What potential issues can arise when using the mysql_list_fields function in PHP?

When using the mysql_list_fields function in PHP, one potential issue that can arise is that this function is deprecated as of PHP 5.5.0 and removed in PHP 7.0.0. It is recommended to use mysqli_fetch_field instead to retrieve information about the fields in a result set.

// Using mysqli_fetch_field instead of mysql_list_fields
$result = mysqli_query($connection, "SELECT * FROM table_name");
while ($field = mysqli_fetch_field($result)) {
    echo "Field name: " . $field->name . "\n";
    echo "Field type: " . $field->type . "\n";
}
