Question

I have a string like:
$string = “/physics/mechanics/vectors/P-M-C (1).doc”;

I want to get like this:

“/physics/mechanics/vectors/1-P-M-C (1).doc”;

Please note that “1-” is added just before P in the original string.

Is it possible in PHP?
How the function in PHP should be used?

@fawad:Here’s a sample to get you started —

$oldstring = "/physics/mechanics/vectors/P-M-C (1).doc";
$parts = explode("/", $oldstring);
$file = $parts[count($parts) - 1];

$newstring = str_replace($file, "1-" . $file, $oldstring);
