Using a slightly modified array that you posted, I came up with this in about 10 minutes <pre>I am working with the following data structure <?php $in = array( 0 => array( 0 => array('Flight Number', 'flight_number'), 1 => array( 0 => array('Timestamp Departure', 'timestamp_departure'), 1 => array('Timestamp Arrival', 'timestamp_arrival'), ) ), 1 => array('Departure City', 'departure_city'), 2 => array('Arrival City', 'arrival_city'), ); print_r($in); echo "\n\n"; $max_depth = 0; $cur_depth = 0; function max_array_depth($ar) { global $cur_depth, $max_depth; if ( is_array($ar) ) { $cur_depth++; if ( $cur_depth > $max_depth ) { $max_depth = $cur_depth; } foreach ( $ar AS $row ) { max_array_depth($row); } $cur_depth--; } } max_array_depth($in); echo "Max depth of array is: {$max_depth}"; ?></pre> http://www.cmsws.com/examples/php/testscripts/daevid@xxxxxxxxxx/0002.php -- Jim Lucas NOC Manager 541-323-9113 BendTel, Inc. http://www.bendtel.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
