Question

I have the following line in a php file:

$labels['study'] = 'Study';

Then, I include that file in my index page to print the value. It gets the value but instead of printing “Study”, it prints ” Study” (with a blank at the beginnig).
I’ve tried aplying trim() to the returned value and in other places but it has no effect.

The way I’m returning the value is:

<?=get_label('study')?>

There is always a blank (or other blank characters) at the beginning.

I’m wondering why this happens. Any idea?

The get_label function is this:

function get_label($texto){
    require("lang/".$_SESSION['lang'].".php");
    $traduccion = trim($labels[$texto]);
    if($traduccion == '')
        return '['.$texto.']';
    else
        return $traduccion;

And the code above and below where I call the function:

<div>
    <h2><?=get_label('Estudio')?></h2>
    <?=get_text('estudio');?></div> 
</div>

I’ve tried with all of it in the same line (from to ) and it neither works.

You probably have a space in the HTML code before the <?= tag, not in the PHP variable.

If that’s not a space, it could be a new line as well (in the HTML).
