Debugging toolbar/nl

De debugging toolbar is handig voor ontwikkelaars die debug informatie zichtbaar willen hebben van een MediaWiki pagina aan de onderkant van hun browservenster. U kunt het instellen met de variabele in "LocalSettings.php":

The toolbar
The toolbar consists of multiple sections that you click to expand or collapse:



The sections are:


 * Console: An area where MediaWiki code can write messages. Superior to echoing text to the browser.
 * Queries: A list of SQL queries executed on that page, with timing (requires ).
 * Debug log: A list of the debug messages printed during the page execution.
 * Request: HTTP request information.
 * PHP includes: A list of included PHP files during the page execution.
 * The rest: Statistics about the software versions, execution time, and memory used.

Click any section to expand it and see the data. Click it again to close. Use your browser's Find feature to search the data.

The MediaWiki and PHP links lead to their respective websites (https://www.mediawiki.org and https://php.net).
