What are potential reasons for a SQL query to return results in phpMyAdmin but not in PHP code?

One potential reason for a SQL query to return results in phpMyAdmin but not in PHP code is that there may be errors in the PHP code that is executing the query. This could include syntax errors, incorrect connection settings, or missing error handling. To solve this issue, you should carefully review your PHP code to ensure that it is correctly connecting to the database and executing the query. 

<?php
// Establish a connection to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Execute the SQL query
$sql = "SELECT * FROM table_name";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Column1: " . $row["column1"]. " - Column2: " . $row["column2"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
