in_array unexpected results

Hello I have an array that looks likes this,

    Array
(
    [0] => 40's
    [1] =>  50's
    [2] =>  60's
)

and some code that looks like this, 

<?php if(isset($playable_age) && in_array('40\'s', $playable_age)) { $set = TRUE; } else { $set = FALSE; } ?>
<div class="checkbox"><?php echo $this->formbuilder->checkbox( 'playable_age[]', "40's", "40's", $set ); ?></div>
<?php if(isset($playable_age) && in_array('50\'s', $playable_age)) { $set = TRUE; } else { $set = FALSE; } ?>
<div class="checkbox"><?php echo $this->formbuilder->checkbox( 'playable_age[]', "50's", "50's", $set ); ?></div>
<?php if(isset($playable_age) && in_array('60\'s', $playable_age)) { $set = TRUE; } else { $set = FALSE; } ?>
<div class="checkbox"><?php echo $this->formbuilder->checkbox( 'playable_age[]', "60's", "60's", $set ); ?></div>

Now the first if statement returns true, however the 2nd and 3rd if return false even though the 50's and 60's values exist in the array why is this?

Because you have a syntax error.

You can do this:

<?php 
$playable_age = array(0=>'40\'s',1=>'50\'s',2=>'60\'s');
if(isset($playable_age) && in_array('40\'s', $playable_age)) { $set = TRUE; echo "1"; } else { $set = FALSE; echo "2"; } 
if(isset($playable_age) && in_array('50\'s', $playable_age)) { $set = TRUE; echo "3"; } else { $set = FALSE; echo "4"; } 
if(isset($playable_age) && in_array('60\'s', $playable_age)) { $set = TRUE; echo "5"; } else { $set = FALSE; echo "6"; } 
if(isset($playable_age) && in_array('70\'s', $playable_age)) { $set = TRUE; echo "7"; } else { $set = FALSE; echo "8"; } 
?>

Before you perform logic checks on the array, create a user-defined function and call it with array_walk to trim() on each array value.

Looks like there is a space before these values in the array:

[1] =>  50's
[2] =>  60's
       ^

Something not seen with the first value:

[0] => 40's
