How to Insert a PHP Array into a MySQL Database?

Inserting Arrays into MySQL Databases with PHP

Question:

How can I insert an array into a MySQL database using PHP?

Answer:

Inserting an array directly into MySQL is not possible as MySQL only recognizes SQL statements. To store the array, it must first be converted.

Conversion and Insertion Process:

1. Extract Array Information:

   • Extract the keys (column names) and values from the array.

2. Create SQL Statement:

   • Construct an INSERT statement with the column names and values as follows:

     • INSERT INTO table_name (column1, column2, ...) VALUES (value1, value2, ...)

3. Secure Input:

   • Escape special characters from the array values to prevent SQL injection.

4. Convert Array to SQL String:

   • Implode the array of column names and escaped values using a specified separator.

5. Execute the INSERT Query:

   • Connect to the database and execute the generated SQL statement using a database library like mysqli.

Example Code:

Assuming you have a table named fbdata with columns corresponding to the array keys, the following code snippet demonstrates the process:

// Extract array information
$columns = implode(", ", array_keys($insData));

// Connect to the database
$link = mysqli_connect($url, $user, $pass, $db);

// Escape array values
$escaped_values = array_map(array($link, 'real_escape_string'), array_values($insData));

// Implode escaped values into a string
$values = implode("', '", $escaped_values);

// Construct the INSERT statement
$sql = "INSERT INTO `fbdata`($columns) VALUES ('$values')";

// Execute the query
mysqli_query($link, $sql);
