variable array

Jun 13th, 2008

I have a large multidimentional array that I am looping through to change it's structure and theoretically this function will work accept the "variable array" part. And maybe that's not the right name for it as I have checked my resources and cannot come up with the right syntax for it but theoretically, I think I should be able to do it.

If you know what a variable variable is:

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
$variable = "blue";
$$variable = "red";
 
//what you get is
$blue = "red";
$variable = "blue";
$$variable = "red";

//what you get is
$blue = "red";

I am trying to do the same thing with an array:

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
$variable = "blue";
$$variable[] = "red";
 
//what I want is
$blue[0] = "red";
$variable = "blue";
$$variable[] = "red";

//what I want is
$blue[0] = "red";

Does that make sense?

the syntax you are looking for is:

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
$variable = "blue";
${$variable}[] = "red";
 
//print array to see if it worked (did for me)
print_r(${$variable});
$variable = "blue";
${$variable}[] = "red";

//print array to see if it worked (did for me)
print_r(${$variable});
