PHP - csv in_array function check

Question

I am trying to pass if() statement with !in_array() check for the generated csv file.

End result is returning false for some reason, and I can not find what am I doing wrong. I am trying to pass false statement and continue with code execution.

Input:

• Array with data I want to put into csv file.

• Creating and inputing data into file.

• Getting the file

     $list = [
            0 => [
                'materials'
            ],
            1 => [
                'products'
            ]
        ];
  
     $testCsvFile = fopen("test.csv", "w");
     foreach ($list as $fields) {
          fputcsv($testCsvFile, $fields);
      }
  
    $projectRoot = substr(strrchr(getcwd(), DIRECTORY_SEPARATOR), 1);
    $getFile = $projectRoot . '/test.csv';
    $file = basename($getFile);
  
    if ($list && is_array($list)) {
        unset($parsed_data[0]);
    }
    if (!in_array($file, ['materials', 'products'])) {
        return false;
    }
  
  .... next //

you're searching the strings without reading the file you should first open the file , read it then you should find string in array, I've pasted below code just for your reference which is searching the string in csv file after opening and reading.

$file = fopen("test.csv", "r");
$str = "materials";
while (($data = fgetcsv($file)) !== false)
{
    if(in_array($str, $data))
    {
        foreach ($data as $i)
        {
            echo $i."<br>";
        }   
    }
}
fclose($file);
