undefined variable accepted

[caseyc]

I have a script which is working however, I do not receive any errors when I use a variable which has not been declared or initialized. For example I can write
echo $kjhkj;
and while nothing appears in the resulting page neither do I get an error to say that the variable is undefined.
register_globals are set to "off" by the way.
Any help appreciated.

Well, you need to check whether a var isset is you want to be sure.

Register globals being off, as interesting as that is, doesn't really matter here. You might want to check/change some more applicable configuration settings, such as the error_reporting level, and the state of display_errors, in addition to following leatherback's suggestion.

will give that a go and have a look at the error reporting settings.
Thanks very much.

Ok. - tried isset() and result said it was not set
- display_errors is set to "on"
- error_reporting = E_ALL & -E_NOTICE & -E_STRICT
and still no error re. the variable. Maybe this is not unusual for PHP but I have definitely received undeclared variable errors before this.
