Hi friends, in this tutorial you will learn how to perform a PHP MySQL search database and display results in a step-by-step process from scratch. We must know that database searching is very useful in any kind of application or in any dynamic website. Therefore, we can do this with the help of a PHP script and get the desired results based on the search input from HTML forms.
Steps to perform PHP MySQL search database and display results
Step 1:- Create a database in PHP Myadmin as shown in the below screenshot.
Step 2:- Create a table in the database as shown in the below screenshot.
Step 3:- Insert data in the table.
In this step, we will insert some data with the help of an SQL query so that we can search from these data and show the results later as shown below
Query example for inserting data:- INSERT INTOemployee_info(id,name,phone_no,age,department,created_at,updated_at) VALUES (NULL, 'ABC', '1234567891', '25', 'IT', current_timestamp(), '0000-00-00 00:00:00.000000');
Now, you can see the inserted data as shown below
Step 4:- Create a PHP file and Make an HTML form
In this step, we will create an HTML form with a search element so that we can enter the search input as shown below
Step 5:- Create a PHP file and establish the database connection as shown below
coonnect_test_db.php:-
<?php
$servername='localhost';
$username="root";
$password="";
try
{
$con=new PDO("mysql:host=$servername;dbname=test_db",$username,$password);
$con->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
//echo 'connected';
}
catch(PDOException $e)
{
echo '<br>'.$e->getMessage();
}
?>
Step 6:- Write a PHP script based on the search input.
<?php
include 'connect_test_db.php';
$searchErr = '';
$employee_details='';
if(isset($_POST['save']))
{
if(!empty($_POST['search']))
{
$search = $_POST['search'];
$stmt = $con->prepare("select * from employee_info where department like '%$search%' or name like '%$search%'");
$stmt->execute();
$employee_details = $stmt->fetchAll(PDO::FETCH_ASSOC);
}
else
{
$searchErr = "Please enter the information";
}
}
?>
Below are the two examples of searching data from the database
- If the search input is matched with the column value and the column has the single value then it will return the single row as shown in the below screenshot.
- If the search input is matched with the column value and the column has more than one value then it will return multiple rows as shown in the below screenshot.
Complete Code:- phpsearch.php
<?php
include 'connect_test_db.php';
$searchErr = '';
$employee_details='';
if(isset($_POST['save']))
{
if(!empty($_POST['search']))
{
$search = $_POST['search'];
$stmt = $con->prepare("select * from employee_info where department like '%$search%' or name like '%$search%'");
$stmt->execute();
$employee_details = $stmt->fetchAll(PDO::FETCH_ASSOC);
//print_r($employee_details);
}
else
{
$searchErr = "Please enter the information";
}
}
?>
