• PHP - Replacing Strings With Other Strings

  Posted on April 15th, 2009 admin No comments

  This is a very useful function to include in web forms or anywhere where user’s can leave input. What this function does is replace strings with strings for example, replacing swear words with something else such as ‘****’. This can be easily done in PHP by using the following format:

  str_replace(findwhat, replacewith, whichstring)

  If we used this format we could produce the following:

  $modifiedcomments = str_replace(”water”, ‘fire’, $comments);
  echo $modifiedcomments;

  This will replace water with fire in the variable $comments. So when the script get’s processed a new variable called $modifiedcomments will be created and if it finds the word or string ‘water’ it will be replaced with ‘fire’.
