Git is a distributed version control system DVCS designed for efficient source code management, suitable for both small and large projects. It allows multiple developers to work on a project simultaneously without overwriting changes, supporting collaborative work, continuous integration, and deployment. This Git and GitHub tutorial is designed for beginners to learn fundamentals and advanced concepts, including branching, pushing, merging conflicts, and essential Git commands. Prerequisites include familiarity with the command line interface CLI, a text editor, and basic programming concepts. Git was developed by Linus Torvalds for Linux kernel development and tracks changes, manages versions, and enables collaboration among developers. It provides a complete backup of project history in a repository. GitHub is a hosting service for Git repositories, facilitating project access, collaboration, and version control. The tutorial covers topics such as Git installation, repository creation, Git Bash usage, managing branches, resolving conflicts, and working with platforms like Bitbucket and GitHub. The text is a comprehensive guide to using Git and GitHub, covering a wide range of topics. It includes instructions on working directories, using submodules, writing good commit messages, deleting local repositories, and understanding Git workflows like Git Flow versus GitHub Flow. There are sections on packfiles, garbage collection, and the differences between concepts like HEAD, working tree, and index. Installation instructions for Git across various platforms Ubuntu, macOS, Windows, Raspberry Pi, Termux, etc. are provided, along with credential setup. The guide explains essential Git commands, their usage, and advanced topics like debugging, merging, rebasing, patch operations, hooks, subtree, filtering commit history, and handling merge conflicts. It also covers managing branches, syncing forks, searching errors, and differences between various Git operations e.g., push origin vs. push origin master, merging vs. rebasing. The text provides a comprehensive guide on using Git and GitHub. It covers creating repositories, adding code of conduct, forking and cloning projects, and adding various media files to a repository. The text explains how to push projects, handle authentication issues, solve common Git problems, and manage repositories. It discusses using different IDEs like VSCode, Android Studio, and PyCharm, for Git operations, including creating branches and pull requests. Additionally, it details deploying applications to platforms like Heroku and Firebase, publishing static websites on GitHub Pages, and collaborating on GitHub. Other topics include the use of Git with R and Eclipse, configuring OAuth apps, generating personal access tokens, and setting up GitLab repositories.

If you don't want to use serialize() or json_encode() to store the $insData array data to a single column (Key Value Pair) in a MySQL database, you can use a custom delimiter to separate the values and then store the concatenated string in a single column. Here's an example:
// Step 1: Connect to the MySQL database
$servername = "localhost";
$username = "your-username";
$password = "your-password";
$dbname = "your-database";
$conn = mysqli_connect($servername, $username, $password, $dbname);
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
// Step 2: Define the name of the table where you want to store the data
$table_name = "mytable";
// Step 3: Define the delimiter to use
$delimiter = "|"; // Choose any delimiter that won't appear in your data
// Step 4: Concatenate the array values using the delimiter
$data = $insData['uid'] . $delimiter . $insData['first_name'] . $delimiter . $insData['last_name'];
// Step 5: Build the SQL query to insert the data into the table
$query = "INSERT INTO $table_name (mycolumn) VALUES ('$data')";
// Step 6: Execute the query
if (mysqli_query($c, $query)) {
echo "Data inserted successfully!";
} else {
echo "Error inserting data: " . mysqli_error($conn);
}
// Step 7: Close the database connection
mysqli_close($conn);Note that the $delimiter variable is used to separate the array values, and the resulting string is stored in the $data variable. The SQL query uses single quotes to enclose the $data variable, and the resulting string will be stored in a single column in the database.
When retrieving the data from the database, you can use the explode() function to split the concatenated string back into an array:
// Step 1: Connect to the MySQL database
$servername = "localhost";
$username = "your-username";
$password = "your-password";
$dbname = "your-database";
$conn = mysqli_connect($servername, $username, $password, $dbname);
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
// Step 2: Define the name of the table where the data is stored
$table_name = "mytable";
// Step 3: Build the SQL query to retrieve the data from the table
$query = "SELECT mycolumn FROM $table_name";
// Step 4: Execute the query
$result = mysqli_query($conn, $query);
// Step 5: Fetch the result as an array
$row = mysqli_fetch_assoc($result);
// Step 6: Split the concatenated string into an array using the delimiter
$data = explode($delimiter, $row['mycolumn']);
// Step 7: Use the data as needed
echo "User ID: " . $data[0];
echo "First Name: " . $data[1];
echo "Last Name: " . $data[2];
// Step 8: Close the result and the database connection
mysqli_free_result($result);
mysqli_close($conn);Note that the explode() function is used to split the concatenated string retrieved from the database back into an array, using the same delimiter used to concatenate the values. The resulting array can then be used to access the individual values as needed.
