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?

thanks

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' );

?

If you want to print the keys for all the arrays in the main array then 
use allkeys.
