  - by aioobe

  I'd like to censor some words in a string by replacing each character in the word with a "*". Basically I would want to do String s = "lorem ipsum dolor sit"; s = s.replaceAll("ipsum|sit", $0.length() number of *)); so that the resulting s equals "lorem ***** dolor ***". I know how to do this with repeated replaceAll invokations, but I'm wondering, is this possible to do with a single replaceAll?

• C#, why does Convert.ToBoolean("0") fail?

  - by JL

  I know that trying to convert string "0" to boolean will fail, I also know how to fix this, thanks to Jon Skeets answers on other questions. What I would like to know is WHY does C# not recognise "0" as a valid input for a boolean conversion, surely you could look at it like 0 = false, 1 = true, or even -1 = false and 0 = true, anyways, my logic tells me that it could be a valid input, so is there a very good reason why its not? My bet is old vb6 would be able to recognize the string input "0" as valid.

• preg_replace replacing with array

  - by Scott

  What I want to do is replace the "[replace]" in input string with the corresponding vaule in the replace array. The total number of values will change but there will always be the same number in the replace array as in input string. I have tried doing this with preg_replace and preg_replace_callback but I can't get the pattern right for [replace], I also tried using vsprintf but the % in <table width="100%"> was messing it up. All help is greatly appreciated! Replace Array: $array = array('value 1','value 2','value 3'); Input String $string = ' <table width="100%"> <tr> <td>Name:</td> <td>[replace]</td> </tr> <tr> <td>Date:</td> <td>[replace]</td> </tr> <tr> <td>Info:</td> <td>[replace]</td> </tr> </table> '; Desired Result <table width="100%"> <tr> <td>Name:</td> <td>value 1</td> </tr> <tr> <td>Date:</td> <td>value 2</td> </tr> <tr> <td>Info:</td> <td>value 3</td> </tr> </table>
