Concatenating two variables with an underscore

I want the output to be concatenating the two variables I have. The $out [1] is now echo: /home/data/main/folders/folder1/size1

The $arr[$folder_name] [1] is echo folder1

I want the echo for $newfoldername to be /home/data/main/folders/folder1/size1_folder1

$newfoldername = $out [1] . '_'  $arr[$folder_name];
echo $out [1] ;
echo $arr[$folder_name] [1] ;
rename ( $out [1] ,  $newfoldername  ) ;

This was the correct solution for me:

$newfoldername = substr( $out [1], 0, -1 )  .  "_"  .  $arr[$folder_name];

For short you can just:

rename ($out[1], $out[1].'_'.$arr[$folder_name] );

Or echo that:

echo $out[1].'_'.$arr[$folder_name];

Careful with syntax when sharing problems, it might be the source of the problem. But your IDE should have showed you.

I do not understand the question, but you have mistake in this string

$newfoldername = $out [1] . '_' $arr[$folder_name];

take this code. it is whithout mistakes;

$newfoldername = $out [1] . '_' .  $arr[$folder_name];
