Re: namespace trouble

Hi Pascal. You seem to have a problem with the scope of your variables. On Thu, 31 May 2007, Pascal Desroche wrote:

<?php //here you are declaring $example in the global scope. $example = "php variable test"; PrintExample(); function PrintExample(){ // now you are trying to access a global variable // inside a function echo "$example"; } ?>

Notice: Undefined variable example

to do this you need to use the global keyword inside the function, like this: function PrintExample() { // tell php you want to access a global variable global $example; // or global $var1, $var2, ... etc echo $example; } It's not good practice to access global variables like that anyway. When you get onto OOP PHP then that would be frowned upon. Usually you would want to pass the global variable as a parameter to the function, like this: PrintExample('testing...'); function PrintExample($example) { echo $example; } HTH Keith ------------------------------------------------------------ http://www.karsites.net http://www.raised-from-the-dead.org.uk This email address is challenge-response protected with http://www.tmda.net ------------------------------------------------------------
