Regarding Anthony's comment: 

Since 5.2.15 the report mode is per request, not per process anymore.

It should be noted that all reports made by this function, are sent through an exception named 'mysqli_sql_exception' instead of a normal PHP warning.

Be very careful using this function - it's a per-process setting.
If your server is set up to reuse a single PHP process for multiple requests, that means the last setting of this function in any script will affect all other scripts using mysqli.
To be safe always call <? mysqli_report(MYSQLI_REPORT_OFF) ?> at the end of a script. The CGI version of PHP is probably safe from this.

(Tested using PHP 5.0.5, Apache 2 SAPI module)

Hint: If you use

mysqli_report(MYSQLI_REPORT_ALL ^ MYSQLI_REPORT_STRICT)

normal errors are generated instead of exceptions.
