仅将csv值添加到不包含字符串的PHP数组中

I'm trying to create an array of values ($import_data) from a csv file that contains about 42,000 rows, each row contains an SKU. I only want to add the values to the array which DO NOT contain the string "CNV". Is there an easy way to do this?

Here is how I am adding the values from the CSV to the array:

while ( ( $line = fgetcsv($handle, 0, $post_data['import_csv_separator']) ) !== FALSE ) {
            $import_data[] = $line;
        }

This solved it!

         while ( ( $line = fgetcsv($handle, 0, $post_data['import_csv_separator']) ) !== FALSE ) {
            $test_str = print_r($line,true);
            if (strpos($test_str, "CNV") === false){ // add it
            $import_data[] = $line;
         }
