PHP MySQLi mysqli_thread_safe() - Thread Safety Check

mysqli_thread_safe()

The mysqli_thread_safe() function returns information on whether the MySQL client library used by PHP was compiled as thread-safe.

EXAMPLE

<?php
// NOTE: Please note that the mysqli_thread_safe() function DOES NOT require 
// a $connection object as its first parameter! It operates at the level of the PHP extension itself.
$thread_safe = mysqli_thread_safe();

if ($thread_safe) {
    // In the real world, modern production servers almost always return TRUE
    echo "Your MySQLi library is compiled as thread-safe.";
} else {
    echo "Your MySQLi library is not thread-safe.";
}
?>

RESULT

The result will be displayed here...

Practical use: This function is primarily intended for system administrators and developers who need to ensure that their application runs stably in a multi-threaded environment (e.g., on specific configurations of Apache or IIS servers).

It returns TRUE if the library is thread-safe, otherwise it returns FALSE.

It helps in diagnosing the stability of the server environment.

It does not require any parameters for its operation.
