Generate test data for MySQL tables

Test data generation for MySQL using php

Generating test data for MySQL tables is easy and simple.

In this tutorial we are going to see how to insert dummy data in MySQL database using PHP and PDO.
Most of time we need a test data to test or test the performance of the application.

Here is the simple tutorial to generate bulk dummy data using php and Faker PHP Plugin.

Step 1: Download Faker PHP Plugin for Test data generation (Click here)

Step 2: Create MySQL database and tables to insert dummy data into MYSQL using PHP

-- Table structure for table `users`

CREATE TABLE IF NOT EXISTS `users` (

`id` int(11) NOT NULL,

`email` varchar(255) COLLATE utf8_unicode_ci NOT NULL,

`first_name` varchar(75) COLLATE utf8_unicode_ci NOT NULL,

`last_name` varchar(75) COLLATE utf8_unicode_ci NOT NULL,

`created` datetime NOT NULL

) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

-- Indexes for dumped tables

-- Indexes for table `users`

ALTER TABLE `users`

ADD PRIMARY KEY (`id`);

-- AUTO_INCREMENT for dumped tables

-- AUTO_INCREMENT for table `users`

ALTER TABLE `users`

MODIFY `id` int(11) NOT NULL AUTO_INCREMENT;

tep 3: Create test.php file, then include autoload.php file from src directory. That will taking care including Faker classes automatically when we instantiate the Faker class.

Here is my sample script which will make the connection with MySQL database and insert dummy data in it. Specify number of records in $count variable.

<?php
require_once('src/autoload.php');
try{
    $count = 1000;
    $faker = Faker\Factory::create('en_IN');;
    //Connecting MySQL Database
    $pdo  = new PDO('mysql:host=localhost;dbname=fake_data', 'root', '', array(
        PDO::ATTR_PERSISTENT => true
    ));
    $pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
    //Drop the table 
    $stmt = $pdo->prepare("truncate table users");
    $stmt->execute();
    //Insert the data
    $sql = 'INSERT INTO users (first_name, last_name, email, created) 
    VALUES (:first_name, :last_name, :email, :created)';
    $stmt = $pdo->prepare($sql);
    for ($i=0; $i < $count; $i++) {
        $date = $faker->dateTime($max = 'now', 'UTC')->format('Y-m-d H:i:s');
        $stmt->execute(
            [
                ':first_name' => $faker->firstName, 
                ':last_name' => $faker->lastName,    
                ':email' => $faker->email, 
                ':created' => $date
            ]
        );
    }
} catch(Exception $e){
    echo '<pre>';print_r($e);echo '</pre>';exit;
}
?>

<?php

require_once('src/autoload.php');

try{

$count = 1000;

$faker = Faker\Factory::create('en_IN');;

//Connecting MySQL Database

$pdo = new PDO('mysql:host=localhost;dbname=fake_data', 'root', '', array(

PDO::ATTR_PERSISTENT => true

));

$pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

//Drop the table

$stmt = $pdo->prepare("truncate table users");

$stmt->execute();

//Insert the data

$sql = 'INSERT INTO users (first_name, last_name, email, created)

VALUES (:first_name, :last_name, :email, :created)';

$stmt = $pdo->prepare($sql);

for ($i=0; $i < $count; $i++) {

$date = $faker->dateTime($max = 'now', 'UTC')->format('Y-m-d H:i:s');

$stmt->execute(

[

':first_name' => $faker->firstName,

':last_name' => $faker->lastName,

':email' => $faker->email,

':created' => $date

]

);

}

} catch(Exception $e){

echo '<pre>';print_r($e);echo '</pre>';exit;

}

Below Referece for generating different types of dummy data in mysql

Ex:$faker->randomDigit

randomDigit // 7
randomDigitNotNull // 5
randomNumber($nbDigits = NULL, $strict = false) // 79907610
randomFloat($nbMaxDecimals = NULL, $min = 0, $max = NULL) // 48.8932
numberBetween($min = 1000, $max = 9000) // 8567
randomLetter // ‘b’
// returns randomly ordered subsequence of a provided array
randomElements($array = array (‘a’,’b’,’c’), $count = 1) // array(‘c’)
randomElement($array = array (‘a’,’b’,’c’)) // ‘b’
shuffle(‘hello, world’) // ‘rlo,h eoldlw’
