![]() ![]() 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. the following program demonstrates the use of exit statements.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 ?

The following example uses the continue statement to print upper and lower a to z alphabets.When compiler encounters continue, statements after continue are skipped and control transfers to the statement above continue.Similar to break statement, continue is also used with if statement.A continue statement can be used into the loop when we want to skip some statement to be executed and continue the execution of above statement based on some specific condition.The default value is 1, means only the immediate enclosing structure is broken out of. ![]() break can also be used with an optional numeric argument to specify how many nested enclosing structures are to be broken out of.Loop will be terminated as soon as the counter value becomes greater than 5. The following program demonstrates the use of break statement.When certain condition becomes true to terminate the loop then break statement can be used.A break statement is normally used with if statement.Whenever, break statement is encounter within the program then it will break the current loop or block.It can be used in switch statement to break and come out from the switch statement after each case expression. ![]()
