Warning
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change in a future release of PHP without notice. Be warned and use this function at your own risk.

Returns an error message string, or `FALSE` if there are no more error messages to return.

openssl_error_string() returns the last error from the openSSL library. Error messages are stacked, so this function should be called multiple times to collect all of the information.

The parameters/return type of this function may change before it appears in a release version of PHP

Example 1. openssl_error_string() example
    // lets assume you just called an openssl function that failed
    while($msg = openssl_error_string)
        echo $msg . "<br />\n";

> Note: This function was added in 4.0.6.
