Replace with Dynamic variable in preg_replace


Recommended Posts


I'm trying the following code:

$t = '12<-- AB_C -->';
$AB_C = 'abc';
echo preg_replace('/\<-- ([A-Z_]+) --\>/', "$$1", $t);

I want to get "12abc" , but it outputs: 12$AB_C , so, it not recognize the replacement as dynamic variable.

Is it any way to use the matched word in preg_replace() as a variable, or dynamic variable?
