Question

I’m doing a print_r on a array stored on a session variable and for some unknown reason it’s adding a number after the array prints.

Example:

Array (     [0] => 868     [userid] => 868 ) 1   

If I do a print_r directly in the function itself and before the variable gets stored on session variable, it doesn’t add that number 1.

Solution:

Almost at the same time as Paolo answered my question correctly I found the causing code.

A simple echo on print_r

Answer 1

Can you post the code you are using to do this around print_r? The most common reason for getting a 1 is when you try to print a boolean:

$my_bool = true; print $my_bool; // will be printed as 1 print_r($my_bool); // will also be printed as 1
