Check if exist in array (all in foreach)

Hi!
I have little problem.
I need to check every row in another array, and if exist - do something.

This is my code:

PHP Code:

<?php $Sekcje = explode( ',', $Detail->SectionsPrefered ); ?>
                        <?php foreach ($SectionsList as $SectionOption): ?>
                                <div class="checkbox">
                                    <?php if ( in_array( $SectionOption->Title , $Sekcje ) ): ?>
                                        *
                                    <?php endif ?>
                                    <label>
                                        <input type="checkbox" value="<?php echo $SectionOption->Title; ?>">
                                        <?php echo $SectionOption->Title; ?>
                                    </label>
                                </div>
                        <?php endforeach ?>

It's display only one '*', but must display for 3 rows (Section1, Section2, Section3)

This is the array $Sekcje:

PHP Code:

array(3) { 
       [0]=> string(8) "Section1" 
       [1]=> string(9) " Section2" 
       [2]=> string(9) " Section3" 
} 


Where is the problem?
