How to print elemnets of N-dimensional array?

[opt_inf_env@yahoo.com]

Hello,

What is a common way to print elements of a multidimensiona l array? I
treid to do it in the straightforward way:
$input_list[0][0] = "Something" ;
print "$input_lis t[0][0]";
And it does not work.

The solution that I found is to use intermediate variable:
$array = $input_list[0];
print "$array[0]";
printArray( $output_list[0] );

Are there any more elegant (or just common) ways to do it?

Either one of the following should work:

print $input_list[0][0];
print "{$input_li st[0][0]}";

Notice the braces used in the second example.

You're close. PHP automatically expands variables inside of quotation
marks. Thus, when you write

print "$input_lis t[0][0]";

PHP sees this as a string because it's in quotation marks, and attempts
to replace the text "$input_lis t" with the value of the $input_list
variable. In this case, $input_list is an array, and trying to print or
echo an array by name results in the string "Array."

To solve this problem, just remove the quotation marks:

print $input_list[0][0];

Or, if you need to print the value embedded in a string, do this:

print "{$input_li st[0][0]}";
