should help you out The notice should give you a line number, Can you provide it.
In your query, You should update this line:
code :
    WHERE media.project_id = '$project->id'
    WHERE media.project_id = '{$project->id}'
$project->primary_image = $primary_image[0];
$primary_image = dbSelect($db, $query);
var_dump($primary_image);
$project->primary_image = $primary_image[0];

I wish this helpful for you
I still don;t understand. Should I do an if preg_match to avoid this?
code :
$pattern2 = "/([A-Za-z0-9\.\-\_\!\#\$\%\&\'\*\+\/\=\?\^\`\{\|\}]+)\@([A-Za-z0-9.-_]+)(\.[A-Za-z]{2,5})/";

foreach ($lines as $email) {
    if( preg_match($pattern2,$email,$goodies) ) {
        $goodies[0]=filter_var($goodies[0], FILTER_SANITIZE_EMAIL);
        if(filter_var($goodies[0], FILTER_VALIDATE_EMAIL)){
            array_push($good,$goodies[0]);
        }
    }
}

seems to work fine You should always initialize your variables. This is absolutely a best practice across virtually every language, and it's considered an extremely bad habit to access unset variables. You should always be developing software with errors on.
Your code should read:
code :
$arr['var1'] = $arr['var2'] = 0;
for($i = 0; $i<10; $i++)
{
    $arr['var1'] += $val1[$i];
    $arr['var2'] += $val2[$i];
}

Hope this helps I manually fixed the BigInteger and I remained only with the sso.log.
Dug into it and I found that there was another module error blocking customer login. Setting that module to false in app/etc/modules/Module_Name.xml fixed it.

it helps some times You $types array only has 4 elements, there is no index 4.
Use modulo 4 to make sure the number never goes over 3 and keeps looping from 0 to 3.
code :
"type" => $types[$i % 4],
