PHP cent use global variable in class method -

i trying make $var1 work on many different method

var1 outcome of extract() array contains url parts

exp:

$url = 'localhost/site/classname/edit/254/...';

$arr[var1] = 'edit';

$arr[var2] = '254';

$var1 = 'something';  class myclass{     function dosomething(){         echo $var1;     } }  $obj = new myclass(); $obj->dosomething(); 

output:

notice: undefined variable: var1 in....

is there way fix it??

2 ways fix it:

first, best - passing variables function arguments:

$var1 = 'something';  class myclass{     function dosomething($var){         echo $var;     } }  $obj = new myclass(); //you pass constructor $obj->dosomething($var1); 

second, working, considered bad practice:

$var1 = 'something';  class myclass{     function dosomething(){         global $var1 ;         echo $var1;     } }  $obj = new myclass(); $obj->dosomething();
