[SOLVED] How to declare global variables?

[kks_krishna]

HI,

 

How can i declare a global variable to a class or a file?

[bwochinski]

In a class global variables are declared at the beginning of the class outside of any functions.

 

Not sure what you mean about the file...

[kks_krishna]

how can i delare outside and improt to all the classes. for example i have some commmon variables to be across all the files. so i want to delare those varibles in seperate files and use it on other files. how can i do that?

You can keep like this

define("CONSTANT", "Hello world.");

HI,

 

How can i declare a global variable to a class or a file?

 

i believe you dont know what your asking??

[kks_krishna]

Let me put it clear.

For example I have two files : detail.php and common.php

 

Here detail.php is the file where we write the logic. Common.php is used for delaring all the common variables used across the files. take one scenario, i want to display 10 rows per page, so i will add one variable as rows_per_page = 10; in common.php. I want to use this varible in detail.php bcos it can be used in other files also. so did like this:

 

common.php

-----------

class{

  rows_per_page=10;

}

 

detail.php

---------

 

class Detail{

    function m(){

        // i want to use that variable here. how can i do that.

    }

 

 

Pleaes help me.

 

}

common.php

 

//Class not needed here...
/*
class{
   rows_per_page=10;
}
*/

//instead... and you can use '10' (single quoted) if you want it a string

define('_ROWS_PER_PAGE', 10);

 

detail.php

 

class Detail{
    function m(){
        echo "Rows Per Page = " . _ROWS_PER_PAGE;
    }


}

Yep... just require_once('Common.php'); should do the trick...
