Question

I have a large SQL file I’m trying to insert into the database. It wouldn’t work via phpMyAdmin since it was so large, so I created a custom script:

<?php

ini_set('max_execution_time', 0);

$file = file_get_contents('./mySQLfile.sql');

//var_dump($file); die();

$conn = new mysqli('localhost', 'myUserName', 'myPassword', 'myDatabase');

$q = $file;

if ($result = $conn->query($q))
{
    echo '<font color="red">'.$conn->error.'</font>';
    echo '<br />';
}

?>

The file var_dump()’s properly. The connection to the database is created (I’ve tested it by returning values from the database). However, when I run the code, no data is inserted into the database. The beginning of the SQL file is as follows:

-- phpMyAdmin SQL Dump
-- version 3.4.5
-- http://www.phpmyadmin.net
--
-- Host: localhost
-- Generation Time: Dec 05, 2012 at 04:01 PM

-- PHP Version: 5.3.8

SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";
SET time_zone = "+00:00";


/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;

  PRIMARY KEY (`vid`,`delta`),

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT INTO `content_field_image_cache` (`vid`, `nid`, `delta`, `field_image_cache_fid`, `field_image_cache_list`, `field_image_cache_data`) VALUES
(1000, 1000, 0, 1000, 1, NULL),
(1001, 1001, 0, 1001, 1, NULL),
(1002, 1002, 0, 1002, 1, NULL),

Why won’t these values get inserted?

Thanks.

PHP’s mysql driver (mysql/mysqli/pdo) doesn’t allow multiple queries in a single call as a security measure. You cannot feed an entire dump into a single query call like that.

You’d be better off simply doing something like

exec("mysql -u xxx -p < dump.sql");

instead.
