What are the potential issues that can arise when using variables with the same name in MySQL procedures and PHP scripts?

When using variables with the same name in MySQL procedures and PHP scripts, it can lead to conflicts and unexpected behavior. To avoid this issue, it is recommended to use different variable names in each context to ensure clarity and prevent any unintended consequences. 

// Example of using different variable names in MySQL procedures and PHP scripts
$phpVariable = 10;

$query = "SELECT @mysqlVariable := 20";
$result = mysqli_query($connection, $query);

if ($result) {
    $row = mysqli_fetch_assoc($result);
    $mysqlVariable = $row['@mysqlVariable'];
    
    echo "PHP variable: " . $phpVariable . "<br>";
    echo "MySQL variable: " . $mysqlVariable;
}
