referring to variable name using string:

[zcabeli]

Hi,
i want to refer to variable using a string that represent its name.


i.e. in this example (which doesn't work ) i'd like to place value of 6 in 'y':

$x = "$y";
$y = 5 ;

eval($x) = 6;

can you tell me what is the correct way to do it ?

thanks,

Use a reference:

$y = \$x;
$x = 6; 
print ${$y};
 

a simple hash is probably better than using references for scalars. References are best left for more complex data, but you can use them for this purpose if you really want to.
