Here's an example of how the error might appear in a Codeigniter application:
The "Commands out of sync; you can't run this command now" error in PHP usually occurs when you have called a MySQL function in an incorrect order.
The mysqli_stmt::bind_result() method binds variables to a prepared statement for result storage.
The "Fatal error: Call to undefined function mysqli_connect()" error in PHP typically occurs when the MySQLi extension is not enabled or properly configured in your PHP environment.
You can use the mysqli_fetch_assoc() function to retrieve an associative array of a single row from a result set, and use a loop to iterate through the result set and store each row in an array.
If you are seeing this error message in PHP, it may be caused by a mismatch between the version of the PHP client library that you are using and the version of the API that it is trying to access.
To enable the MySQLi extension in PHP 7, you need to follow these steps.
To display a MySQL error in PHP for a long query that depends on user input, you can use the mysqli_error() function.
To install MySQLi on a Mac, you will first need to install the MySQL database server on your machine.
mysqli and PDO are both PHP extensions used for interacting with databases.
