Php Fatal Error Cannot Redeclare Function
them; it only takes a minute: Sign up Fatal error: Cannot redeclare class Database up vote 4 down vote favorite i have fetal error message say : Fatal error: Cannot redeclare class Database in C:\wamp\www\pets_new\lib\database.php on line 3 require_once("lib/message.php"); http://stackoverflow.com/questions/11186348/php-how-to-resolve-cannot-redeclare-class-when-theres-no-previously-declare require_once("lib/user.php"); and all connect to database class Class message http://stackoverflow.com/questions/23058671/fatal-error-cannot-redeclare-class-database Check inside your user.php or message.php file. You have already include a database.php file where class Database is already declared. –Neeraj Kumar Apr 14 '14 at 11:23 add a comment| 3 Answers 3 active oldest votes up vote 5 down vote You include 2 files in a single "run". Think of it like this: All the included files are put together by PHP to create one big script. Every include or require fetches a file, and pastes its content in that one big script. The two files you are including, both require the same file, which declares the Database class. This means that the big script that PHP generates looks like this: class Message {} class Database {}//required by message.php class User {} class Database {}//required by user.php As you can see class Database is declared twice, hence the error. For now, a quick fix can be replacing the require('database.php'); statements with: require_once 'database.php'; Which checks if that particular file hasn't been included/required before. If it has been included/required before, PHP won't require it again. A more definitive and, IMHO, better solution would be to register an autoloader function/class method, and let that code take care of business. More on how to register an autoloader can be found in the docs. If you go down this route, you'd probably want to take a look at the coding standards concerning class names and namesp
Troubleshooting » Upgrade to 4.5.2 get PHP Fatal error: Cannot redeclare class WP_Screen Upgrade to 4.5.2 get PHP Fatal error: Cannot redeclare class WP_Screen Geoffd99 @geoffd99 4 months ago Hi all Hope you can help, I did the upgrade to 4.5.2 and then - no admin to site, white screen https://wordpress.org/support/topic/upgrade-to-452-get-php-fatal-error-cannot-redeclare-class-wp_screen/ (plus errors if debug on). I have now put on debug to log file, there are warnings, the fatal error is this: [21-Jun-2016 14:14:51 UTC] PHP Fatal error: Cannot redeclare class WP_Screen in …/wp-admin/includes/screen.php on line 209 I have switched off all plugins inc askimet, except w3-total-cache since the website still works live, so don't want to mess up the cache. if this is the problem, is very risky to remove (or switch off) the cache and lose the site cannot redeclare forever. At least it is still working. Previously: I had a white dashboard, only the left side menu showing for plugins, WP functions showed a white screen. I fixed this by a one line edit to screen.php (and was working fine). I have tried it now with original and edited screen.php version, same fatal error. I have tried replacing http.php with an older one (4.4) this has made no difference. Tips welcome! I am OK with a bit of coding. cannot redeclare class Thanks all, Geoff Viewing 15 replies - 1 through 15 (of 16 total) 1 2 → Tara @t-p 4 months ago Have you tried: - deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, re-activate them individually (one-by-one) to find the problematic plugin(s). - If you can't get into your admin dashboard, try resetting the plugins folder by FTP. Also remember to deactivate any plugins in the mu-plugins folder (if you have created such folder). The easiest way is to rename that folder to mu-plugins-old. - switching to the unedited default Theme (Twenty Sixteen, etc.) for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins). If you don't have access to your admin area, use FTP , or your web-host's cPanel or whatever file management application your host provides (no Dashboard access required). Navigate to /wp-content/themes/ and switch to the default theme by renaming your current theme's folder by adding "-old" to the end of the folder name. Alternately, you can remove other themes except the default theme. That will force your site to use it. - If all the above steps do not resolve the issue, then try MANUALLY updating. Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config.php fil
