This is the most important technique for all Php developers because of Mysql can't store the array values directly.
So we need to convert the PHP Array to string by using the serialize().
This mechanism is very useful in the e-commerce cart functionality. For example, we can store the customer purchase items list and price can be stored in the associative array and convert into string and store in the MySQL.
This way we can reduce the logic of the code get the accurate result also.

MySql Code
CREATE TABLE `students` ( `id` int(11) NOT NULL, `language` varchar(50) NOT NULL, `student_names` mediumtext NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1; -- -- Indexes for table `students` -- ALTER TABLE `students` ADD PRIMARY KEY (`id`); -- -- AUTO_INCREMENT for table `students` -- ALTER TABLE `students` MODIFY `id` int(11) NOT NULL AUTO_INCREMENT;You need to connect the database create the dbconfig.php file
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "techiesbadi";
// Create connection
$con = new mysqli($servername,$username, $password, $dbname);
// Check connection
if ($con->connect_error) {
die("Connection failed: " . $con->connect_error);
}
?>
Now Store the PHP Array in MySql create the store-array.php file
<?php
include "dbconfig.php";
$students = array("ramu", "ravi", "gopal", "krishna");
//Converting array to String
$student_names=mysqli_real_escape_string($con, serialize($students));
$sql = "INSERT INTO `students` (`id`, `language`, `student_names`) VALUES (NULL, 'php', '$student_names')";
$result = $con->query($sql);
if($result === TRUE){
echo "Record inserted successfully";
}
?>
Now retrieve the PHP Array from MySQL create the retrieve-array.php file
<?php
include "dbconfig.php";
$getStudnets = $con->query("SELECT * FROM `students` LIMIT 1");
$studentsData = $getStudnets->fetch_object();
$language = $studentsData->language;
//Converting string to array
$students = unserialize($studentsData->student_names);
//printing students array
print_r($students);
echo "<br />";
foreach ($students as $student) {
echo $student." learning ".$language." language.<br/>";
}
?>
