Procedural style:
string
mysqli_error ( mysqli link )
Object oriented style (property)
class
mysqli {
string error
}
The mysqli_error() function is identical to the corresponding
mysqli_errno() function in every way, except instead of returning
an integer error code the mysqli_error() function will return
a string representation of the last error to occur for the database connection
represented by the link parameter. If no error has occured,
this function will return an empty string.
