What is the cause of the error 'Call to a member function on a non-object'? Differences

It usually occurs when you are hacking a script or joining 2 scripts together. It basically means one of 2 things:

+1. Clash of naming conventions. (meaning some code clobbered the variable you're trying to call as an object)

-1. Clash of naming conventions.
+2. Object not being instanciated. (meaning you forgot to 'make' the object)

-2. Object not being instanciated.
+3. Calling -> on an variable that is not an object (because you misstyped the variables' name (use error_reporting(E_ALL) to fix that), or because you are using the wrong one)


DmS has supplied a little bit of script which will dump the variable data onto the page:

print("<pre>");
print_r(&#91;b&#93;$variable&#91;/b&#93;);
print("</pre>");

This should help you spot if there is a clash of naming conventions otherwise you will have to pik through your script to identify where the problem with the object comes in.
