hello, I have a simple question, not really a problem this time. I know that the function print_r() will print an array but if that array has sub-arrays it prints everything and if you don't use more command or a pipe of some kind that could be useless in some cases, but I am just wondering, for an array that has several arrays in it, is there a way to print the array names that are contained in the "main array" but not the contents of each?Note: untested code, and this preserves keys, which you might not want. It's reasonably simple to change it to not preserve keys. <?php $array = array( 'this', 'is', 'my', array( 'array' ) ); $newArray = array(); foreach( $array as $key=>$value ) { if( !is_array( $value ) ) { $newArray[$key] = $value; } } print( '<pre>' . print_r( $newArray, true ) . '</pre>' ); ?> -- Jasper Bryant-Greene Freelance web developer http://jasper.bryant-greene.name/ If you find my advice useful, please consider donating to a poor student!
