What potential issues can arise from the double representation of a table in PHP code?

Potential issues that can arise from the double representation of a table in PHP code include data inconsistency and increased maintenance overhead. To solve this issue, it is best to create a single source of truth for the table structure and data, and then use this source consistently throughout the code. 

// Define the table structure in a separate file
// table_structure.php
$tableStructure = [
    'id' => 'INT(11) PRIMARY KEY',
    'name' => 'VARCHAR(255)',
    'age' => 'INT(3)',
    // Add more columns as needed
];

// Use the table structure in your PHP code
// main.php
require_once 'table_structure.php';

// Create table query using the defined structure
$tableName = 'users';
$query = 'CREATE TABLE ' . $tableName . ' (';
foreach ($tableStructure as $column => $type) {
    $query .= $column . ' ' . $type . ', ';
}
$query = rtrim($query, ', ') . ')';

echo $query;
