1] = 'abc@xyz.com'; $raw_array[2] = 'def@xyz.com'; $raw_array[3] = 'ghi@xyz.com'; $raw_array[4] = 'abc@xyz.com'; // Duplicate //Count the no. of repetitions $count_by_value = array_count_values( $raw_array ); //Sort in asc. order natcasesort( $count_by_value ) //Reverse order (desc.) $count_desc = array_reverse( $count_by_value ); $not_uniques = array(); foreach( $count_desc as $orignal_value => $count){ //Exit loop if only uniques remain if( $count == 1 ){ break; } //Add current value to the output array $not_uniques[] = $orignal_value; } print_r($not_uniques); ?> What do you think ?
