A quick preg_replace question

[evanagee]

hey all!

I've got a simple preg_replace function that looks like this:

$value = preg_replace('/#([A-Z])#/',$row[$1."_col"],$value);

I'm trying to replace the matched result with the value of a key in my array $row named A_col, B_col, etc.

However, this isn't working. Does anyone have any tips that can help me solve this very frustrating problem?

Thanks!

Anyone have any ideas?

Can you be specific? Do you mean you want to replace part of the value? What is the problem? Perhaps you can show more code for context so it's more clear what you are trying to accomplish.

$1 is not a valid variable name.

Variables cannot start with a number.

I believe what you're after is:

$value = preg_replace('/#([A-Z])#/e','$row["$1_col"];',$value);
