[RESOLVED] Variable within a variable (in the array key)?

[sam8perry]

Hello

I am trying to put a variable into a variable but in the array key part. What I am trying to achieve would be simply something like this:

$array['stock_$variable']

where the variable inserted is $variable and actually makes up part of the array key.

Is this even possible?

I am aware that to place a variable within a variable I could use the following:

${"array_{$variable}"}['stock']

and this understanding leads me to believe that this should work:

${"array_['stock_{$variable}']"}

but it doesn't and I don't seem to be able to place the variable actually into the key.

I hope this makes sense. Thanks for any suggestions.

Use double quotes or else concatenation, as variables are not interpolated within single quoted string literals.

$foo["string_$bar"] /* OR */ $foo['string_'.$bar]

Or, consider using a multi-dimension array, which better represents your data structure anyway:

$array['stock'][$variable]

But that would suggest that the array index name is stock_$variable. See the manual page for what a [man]string[/man] is, but here's a quick example:

$msg = "Hello world!";

echo 'Test1: $msg';
echo "\nTest2: $msg";

Output:

Test1: $msg
Test2: Hello world!

EDIT: Nog beat me to it ;o
