PHP print json_encode initial line break

Question

I am using phpunit to do some testing and I ran into a problem with

print json_encode($assoc_array);

I have an associative array

$assoc_array("username":"xxx");

In my_function() I print it out like this

print json_encode($assoc_array);

Then in my phpunit test I assert this

$output=my_function($assoc_array);
$expected='{"username":"xxx"}';
$this->assertEquals($expected,$output);

The assert returns false because $output is

$output='
{"username";"xxx"}';

and $expected is

$expected='{"username";"xxx"}';

For some reason I am getting a line break at the beginning when I use print json_encode();

I could just add a line break to all of my $expected values, but I really don't want to do that. Why am I getting the line break? Can anyone else get the line break too?

I don't get a line break. Are you sure there's no other line break earlier in your script? Maybe you have a blank line before <?php? — Barmar

@KrishR What difference does that make? echo and print work the same way. — Barmar

Try print '|' . json_encode($assoc_array);. Is the line before before or after |? — Barmar

Thanks for the help @Barmar. I found a line break after a ?> in a controller. I will remove all the ?> from the class files.
