https://stackoverflow.com/questions/26431066/continue-2-and-break-in-switch-statement

I have commented out line 338 in /inc/items/items.ctrl.php and all seems fine. I'm not sure why 'continue' is used as there is no code to continue to before the closing bracket. Lools like an imported code that was used for posts and left from the ancient days??

continue resumes execution just before the closing curly bracket ( } ), and break resumes execution just after the closing curly bracket.
https://www.php.net/manual/en/control-structures.continue.php

                   if( $new_Chapter->dbinsert() !== false )
						{ // Category is created successfully
							$Messages->add_to_group( sprintf( T_('New category %s created.'), '<b>'.$new_categories[ $fileNum ].'</b>' ), 'success', T_('Creating posts:') );
							$ChapterCache->clear();
						}
						else
						{ // Error on creating new category
							$Messages->add( sprintf( T_('New category %s creation failed.'), '<b>'.$new_categories[ $fileNum ].'</b>' ), 'error' );
							//continue; // Skip this post
						}
						$cat_Array[ $fileNum ] = $new_Chapter->ID;
						break;

UPDATE: To remove the above errors
I have commented out the lines above that are solely code with continue; to //continue;

UPDATE 2:
Replaced earlier edit with break;

So to summarise.

In PHP, if continue is applied to a switch statement, it behaves the same as break. In other languages, it would continue the surrounding loop instead. To avoid confusion, this RFC proposes to deprecate and remove continues acting on switch.
https://wiki.php.net/rfc/continue_on_switch_deprecation

As since PHP 7.3.* there is a warning for each instance I'm replacing all instances of continue; with break;

And for those interested I will update the list of files here but not the version or line numbers.

So the list so far is

• /inc/items/items.ctrl.php
• /inc/collections/_search.funcs.php
• /plugins/_bbcode.plugin.php
Searched a dozen or so files using the [switch] statement but all use break;

Further Notes

Backward Incompatible Changes
PHP 7.3 throws additional deprecation warnings, PHP 8 generates a compile error. Fixing it is always trivial by replacing continue with break.

Unaffected PHP Functionality
Continue can still be used inside switch statements, as long as it does not target the switch. The meaning of continue and break inside switch never changes, some cases are just forbidden.

To further clarify which uses of continue are affected, please consider the following example:

while ($foo) {
    switch ($bar) {
        case "baz":
            while ($xyz) {
                continue;   // Targeting the inner while loop: Allowed
                continue 2; // Targeting the switch: Deprecated
                continue 3; // Targeting the outer while loop: Allowed
            }
    }
}

we'll fix all that.

Hello @amoun, fixed in commits https://github.com/b2evolution/b2evolution/commit/9b8624dfeea10a62d9e5ef6372e567d9e3cf275b, https://github.com/b2evolution/b2evolution/commit/b244d2290a2f3d33c987603ac9dd60672979934c.

@yurabakhtin Thanks for this and all the others and not just today :)

I am just getting all of these types of errors today. None of these errors were there earlier this morning. I'm running 6.10.1-stable and can't log in to my dashboard when I could earlier today.

Will doing an update fix this?

I checked with my host, and they wrote, "The PHP version was upgraded to 7.3 automatically which was not compatible with your website . So I changed the PHP version to 5.6 to make it work. "

-Brae

Yes you should upgrade. b2evo 6.11.3 is compatible with PHP 7.3.

Perfect, thanks!
