Pulling variables from str_replace

[Brad Everman]

Something simple, perhaps someone can shed some light.

I have an array of paragraphs of text and am replacing some of the text
using str_replace().

Ex.

function addGraphic($numGraphic){

return("this is graphic $numGraphic");

}

$instruction = str_replace("#GRAPHIC[$i]",addGraphic($i),$instruction);
Basically, I look for the tag #GRAPHIC[n] in the text where n is an
integer value and want to replace it with the text and the actual number
inside the brackets. I am unsure how to parse this value out and then pass
it to the function that will create the appropriate output.

Thanks for any help.

Hey Brad,
You need preg_replace_callback(). str_replace() won't work with more
than one string unless you make a huge array for the search and replace
params.

Thanks, that worked perfectly.
