//If you have to catch the output without showing it at all at first (for example, if you want to append the //print_r output to a file), you can do this:



ob_start();
print_r( $some_array );
$output = ob_get_clean();

// if you want to append the print_r output of $some_array to, let's say, log.txt:

file_put_contents( 'log.txt', file_get_contents( 'log.txt' ) . $output )
