Extracting Text from between parentheses in PHP using preg_replace
- by Christopher
I am trying to take a string of text like so:
$string = "This (1) is (2) my (3) example (4) text";
In every instance where there is a positive integer inside of parentheses, I'd like to replace that with simply the integer itself.
The code I'm using now is:
$result = preg_replace("((\d+))", "$0", $string);
But I keep getting a "Delimiter must not be alphanumeric or backslash" error.
Any thoughts? I know there are other questions on here that sort of answer the question, but my knowledge of regex is not enough to switch it over to this example.
