Timothy Boronczyk's Blog:
Goto and Exceptions
Mar 24, 2009 @ 13:57:12

Timothy Boronczyk has written up a nice post about two practical uses of the "goto" syntax in the upcoming PHP 5.3 release of the popular web scripting language.

Yet goto can still be useful under certain circumstances. For example, some programmers use goto to direct the execution flow to dedicated error-handling logic elsewhere in a program in languages that lack exception handling (such as C).

His two examples are to: emulate exception handling in a procedural environment and to overcome perceived limitations with try/catch. He adds in some code comparing the "without goto" and "with goto" versions of the same code showing how the exception handling might be handled differently.
