create array with foreach() result on PHP

Question

I'm trying for two days to create an array with the result of a mysql query as values ​​to prevent a appears:

foreach($achievements as $acvhm2){
    if(!array_key_exists(($acvhm2['key'] - 19999 ), $achievements)){
        if($acvhm2['key'] - 20000 == $tam){
        $san .= $tam.',';
        $san1 = substr($san, 0, -1);
        }
    }
}

$orgly2 = array($san1);

if(!in_array($tam, $orgly2)){
echo ' <tr><td style="opacity:.64;">... ';
}

but it doesn't work for all the < tr > that I got on results...

when I do the array manually everything works perfectly:

$orgly2 = array(3,5,13);

all results where $tam is equal to one of the numbers in the array are left with opacity 64.

anyone have any idea what is wrong in my code?

Answer 1

I think you're looking for explode() :

$orgly2 = explode(',',$san1);

You were basically creating an array with one argument that is a string with commas that would look something like this:

$orgly2 = array('3,5,13');
