bug or syntax error?

[casper_ghost]

Hi all

 

while in the process of learning php, I wrote some code and couldn't work out why it wouldn't work,

 

After going through everything with a fine tooth comb I couldn't see the problem.

Then out of luck I removed

 

$this 

 

I had assigned as a variable and it worked. replacing it back into the code broke it again.

 

Is this a bug or does it mean something in php?

$this is reserved. See the manual for more info:

The pseudo-variable $this is available when a method is called from within an object context. $this is a reference to the calling object (usually the object to which the method belongs, but possibly another object, if the method is called statically from the context of a secondary object).

Additionally, you should be developing with the following directives set in your php.ini file (then restart Apache):

error_reporting = -1

display_errors = On

 

If you had error_reporting set appropriately, you would have gotten this error:

Fatal error: Cannot re-assign $this in /Applications/MAMP/test.php . . .

thank you for your replies,

 

I know it should be turned on, I turned it off some time ago to force myself to look for bugs when the code breaks... but it will be a good idea to turn it on next time i can't find the error.

 

cheers guys.

You should always develop with error reporting and display error on.
