handling errors !

[xploita]

when coding.say that i call function UpdateLog() which must open a file,append to it then close it.

alot of errors could rise(file is not there,unable to write..etc).

which is better,to return a false value and handle the error outside the function UpdateLog(),or to end it right there inside the UpdateLog() function if it couldn't find/update the file?

I'd would handle all error aspects which the file you are writing to having write permission, file not found etc in side the function itself.

inside which funciton ?

the calling function or the one that actually writes to the file?

a wild guess... inside the function that writes to the file...

IMO its best to have the calling code decide wether or not to kill the application based on wether or not your function call failed or succeeded. If your using PHP5, use exceptions, this makes this sort of descision making alot simpler.

i agree with thorpe. if you're writing a class or a function, you probably use it more than once and for different apllications of that function, you might have to react differently based on the error.

 

thorpe mentioned exceptions in PHP 5 (i'm only just learning that :/), but if you're on PHP 4, try set_error_handler() and trigger_error()
