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 ? ---- Server IP: 66.207.199.35 Probable Submitter: 207.96.178.150 ---- Manual Page -- http://www.php.net/manual/en/function.array-unique.php Edit -- https://master.php.net/note/edit/81701 Del: integrated -- https://master.php.net/note/delete/81701/integrated Del: useless -- https://master.php.net/note/delete/81701/useless Del: bad code -- https://master.php.net/note/delete/81701/bad+code Del: spam -- https://master.php.net/note/delete/81701/spam Del: non-english -- https://master.php.net/note/delete/81701/non-english Del: in docs -- https://master.php.net/note/delete/81701/in+docs Del: other reasons-- https://master.php.net/note/delete/81701 Reject -- https://master.php.net/note/reject/81701 Search -- https://master.php.net/manage/user-notes.php
