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>' );
?>
