PHP str_replace

[NigelRen]

The simplest way of doing this is having a variable with the previous value in it. So if your working with $word then $prevWord would be the previous version of it. Before making any change to $word - simply use $prevWord = $word;. Then each change would actually be something like...

Code: Select all

$word=str_replace("a","o",$prevWord);
