The report looks fine (except that one column): all of the other elements of the report - including some generated by other switch statements ( none of which have NULL as a possible value) - look as designed. There is a while loop that spins out the report based on what happens in the while loop. but that is not really productive because maybe in another script you just forget the break and therefore the warning would be of use. PHP Fatal error: 'continue' not in the 'loop' or 'switch' context in continue.php on line 22įatal error: 'continue' not in the 'loop' or 'switch' context in continue.The goal is to produce a report. the only way to get rid of the warning would be to configure the warnings, that phpstorm prints, in this case remove the warning of fall-throughs. PHP Fatal error: Cannot break/continue 1 level in continue.php on line 22 If you need to correct such error cases as part of an upgrade, you may need to substitute either an exit or return to maintain the existing behavior of such legacy code. The first example in this answer is better than all the other answers because it will always correctly match (or not) the subject of the switch(), whereas returning true or false from the pregmatch() ternary could have unexpected results, as in NikiC's empty string example. A value is considered empty if its value is any of the following: An empty string. The empty keyword also evaluates expressions which are not in a variable. ![]() In the one-liner above I ignored the existence of parameters to break/continue, but the one-liner is also valid when parameters are supplied.Īs of PHP 7.0, instead of code executing up until encountering a continue (or break) call outside of a loop statement, the code will simply not execute. The case statement MUST be indented once from switch, and the break keyword (or other terminating keywords) MUST be indented at the same level as the case body. The empty keyword acts as a function which returns true if a variable does not exist, or if its value is considered empty. In the case of (for, while, do-while) loops, resuming execution just prior their closing curly brackets means that a new iteration is started -which is of course very unlike the behavior of a break statement. This made me come up with the following one-liner that describes the difference between break and continue:Ĭontinue resumes execution just before the closing curly bracket ( } ), and break resumes execution just after the closing curly bracket.Ĭorollary: since a switch is not (really) a looping structure, resuming execution just before a switch's closing curly bracket has the same effect as using a break statement. ![]() ![]() The remark "in PHP the switch statement is considered a looping structure for the purposes of continue" near the top of this page threw me off, so I experimented a little using the following code to figure out what the exact semantics of continue inside a switch is:Īnd observed the different results. ![]() Getting Started Introduction A simple tutorial Language Reference Basic syntax Types Variables Constants Expressions Operators Control Structures Functions Classes and Objects Namespaces Enumerations Errors Exceptions Fibers Generators Attributes References Explained Predefined Variables Predefined Exceptions Predefined Interfaces and Classes Predefined Attributes Context options and parameters Supported Protocols and Wrappers Security Introduction General considerations Installed as CGI binary Installed as an Apache module Session Security Filesystem Security Database Security Error Reporting User Submitted Data Hiding PHP Keeping Current Features HTTP authentication with PHP Cookies Sessions Dealing with XForms Handling file uploads Using remote files Connection handling Persistent Database Connections Command line usage Garbage Collection DTrace Dynamic Tracing Function Reference Affecting PHP's Behaviour Audio Formats Manipulation Authentication Services Command Line Specific Extensions Compression and Archive Extensions Cryptography Extensions Database Extensions Date and Time Related Extensions File System Related Extensions Human Language and Character Encoding Support Image Processing and Generation Mail Related Extensions Mathematical Extensions Non-Text MIME Output Process Control Extensions Other Basic Extensions Other Services Search Engine Extensions Server Specific Extensions Session Extensions Text Processing Variable and Type Related Extensions Web Services Windows Only Extensions XML Manipulation GUI Extensions Keyboard Shortcuts ?
