PHP script to import csv data into mysql

Question

I have tried the following code but getting some errors. Here I can read the input file but I am getting the following error:Deprecated: Function split() is deprecated in C:

Answer 1

Several tips:

• Don't use the deprecated ext/mysql, when you can use ext/mysqli or PDO.

• Don't read the entire csv file into a PHP variable. What happens when the file is 500MB?

• Don't write custom PHP code to parse csv data, when you can use the builtin function fgetcsv().

• Don't create a new SQL statement for every row in the data, when you can use prepared statements.

• Don't interpolate data from an external file into SQL statements. This risks SQL injection vulnerabilities, just like when you interpolate untrusted user input.

• Don't parse and insert csv data row by row, when you can use MySQL's LOAD DATA INFILE command. It's 20x faster than inserting row by row.

Here's a simpler solution:

 true,
            PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
        )
    );
} catch (PDOException $e) {
    die("database connection failed: ".$e->getMessage());
}

$affectedRows = $pdo->exec("
    LOAD DATA LOCAL INFILE ".$pdo->quote($csvfile)." INTO TABLE `$databasetable`
      FIELDS TERMINATED BY ".$pdo->quote($fieldseparator)."
      LINES TERMINATED BY ".$pdo->quote($lineseparator));

echo "Loaded a total of $affectedRows records from this csv file.\n";

?>

I tested this with PHP 5.3.26 on a Mac, connecting to MySQL 5.6.14 on Linux.
