Only add csv values to PHP array that do not contain string -

i'm trying create array of values ($import_data) csv file contains 42,000 rows, each row contains sku. want add values array not contain string "cnv". there easy way this?

here how adding values csv 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             $import_data[] = $line;          }
